Bernhard and I hope you enjoy reading this issue ofFiberSpectrum. As head of thePulp Mill Technologies sector ofAndritz, I would like to direct yourattention to the articles aboutUPM-Kymmene's Kuusankoskimill (page 4) and Portucel'sSetubal mill (page 18). Inaddition, our Wood Processinggroup contributed to thesuccess of Holmen Paper'sHallstavik operations (page 14).Andritz is proud to have playeda major role in these projects.

The year 2003 was a difficultone for most of the industry,including suppliers. Still, we arefortunate to have been chosenfor major greenfield projects,such as the Veracel project inBrazil. We are well underwaywith large chemical pulpingand recovery projects in Chile,Germany, and Finland. Ofspecial note is the verysuccessful start-up in August2003 for a new Andritz fiberline in the USA.

Within nine days, the line reached design production, hasproduced on-grade pulp, and the average production hasbeen above the design rate ever since. These areexceptional results!

We thank you for your continued confidence in ourpeople, our technology, and our service.

Sincerely,

Markku HänninenHead of Pulp Mill [email protected]

Our strategy to create full-linecompetence within Andritzproves to be successful. Forexample, we sold two complete3000 admt/d pulp drying linesin 2003 (China and Brazil)which include the recentlyacquired Fläkt Dryer technology.And, we now have the potential to supply completemechanical pulping systemswith Flash dryers.

In this issue, you will findarticles of interest for tissueproducers, such as the CCMproject for Metsä Tissue (page8). The TissueFlex™ shoepress technology is now well-proven with 10 machines inoperations producing supersofttissue quality. The most recentexample is Wepa in Germany,which had an excellent start-up.TMP producers will want toread the results of HolmenPaper's RTSTM refiner upgradeproject (page 14). And,

recycled fiber producers will be interested in the Andritzturnkey DIP line for Krsko in Slovenia (page 24). Wecontinue to make investments in the service area, mostrecently with the acquisition of Fiedler — a major supplier ofscreen baskets for our industry.

We appreciate your feedback and will consider everysuggestion.

Sincerely,

Bernhard RebernikHead of Paper Mill [email protected]

Sulphate pulp production began in1964 and the pulp mill has steadilyprogressed over time — from 150,000t/a to today's 500,000 t/a of bleachedhardwood and softwood.

Today, with major modernizations toboth the pulp mill and paper mill, UPM-Kymmene in Kuusankoski continues tobe well-positioned as a supplier of new-generation publication papers on its fivepaper machines.

Downflow Ups Strength and Capacity at Kuusankoski

Above: Auvo Kettunen, Development Manager for Cooking Processes at Andritz.Right: The softwood digester (left) rebuilt by Andritz produces 200,000 t/a bleachedsoftwood pulp. It utilizes Downflow Lo-Solids® Cooking and Enhanced Alkali ProfileCooking (EAPC) to improve pulp strength and yield. The new 1000 t/d Andritz digester(right) with Lo-Level® Feed and Lo-Solids® Cooking has performed with 100% availability.

The history of Kymmene Corporation started in Kuusankoski, Finlandin the year 1872. Situated on the banks of the Kymi River, the mill waswell-positioned amidst water, fiber and energy resources.

New digester for hardwood line

"We had two Ahlstrom digesters fromthe mid-1960's and they were runninggood," says Markku Laaksonen, PulpProduction Manager at Kuusankoski."The only problem was that, due totheir age, they were very badly corrod-ed. The shells were fabricated fromcarbon steel. The cost of maintenanceand repair was quite high."

Another factor was the paper mill'sprogram to increase capacity, which putnew demands on the pulp mill.

"The starting point for choosing thecooking process is always the same —produce high quality pulp at low costs,simply and safely," Laaksonen says."When we got approval to purchase thenew digester, we were satisfied that theAndritz single-vessel hydraulic technol-ogy would meet our goals. We thoughtthat the Diamondback® Chip Bin andthe feeding system were simple andgood. We also felt we would get moreyield from the Andritz system, com-pared to their competitors."

The new 1000 t/d Andritz digester, withLo-Level® Feed and Lo-Solids® Cooking,was started up in September 1999 aftera quick 14-month delivery time.

"Start-up of the Andritz digester wasvery easy," Laaksonen remembers. "Wehad a one-month water run before westarted cooking. We ramped the tem-peratures up and had time to adjust thecontrol loops, and get everything right.

Chip feeding to the digester began on5 September and that same evening,first-class pulp was being produced.

"It is a very easy digester to run,"Laaksonen explains. "Availability hasbeen100%. We are easily getting 1100 t/dor more. We have had very fewdisturbances, and no scaling problems,of which we had quite a lot with the olddigester."

UPM-Kymmene

The UPM-Kymmene Group, with

sales over 10 billion euros and

36,000 employess, is one of the

biggest forest industry enterprises

in the world.

Although UPM-Kymmene can

trace its roots back to the 1870's in

Finland, the current corporation was

created in 1995 with the merger of

Kymmene Corporation and United

Paper Mills Ltd. (Repola Ltd.).

The company focuses on maga-

zine papers, newsprint, fine and

specialty papers, converting mate-

rials, and wood products. UPM-

Kymmene has production in 17

countries with total papermaking

capacity of 8.6 million t/a.

Downflow Lo-Solids®/EAPC Cooking

The Downflow version of Lo-Solids®

Cooking extends the first cooking

zone to the old extraction screens

of a conventional digester. This

increases the total production capa-

city of the digester. Before the sec-

ond cooking stage there is a short

counter-current displacement zone

(the heart of the Lo-Solids® cooking

process). As with all Lo-Solids®

cooking processes, the dissolved

organic substances are extracted

before bulk delignification occurs,

while the akali profile is optimum.

Cleaner pulp is produced, tear

strength is preserved, and bleaching

is done more efficiently since the

dissolved organics are eliminated.

As the cooking time is longer,

and even though the alkali concen-

trations are lower with Downflow,

cooking temperatures can be much

lower compared to conventional

cooking. The combination increas-

es pulp strength.

Enhanced Alkali Profile Cooking

(EAPC) can be used when maxi-

mum tear strength is needed.

EAPC raises the alkali charge and

the alkali concentration in the

cooking stage so that residual

alkali from the lower extraction is

high. This further reduces the

cooking temperature. This alkali-

rich black liquor is recycled to the

impregnation zone and consumed

there. With a combination of

Downflow Lo-Solids® and EAPC, it

is easy to optimize the effective

alkali profile — giving the operator

the ability to select for pulp yield,

pulp strength, and bleachability.

"The Diamondback®

Chip Bin and the

feeding system are

simple and good,"

according to

Laaksonen.

Today, the line produces 300,000 t/aof bleached hardwood pulp. Pulp prop-erties are good. Kappa 18 is easilyreached at a high viscosity around1400 mg/ml. Total rejects have aver-aged 0.8% and wood consumption isdown 3%. The pulp bleaches to its tar-get 91 ISO using less ECF bleachingchemicals than before.

Downflow Lo-Solids®

retrofit for softwood line

Kuusankoski's old softwood digester,supplied by Ahlstrom in the 1970's, wasrunning vapor-phase technology with ablack liquor impregnation tower. Overthe years, corrosion took its toll. A cor-roded impregnation tower was replacedin 1993.

"This digester has always experi-enced hanging problems on pine, dueto its height and narrow diameter,"Laaksonen confides. "Plus, we hadsome pulp strength problems in thepast which caused us to buy pulp fromthe outside."

UPM-Kymmene chose to rebuild,rather than replace, the softwooddigester in 2000 and again selectedAndritz. This time, the decision wasmade to rebuild the two-vessel vapor-phase digester with a combination ofDownflow Lo-Solids® and EnhancedAlkali Profile Cooking (EAPC) toimprove pulp strength and yield.

Current pulp production for the soft-wood line is 200,000 t/a bleached. Thekappa target is 30 and the brightnesstarget is 87 ISO.

The newly rebuilt softwood digesterstarted up in January 2001. Since thattime, the mill has run extensive strengthtests on the softwood pulp. Remarkably,strength delivery in the blowline has gonefrom 84.7% before the rebuild to 90.9%with Downflow Lo-Solids® Cooking.

"The quality of the pulp is good andhomogeneous," Laaksonen says. "Wechose the Andritz technology to getmore strength in the pulp and we haveachieved this. All our paper machinesnow use the pulp from our own line andwe have stopped purchasing softwoodpulp from the outside."

Since the initial rebuild, Andritz hasfurther refined the digester to increasecapacity and runnability of Kuusankoski'ssoftwood line.A new screen zone was installed duringsummer shutdown (2003) that decreas-ed the alkali charge, lowered the cook-ing temperature, and further increasedpulp strength.

"The digester is running very stablyand pulp strength has increased," saysLaaksonen. "Our aim is to get moreproduction with stable quality out of thisdigester. The demand is there." ■

Metsä Tissue's two mills in the Småland area of Sweden have been quietly at the forefront in two new andextremely interesting developments in the tissue industry: the Compact Concept Mill and the TissueFlex™*press. Andritz played a key role in both.

Clear focus on markets and profits

Metsä Tissue is a recognized innovatorin the European tissue business. Withan annual capacity of 450,000 tonnes,it is number six in world rankings.Metsä Tissue production units arelocated in Sweden, Finland, Germany,and Poland. The company has a clearstrategy focusing specifically on marketsectors where it can achieverespectable market position.

Metsä Tissue, formerly known asMetsä Serla, has nine mills, with threelocated in Sweden. Beginning in 2004,the Metsäliitto Group became the prin-cipal owner of Metsä Tissue (66%share). This ownership restructuringsupports Metsä Tissue's activities tofurther develop its business to becomethe world´s top supplier of Tissue andBaking & Cooking products.

Jarkko Kaplin is the Supply TeamManager for Metsä Tissue in Sweden.In this role, Kaplin is responsible forproduction at the company's threeSwedish mills. The Mariestad mill has

a capacity of around 75,000 t/a of bothconsumer and away-from-home grades.The Nyboholm and Pauliström mills,located within 8 km of each other in theSmåland region, have a total capacityof 45,000 t/a of converted products.The majority of this tonnage goes intoconsumer grades.

Comfort, and quality, for every day

Kaplin explains some of the companybackground and strategy: "Metsä Tissueis a very focused company, with Europeas our main market area. Turnover wasaround 659 million euros in 2002 andabout 55% of our production went tocontinental Europe, 35% to the Nordiccountries, and 10% to other markets.We are strongest in the Nordic countries

where we have approximately 45% mar-ket share, depending on the grade. Ofcourse, when you have a high marketshare, it is a tough fight to keep thislevel, but we have been able to maintainit based on factors such as quality, serv-ice, and delivery times — a function ofour localness so to say. Quality is clear-ly a very important factor for us."

Indeed, the push to increase qualitywas the driving force for two recentinvestments in the Nyboholm andPauliström units, which are collectivelyreferred to within Metsä Tissue as "theSmåland mills." During the period1999-2000, the Småland mills under-went major investments.

Following these and later investmentsin converting technology, says Kaplin, theSmåland mills are presently the "mostcomplete invested operations in the com-pany, and also produce the best quality."

Pioneering a new concept

In 1999, Metsä Tissue introduced a newconcept — the Compact Concept Mill orCCM — for tissue production focusedon optimizing investment efficiency andproduction efficiency. The idea of CCMis to get better profitability by locatingthe papermaking and converting opera-tions into one seamless process. Inother words, CCM blurs the traditionalboundaries between the paper and con-

verting sides. "The boundaries, includ-ing employee workflows and attitudes,have disappeared," Kaplin says.

This new concept, combined with avery steady paper machine productionrate, leads to higher overall productionefficiency from the total assets. "Thelayout and employee attitude is such,"says Jan Eklund, Technical Manager forthe Småland mills, "that the machineoperator keeps a close eye on theprogress in converting. The operator's

goal is to maximize the quality and effi-ciency of our final output, not just build-ing parent rolls as fast as possible."

Eklund explains some of the back-ground: "Back in 1997 we were lookingat alternatives for our future growth. Wewanted a concept that was sized rightfor our market, where we already havea large share. We needed somethingthat gave us premium quality, invest-ment efficiency, and production effi-ciency in a small package at a goodprice. Therefore, we came up with theCompact Concept Mill Project.

"To be honest, I was hesitant at firstwhen it was suggested that we build apaper machine designed for 1000 m/minand not higher. Papermakers alwayswant something bigger and faster thanwhat anyone else has. It is also natu-ral in this industry to build a machinedesigned for one speed but then to

They listened and gave us what we wanted."

slowly move up the speed curve. Buteventually, I was convinced that if wehad the discipline to design, build, andpay for only the specific functions weneeded, we could get a more rapidpayback from running the mill at steadyoutput."

Working closely with a consultant,Metsä Tissue started to define the con-cept in more detail. Nyboholm was cho-sen for this concept, says Eklund, basedon the special mentality and enthusiasmthat is present in the labor force.

As the project developed and suppli-ers were chosen, an efficiency taskforce team was formed. This includedall of the suppliers to the project. Thisteam met regularly to make sure that allthe participants in the project werecommunicating and moving in the samedirection with the efficiency and qualitytargets clearly in focus.

Small is beautiful, and efficient

Metsä Tissue decided from the startthat it did not want to have the world'sfastest or biggest line. Using "smallcan be beautiful" thinking, the designteam decided to keep the line simple.To keep costs down, the line wouldinclude one paper machine, one con-verting line, one wrapper/bundler, andone palletizer. In this single-line sce-nario, selection of the individualmachines was critical to the successof the CCM.

The Andritz tissue machine wasdesigned to run at about 1000 m/min.The theory was that, for this mill, the1000 m/min speed would deliver betteroverall efficiency than would a higherspeed machine.

Another interesting feature is thephysical layout of the line. "As part ofthis focus on simplicity and efficiency,we also wanted to emphasize theteamwork aspect. So we gave thoughtto devising ways to integrate the line sothere are virtually no visible boundariesbetween the papermaking and convert-ing operations," Eklund says.

From the control room, the opera-tors can see almost the entire processfrom the paper machineheadbox through to finishedproduct on pallets going outto the loading bay. This, saysEklund, gives the shift per-sonnel more incentive towork together to keep theentire line running wellrather than focusing on just one unit.By laying the line out in this manner,the paper machine operator has a sec-ondary responsibility to help the con-verting operators, which is somethingthat is almost unheard of in the tradi-tional mill where there are physicalboundaries, and often long distances,between the papermaking and con-verting operations.

Here's a quick test for you:

Which company is Scandinavia's

largest importer and distributor

of plush animal toys?

(Hint…it's not Toys ‘R’ Us).

Actually, somewhat surprisingly,

it is Metsä Tissue! The company

gives away soft lambs (Lambi

brand) as part of its brand promo-

tion campaign. Over one million

super-soft lambs are given to loyal

buyers of Lambi tissue products.

Metsä Tissue has built the Lambi

brand up to be the

leading premium

tissue product:

bathroom tissue,

household towels,

all-round towels,

and handkerchiefs.

As further indication of it success,

Lambi was recently named the

best tissue product in Sweden in

a survey done by the Dagens

Nyheter, the country's largest

daily newspaper.

Smooth start-up for the line

PM 5 is a CrescentFormer machinefrom Andritz. The company choseAndritz after talking with all of the tissuemachine suppliers. Says Eklund,

"Andritz was willing to work with us onthis concept, which wasn't exactly anoff-the-shelf solution. They listened andgave us what we wanted.

"Essentially, everything that Andritzwas responsible for, including stockpreparation and PM 5, started well,"Eklund says. "After start-up, the Andritzmachine ran for 13 hours without abreak. It started so well that initially theconverting line could not keep up. But,we soon got everything into balance."The bottom line is that all this emphasison simplification of the machinery andsystems led to very significant savingsin the purchase price of the equipment.

"The key thing is that we were lookingat efficiency of the whole line over a

longer period," Eklund says. "It doesn'tmake much sense to have a papermachine that can run very fast some ofthe time, but doesn't keep pace all thetime. Or, one that runs too fast for theconverting lines."

Pauliström gets TissueFlexTM

press for bulk

Following the CCM project, and inkeeping with the emphasis that MetsäTissue has on quality, the companyadded a TissueFlex™ shoe press on itsPM 6 at the Pauliström mill in April2000. This was among the first installa-tions in the world of this tissue pressingconcept. The TissueFlex™ version wasdeveloped based upon the extensiveexperience Voith (Andritz's cooperationpartner for tissue machines) had withshoe presses for other paper grades.The principle of TissueFlex™ is tospread the press impulse out over a larg-er area to help retain bulk in the sheet.

12 FiberSpectrum Issue 1 — 2004

Quality was clearly the number one priority with the TissueFlex™ project at Pauliström.Bulk increased 13-22% and there have been important improvements in absorption, uni-formity, and handfeel.

shoe press was added to the machine in April2000. This TissueFlexTM at Paulstrom wasamong the first installations based upon theexperience Voith had with shoe presses forother paper grades.

1212_04_fiberSpectrum_04.qxp 02.04.2004 12:35 Seite 12

Quality was clearly the number onepriority with the TissueFlex™ project atPauliström and it is clear that qualityhas improved. After the new press wasinstalled, testing by Metsä Tissueshowed that bulk had risen between 13and 22%, with the largest increasecoming on the lower-weight toiletgrades. In addition, the mill has alsoseen important improvements inabsorption properties of the sheet, aswell as uniformity and handfeel.

Prior to the installation of theTissueFlex™, the 2.7 m wide PM 6 hadtwo presses against the Yankee dryer.In the rebuild, the presses werereplaced with the TissueFlex™ pressroll against the Yankee. As was expect-ed, after-press dryness is clearly lowernow, compared to the time when themachine had two presses.

Eklund says that the TissueFlex™has been a big asset for developing newLambi (see sidebar page 11) qualities.

Getting value for money

Overall, it is clear that Metsä Tissuemade good investments in Småland bycarefully targeting new technology toproduce quality that consumers are will-ing to pay for. It has also been cautiousabout not buying more technology thanit really needs. In this manner, Andritz isa key partner in providing exactly theright solutions to help Metsä Tissuemeet these goals.

The people from the Småland regionof Sweden are famous for being verycareful with their money and resources.These investments in the Småland millsare an excellent example of how smalland simple can often be the most prof-itable strategy. ■

Holmen Paper's Hallsta mill in Hallstavik,Sweden started newsprint production in1915 and has now developed into oneof the world's largest and most modernproduction facilities for high qualitywood-containing printing papers. An-nual paper production capacity at themill has risen to nearly 800,000 tonnes.

During the past 20 years, Hallsta hasplaced increasing emphasis on movingup the value ladder. It has progressivelybeen making more improved newsprint,SC, and other specialty printing papers,while at the same time phasing outproduction of bulk grades.

As part of its multi-year, multi-millionEuro upgrading process, Hallsta recent-ly modernized numerous parts of themill to get better quality, output, andenvironmental efficiency. The center-piece of the latest round of investmentswas the enormous PM 11 which startedup in April 2002. This new machine, at 8.6 m trim width and capacity of330,000 t/a, is focused on MF maga-zine papers and improved newsprint.It replaced an older, smaller machineand created an increased demand forpulp on the order of 110,000 t/a.

To feed PM 11 and to meet theincreased pulp quality requirements,major investments were made in thewoodyard, TMP lines, and bleachingareas of the mill. Andritz played a keyrole at Hallsta by supplying majorpieces of equipment in each of theseareas for the modernizations.

H o l m e n P a p e r

Hallsta mill relies on RTSTM to raise TMP output while cutting energy costs

Andritz has worked very closely with Holmen Paper to get more output from their TMP 3 line through theaddition of two RTSTM refiners. The results have been excellent — energy savings of more than 300 kWh/tonneand improved quality. At the same time, the refiners gave a major boost in the line's production capacity.

Wood sorting for natural brightness

In 1999, Andritz supplied a new woodprocessing line to replace two olderlines, which were scrapped. The newAndritz line has a capacity of 3,300 m3

per day and consists of a log infeedsystem, debarking drum, and chipper.

The mill's woodyard plays a key rolein the drive for both product quality andenvironmental protection. Here, sprucelogs are sorted as they come into themill based on the annual growth ringsin the wood. In a method that Holmenhelped create in the mid-1990's, thisrough sorting is used to separate thewood into three categories. The fastestgrowing logs, with the highest annualgrowth increments, are used for thehighest brightness pulp.

In this manner, says Lennart Karlsson,Process Engineer at Hallsta, the millsaves on bleaching chemicals andreduces the environmental load. "As wemoved to improved grades with higherbrightness requirements, it seemed logi-cal to attempt to use the natural bright-ness of the wood," Karlsson says. "Sothe brightest chips are used for the high-est qualities, therefore saving bleachingchemicals and, of course, money."

TMP upgrade feeds PM 11

There are a total of four PMs being fedby four pulp lines. Three lines run TMP,and the oldest line, from the early1960's, runs stone groundwood.

Hallsta tries to focus its pulp lines sothat, essentially, one line feeds onepaper machine. TMP 3 is the one dedi-cated to PM 11. When the papermachine is running full speed (1850m/min), it consumes around 1,050 t/dof pulp. Before the rebuild, TMP 3 wasonly capable of making 700 tonnes perday. Clearly, something had to be doneto increase capacity.

Faced with this need to producemore pulp, Pulp Mill Manager MikaelWahlgren and his team looked at sever-al alternatives for adding pulp capacityto TMP 3. With energy costs rising inSweden, Wahlgren was also highlymotivated to reduce specific energycosts for the TMP. Andritz workedclosely with Hallsta to explore alterna-tives for modernizing TMP 3.

Energy savings from RTSTM refiners

Hallsta's TMP 3 is composed of fourparallel lines, each made up of one pri-mary and one secondary refiner. Theequipment, before the Andritz rebuild,was composed of old Jylhä refinersfrom the late 1980's. In the end, the milldecided to install two new Andritz RTSTM

refiners in the primary positions on twoof the lines.

"Essentially," says Wahlgren, "wewent with the Andritz RTSTM technologybecause it would save us energy.

An Andritz S 3068 replaced an old Jylhärefiner from the late 1980's. "It was a tightfit, but the Andritz refiners are compact.Saving space was an added advantage."

"We were guaranteed savings of at least300 kWh/tonne and that adds up to a lot ofmoney over the year." An Andritz RTSTM

refiner (model S 3068) connected to a 17MW motor operating at 2300 rpm.

The Andritz S 3068 refiner, with designcapacity of 285 t/d was operating at

350 t/d less than a year after start-up.

“We were guaranteed savings of at least300 kWh/tonne and that adds up to a lotof money over the year. The RTSTM wasalso a good solution because therefiners are rather compact. Since TMP3 is tightly packed into the building,saving space was an added advantage,"Wahlgren said.

The RTSTM concept is an Andritzdevelopment which adds a new dimen-sion to the conventional TMP process —refiner speed. The refiner plates turnat around 2300 rpm, versus 1500 rpmfor normal refiners. RTSTM raises thepreheating temperature at a controlledretention time to prevent lignin fromcoating the fibers. Pulp quality isimproved and the specific energy per tonof pulp produced is significantly reduced.

So far, says Wahlgren, the RTSTM refin-ers have worked very well, with energyconsumption well below the previouslevels and the pulp quality is excellent.

"We are saving 300 or more kWh pertonne and the pulp properties are asgood or better than with the oldrefiners. Light scattering, for example,is even better with the newRTSTM refiners," he said.

Savings higher than expected

Karlsson, the ProcessEngineer responsible for theTMP 3 line, was very involvedin the installation, start-up, andcontinuing optimization of theRTSTM refiners. "We are verysatisfied with the installation,"says Karlsson. "It has fulfilledall of the goals as far asquality is concerned and weare saving more energy thanAndritz guaranteed.We had been looking for 300 kWh/tonne and aresometimes getting 350 oreven more. We are usingaround 1,600 kWh, althoughthis varies depending on thewood quality."

Trials to test capacity

Capacity and throughput on the new linehave also been very good, with the millcontinuing to run trials to see just howmuch pulp the RTSTM units are capableof making. Micael Axelfelt, NorthernEuropean Sales Manager for Andritz,

works closely with the mill on thesecapacity trials. In fact, he has been work-ing very closely with the Hallsta team formore than 20 years, as he was a processengineer at the mill before joining Andritz.

The idea, says Axelfelt, is to put asmuch of the tonnage as possible throughthe low-energy RTSTM units, to gain bothenergy savings as well as improved pulpquality. In June 2003, the mill succeededin producing 15 t/h — the equivalent of360 t/d — during trials on the RTSTM line.The capacity of TMP 3 is now about 900 tonnes per day, with the disk filterbeing the bottleneck in the system.

All in all, the Hallsta team is verypleased with their choice of the AndritzRTSTM solution. With high quality pulp,produced at lower energy costs, feed-ing a new paper machine, it looks likeHallsta will remain a top player in themechanical printing paper markets for along time to come. ■

ASIP - Assist ^encia e Serviços para aIndústria do Papel, ACE, a special-purpose corporation owned byAndritz, Siemens, ATM, and Portucel,is responsible for the millwide main-tenance at Portucel's Setubal mill inPortugal.

This is part of Andritz's serviceconcept called Overall ProductionEfficiency (OPE®) where the goal is toincrease the production of a processline, or entire mill, by leveraging theoverall maintenance activities.

In the case of Setubal, the goal wasnot just to reduce maintenance costs,according to Henrique Figueira, Pulp andEnergy Production Manager. "Our firstpriority was to increase the availabilityof the installed equipment, through bettermaintenance approaches and state-of-the-art procedures. We are not interestedin saving money if, for instance, the avail-ability of the equipment decreases. Wewant to keep availability at a high level, atthe minimum cost."

Seppo Sandberg, Site Manager forASIP and also an Andritz employee,supports the logic to this approach.

"Maintenance cost per tonne of pulpis a key performance indicator,"Sandberg explains. "Each month wereport on the total maintenance cost pertonne of pulp produced. ASIP's com-pensation is based upon achieving keyperformance criteria (production, quali-ty, raw material consumption, safety,etc.) for each process area and overall.

"As the Site Manager, I have twosimple targets. The first is customersatisfaction. Without customer satisfac-tion, the second target is not achiev-able. The second target is a positivefinancial result for my company."

The drive for more production

Figueira says that the short-term goal isnot only to significantly reduce mainte-nance costs, but to increase production forthe same level of maintenance spending.This will reduce maintenance cost/tonne.The benchmark cost before ASIP beganwas 35 euros per tonne. Today's targetis 27 euros per tonne. "The drive is formore production at a higher equipmentavailability," Figueira says.

"Our first attempt at outsourcing localmaintenance began about eight yearsago in the woodyard area," Figueirasays. "We also did this for the effluenttreatment plant, but only small localcompanies were involved at that time."

The first major outsourcing contractPortucel made was for the Power area.They put the Power and Woodyard areastogether in one contract a couple ofyears ago and first selected another sup-plier to do the maintenance. Then themill awarded a Fiberline maintenancecontract to ASIP at the end of 2001.

"In March 2003, we made the deci-sion to consolidate all the local mainte-nance for the whole pulp mill into onecontract with ASIP, as we were satis-fied with what had been done in theFiberline area since January 2002,"Figueira says. Pulp production of themill is now 480,000 t/a.

"We needed a good, dedicated teamwith engineering backup," he continues."That's why we selected ASIP. Theyhave the knowledge, the procedures,and the team to achieve the goals wehave placed on ourselves."

Outsourcing — more than"labor brokers"

Portucel has had a good relationshipwith Andritz for years and was open todiscussions about new ways of doingmaintenance at a time when Andritz wasdeveloping its OPE® service concept.

"The OPE® concept here at Setubalis based upon using our processexpertise, our equipment knowledge,maintenance expertise from ourselvesand Siemens, and the expertise avail-able at the Setubal mill to form a part-nership," says Risto Hämäläinen, headof Pulp Mill Services for Andritz. "Thisis not simply labor outsourcing. We'readding as much value to the productionside as the maintenance side."

"ASIP has very professional people atour mill," Figueira says. "Process andequipment experts from Andritz andSiemens, their very best specialists fromAustria, Finland, and the USA visited themill to evaluate production performanceand conduct higher level process andtechnical studies in the fiberline, screen-ing, recovery, and pulp drying areas."

"This is one of the added values webring to the customer — our processexpertise," Hämäläinen adds. "This waspart of our initial proposal to Portucel inorder to distinguish OPE® from a con-ventional maintenance service. All ofour work, including the special studies,is designed to help Portucel get betterand more production out of this mill."

"Much of the main production equip-ment we have here is from AhlstromMachinery, which is now a part ofAndritz," Figueira says, "But, even if itweren’t Andritz equipment, I don't thinkthere would be any risk in gettingAndritz involved in an OPE program,due to the fact that they have theirbackground in process design, engi-neering, equipment design, and manu-facturing of the equipment used here."

"We are working with a very enlight-ened management at this mill and theyunderstand the role of maintenance in

reducing the overall cost of a producedtonne of pulp," Sandberg says.

The ASIP organization

ASIP consists of about 150 people andincludes people who used to workdirectly for Portucel.

For strategic reasons, Portucel con-tinues to staff the workshop and engi-neering functions inside Portucel. Theworkshops include the facilities insidethe mill and also some special shops

on the outside. Engineering is respon-sible for analyzing process equipment,supporting capital investments, andplanning for the annual shutdown.Portucel also maintains the spareparts stores.

"Our first and most important respon-sibility is the daily maintenance of themill," Sandberg explains. "As a part ofthis, we perform predictive maintenanceon equipment as we build the historicaldatabase about equipment perform-ance. When we began working here,we had no historical data to work from."

ASIP commits about 10 people inthe organization to various "engineer-ing" functions such as making improve-ment studies, investigating equipmentfailures and compiling fault reports.

Any shutdown longer than four hours isanalyzed in a Fault Report. Engineeringpersonnel analyze what happened, whatsteps were taken, and propose correctiveactions. The proposal indicates whatresources (ASIP, Portucel, third party,etc.) are required to correct the problem.

The goal is to provide higher avail-ability of the equipment at the same (or less) cost/tonne than Portucel haddone previously.

"Even though we wear different uni-forms, in the daily maintenance work

there is no difference betweenPortucel and ASIP people," Sandbergsays. "We work together very well.Perhaps one advantage for theemployee working for ASIP is thetraining we provide. Portucel evenpays a percentage of the costs sotheir own people can participate in ourtraining to keep updated on currentmaintenance procedures."

"I think it is a real challenge forASIP to take people who used towork for Portucel and organize thosepersons to handle all the requests formaintenance that the mill generates,"Figueira says. "Having the right skillsin the right place at the right time isnot easy."

Millwide results

"We have monthly reports about theavailability of each process area on a dailybasis (time stops) and production lossesin comparison with maximum sustainableproduction throughput," Figueira says.

Figures show that equipment availabili-ty is in general improved, together with anincrease in mill Capacity Efficiency (CE).

"Provided that the current perform-ance can be sustained, or even improvedin the near future at a reasonable cost,"Figueira says, "I can foresee this part-nership has the possibility to be devel-oped over a longer time."

At the end of the current three-yearcontract, Portucel and ASIP will sitdown to evaluate the overall activitiesand see if all partners have the com-mon interest to renew the contract peri-od. "There is still a lot that can bedone," Figueira says. ■

The Setubal Mill started up in

1964. First, batch digesters were uti-

lized to produce about 100,000 t/a of

bleached and unbleached eucalyptus

and Portuguese pine pulps.

In 1979, a complete pulp line with a

continuous digester was added and

production increased to 260,000 t/a of

fully bleached eucalyptus. In 1989, a

major modernization occurred, both

for quality and environmental reasons.

This included a new continuous

digester, a new recovery boiler, and

the closure of the 1964 pulping line.

The mill is located in the heart of

some natural preserve areas, so envi-

ronmental issues are very important.

Since 1995, the mill has been

de-bottlenecked and fine-tuning

operations were implemented (e.g.

increased evaporation capacity, modi-

fying one digester to expand the

cooking zone, etc.). Total output of

the pulp mill is now 480,000 t/a.

Shortly after the formation of itsFiber Preparation Division, Andritzwas awarded its first turnkey DeinkedPulp (DIP) line order by Vipap VidemKrsko Proizvodnja Papirja inCeluloze d.d., Krsko, Slovenia.

To say that Danijel Ostir and his teamat Vipap Videm Krsko, Slovenia were ina sticky situation in 1998 is an under-statement.

As Head of Technology and Develop-ment for this southeastern Europeanproducer of newsprint and packaginggrades, Ostir knew the mill's survivalwas at stake. Externally, the companyhad to endure Yugoslavia's civil warand a downward spiral for paperpricing. Internally, the mill's quality andenvironmental issues were, in Ostir'swords, "close to a catastrophe."

In rapid succession, Vipap VidemKrsko lost many customers who hadpurchased products for more than 20years. The company was also facingfines in the millions of euros because of high COD/BOD emissions into theSava River from their chemical pulpmill. The mill did not have the invest-ment capital to modernize this antiquat-ed pulping facility (bought secondhandin the 1970's) or rebuild their papermachines. Two small deinking unitsthey had recently installed were over-whelmed by stickies, resulting fromhigh amounts of glues and plastic wrapin the wastepaper furnish.

To add to the turmoil, the ownershipchanged, not once but twice, in 1998.The original owner, ICEC, a Czech pri-vate company, was bought by the IPBbank of the Czech Republic, whichthen sold the mill to CSOB, anotherCzech bank.

Moving toward a new beginning

Going back to the days of the originalowners, Ostir and his team analyzed andprepared over 40 options for a path for-ward. All of this was happening in thecontext of "consistently poor quality" pro-duction and countless hours trying toplacate customers who were threateningto throw Vipap Videm Krsko out for good.

With a grin today, Ostir can speak ofthese times as having a good side."We were fighting for our lives," hesays, "but we believed we could getthrough the mess."

But which was the right path forward?Says Ostir, "Basically, we proposed tomove from wood-free to wood-contain-ing newsprint, and still produce somegraphic paper. We knew that whateverwe produced, it would have to be con-stant quality and a competitive product."

In contrast, the mill's original ownersenvisioned production of a wide range ofnewsprint and graphic paper grades.Fortunately for Ostir and other VipapVidem Krsko managers, IPB, and thenCSOB, supported the plan they believedwould serve customers, shareholders,and employees best. They put the cen-tral focus on newsprint and improvednewsprint, increasing DIP and ground-

wood pulp production to a level thatwould replace chemical pulp completely.

This would offer management optionsfor raw material ratios and launch anapproach to raise environmental stan-dards even higher in some parametersthan those of the European Union (ofwhich Slovenia will become a member

on May 1, 2004). They could also closethe chemical pulp facility without losingany core customers.

Their pursuits are paying off. Sincethe fall of 2003, they have had a newdeinking plant with a capacity of160,000 t/a, and a rebuilt thermalgroundwood (TGW) plant of 50,000 t/aabout to come on-stream. In addition,two paper machines have been rebuiltto boost quality of news and improvednews, including installation of qualitycontrol and distributed control systems.Best of all — Vipap Videm Krsko hasseen the return of old customers, andorders from completely new customers.

Says Ostir, "The days of paying highfines because of pollution are over.That crippled our ability to make a prof-it. The new DIP line and, soon, ourrebuilt TGW plant give us a fresh start.The original catastrophe for sharehold-ers, employees, and the community ison the verge of being a big success.If there were a trophy for overcomingcatastrophe, we should win it."

Turnkey DIP from Andritz

Andritz's contribution to the Vipap VidemKrsko success is higher quality pulp,produced by the turnkey 400 t/d DIPline. The line started up in June 2003.

Andritz gives the mill the flexibility toachieve higher brightness with onlinebleaching. All design, engineering,equipment, instrumentation, tanks,chests, pipework/erection, start-upsupervision — even assistance secur-ing financing — came from Andritz.

Today, the headaches of stickies aregone, as the DIP line helps Vipap VidemKrsko consistently make standard andimproved newsprint, using ONP, OMG,and Mixed Office Waste as furnish.

According to Christian Pedratscher,Senior Vice President & DivisionalManager for Fiber Preparation Systemswith Andritz, "Vipap Videm Krsko nowhas the opportunity to purchase lessexpensive wastepaper, but run smooth-ly, and satisfy their customers."

Pedratscher points out that Andritzhas been in the recycled fiber prepara-

tion business for decades, but neverlike today. "Vipap Videm Krsko repre-sents the official beginning of our roleas a complete solutions supplier, com-bining the capabilities of the formerAhlstrom Machinery Corporation andAndritz, where we intend to grow ourmarket share. Our turnkey offering posi-tions us to win other orders where millsseek to maximize the value of waste-paper and lower costs."

Evident at Vipap Videm Krsko areAndritz's recent developments, notablythe SelectaFlot™ pre-/post-flotation cells,and the CompaDis™ dispersion system,which contribute to the quality of VipapVidem Krsko's complete line. In addition,the DIP plant includes the provenFibreFlow® Drum pulper, coarse and finescreens, thickening with screw pressesand disc filters, cleaner plants, HC per-oxide and MC dithionite post-bleaching,and the internal water treatment system.

The FibreFlow® Drum has a 3.5 minner diameter and a design capacity of 560 admt/d. The Drum producesstrong, clean pulp continuously, and

eliminates the need for separate de-trashing equipment. The gentle pulpingprocess produces high yields with mini-mal fiber damage.

Following the Drum are three stagesof coarse screening with ModuScreenC6R and C4R units. Hole size for thescreens is Ø 2.0 mm. The firstSelectaFlot™ unit, consisting of five pri-mary and two secondary cells is thenused for pre-flotation. The patentedMulti-Injector inside the SelectaFlot™cell creates optimal bubble size formaximum dirt speck removal and opti-mum brightness. The energy consump-tion is also about 20% less than com-parable cells, according to Pedratscher.

Following pre-flotation, four stages ofAhlCleaner TC 133 cleaners areemployed. Fine screening is accom-plished in a single ModuScreen HB7Runit, slot size 0.15 mm, and thickeningis accomplished with an Andritz DiscFilter and Screw Press.

After thickening, the CompaDis™ dis-perger combines heating and feeding inone advanced unit. The technology

SelectaFlot™ FibreFlow® Drum

was based on Andritz's long experiencewith HC refiners. Compared with otherdispergers, the design minimizes spacerequirements. A second SelectaFlot™unit, consisting of four primary and twosecondary cells, follows the dispergerin a post-flotation capacity. After thick-ening in another Disc Filter, the pulp issent to storage (for standard news) orMC Dithionite bleaching (for improvednews). Final brightness of improvednewsprint is about 65 ISO.

The irony of trouble starting with customers

The challenge of any deinking systemis to deal with problematic furnish. Theirony of the contaminant problem is thatthe mill's customers (printers) are oftenthe culprits in causing problems in themill's production. As printers use moreand more glue for binding, including hotmelt techniques, wastepaper is ladenwith materials that tend to agglomerateinto stickies — producing breaks, holes,

and many complaints when the paperhits a printing press.

The deinking system from Andritz hasdelivered a knockout punch to thisproblem. The other culprit, metalobjects from wire to staples, is alsoeliminated early.

Says Pedratscher, "Taking out allthe heavy contaminants in the begin-ning is essential so that they don'thave a chance to transfer problemsthroughout the process."

Even rejects now serve a useful pur-pose, combining with bark to becomeenergy in the mill's new biomass boiler.The deinked waste rejects, includingash and fibers embedded in the ink, goto sludge dewatering, are pressed to65% dry content, then are fed into thebiomass burner.

Thumbs up at the paper machine

According to Dragan Kranjc, ProductionManager for PM 1 & 2, the new deinked

pulp system and a rebuild of the wetend are producing positive results.

"Papermaking results are much bet-ter," Kranjc says. "We see fewer parti-cles in the sheet. Now we have fewerbreaks because of the new deinkingsystem, and rebuilding of the top wire,a new press section, and dryer section.”

Looking to the future

Vipap Videm Krsko is well-positionedwith options to produce quality paper ona consistent basis, meet or exceed envi-ronmental levels of the European Union,and have the flexibility to adjust the ratioof deinked to groundwood, based oncost and desired properties in the sheet.

What's ahead? Says Ostir, "Opti-mization, finding ways to make inferiorwaste perform at high levels, and cer-tainly no catastrophes!" ■
