Sealing technology:A key component in the

operation of refineries.

Reliably safe and very economical

No industrial production plant can be operatedwithout seals. The number of sealing locations andmedia to be controlled is correspondingly large, as isthe number of plant components that need to besealed: rotating equipment such as pumps, agitatorsand compressors, valves and flanges, not to mentionpipes and ducts carrying gases and liquids.

The reliability of the entire plant depends on manyindividual parts. The seals, as key components, playan important role. They protect systems andcomponents from external influences andcontamination as well as help prevent emissions.They thus increase process safety, availability and theeconomic viability of the plant.

Sealing technology also offers considerable potentialfor reducing costs – through process-orientateddesign and standardization, for example. The rightproduct portfolio and knowledge of the processes andstandards used allows EagleBurgmann to implementsolutions that are not only technically safe andreliable but economically first-rate as well.

Pumping, transporting, and processing:The value-added chain in the hydrocarbonprocessing industry breaks down intothree main segments: upstream(exploration and production), midstream(transport and storage), and downstream(processing and refining). We havesignificant experience in all segmentsand can offer advanced sealing systemsand services to meet all technical,environmental, and economic

requirements.

Upstream and midstream processes

Oil and gas production offshore and onshore requiresdifferent technologies and equipment according to theoperating environment. Special pumps are used totransport multiphase flows of oil, gas, water and sand,after which they are isolated in separation facilities.The separated crude oil and gas is then sent for furtherprocessing to refineries.

Whether the work takes place on or off-shore,maximum safety combined with the longest possibleservice life and long maintenance intervals are theprimary requirements placed on sealing technology inthe oil and gas industry. Individually customized andoptimized sealing systems and expert know-how arethe determining factors in this respect.

Sealing technology in distillation processes:Demanding conditions - reliable solutions.

For distillation, the crude oil is first heated to around350 °C (662 °F) and then broken down intoindividual products. Substances with a boiling pointabove this temperature become gaseous and rise in

the distillation column.

High temperatures and different compositions ofcrude oils - which can also be corrosive (hydrogensulfide + sulfur) and abrasive - are some of thegreatest challenges faced by the sealing technologyused in refinery distillation facilities.

EagleBurgmann sealing systems have proven theiradded value over many years for sealing applicationsin both atmospheric and vacuum distillationprocesses. The portfolio of robust single and dual

mechanical seals with the necessary buffer, coolingand quench systems is optimized for distillationapplications.

We guarantee reliable sealing of the completeprocess chain in distillation facilities with our provenH75 and LL9 pusher seal types, while the MFLWTand MBS metal bellows seals are preferred for

particularly high temperatures. High quality slidingmaterials such as Buka 22 (a silicon carbidematerial) and structural materials from Inconel® areused for metal bellows.

EagleBurgmann offers perfectly customized supplysystems (to API 682 4th edition) to guaranteeoptimum operating conditions for the seals.Numerous operators around the world are applyingour sealing technology successfully in their processpumps and are profiting from the associatedincreased plant availability.

Cracking:Overcoming extreme temperatures

with “cool” sealing technology.

The fraction of crude oil which cannot be distilledfurther is then cracked. In this process, long chainmolecules are split into smaller molecules underpressure and temperature in order to generateadditional short-chain hydrocarbons such as gasoline,diesel or kerosene.

Different cracking methods with specific sealingrequirements are used, depending on the operator’srequirements.

Thermal cracking methods: steam cracking, visbreakingand coking are used to produce different products.While the starting mixture is heated to temperaturesbetween 370 °C (698 °F) and 460 °C (860 °F), thepressures remain below 15 bar (218 PSI).

Catalytic cracking methods: the fuel yield can beincreased to around 60 % with the aid of a zeolitecatalyst. Petroleum components, middle distillatesand gases are generated. Process temperatures canreach up to 500 °C (932 °F).

Hydrocracking methods: The most flexible method inrelation to the crude oil used and the productsgenerated is also the most cost-intensive due to thehigh hydrogen consumption. The operating conditionsrange between pressures of 70 … 200 bar (1,015 …2,900 PSI) and temperatures of 350 °C … 500 °C(662 °F … 932 °F).

The plant components and thus the sealingtechnology used must remain in operation, withoutinterruption, over long periods at extremely hightemperatures and pressures. Reliability andavailability are thus the decisive criteria.

EagleBurgmann supplies perfectly designed dualmechanical seals for sealing different hydrogensulfide (H

2S) concentrations in pumped media and

Gas processing:Sealing critical gases

without compromise.

Refinery gas occurs during distillation and post-processing of the crude oil. The gas mixture largelyconsists of methane, propane, butane and hydrogen.As it is contaminated with various substances, the

gas is cleaned in scrubbers and is often used forheating. Gas fractions that can be cost-effectivelyexploited, such as ethylene and propylene, areseparated and supplied to the petrochemical industry.

The significant rotating equipment in theseapplications are compressors, in addition to theprocess pumps.

Demands placed on the sealing technology are high.Extreme temperatures below -100 °C (-148 °F), highspeeds and pressures, media in the gaseous or liquidstate, combined with flammability and the risks thatthe gases pose to the environment demanduncompromising technology and sealing.

Our robust DGS and PDGS compressor seals haveestablished their position as the default solution inthe field of gas-lubricated mechanical seals forcritical gases such as oxygen, hydrogen or carbon

dioxide. We largely apply pusher type H75 and LL9UCmechanical seals to seal process pumps, while ourMFL and MBS682 series metal bellows seals haveproven their value in cryogenic processes.

Liquid hydrocarbons:Safe sealing technology for

explosive mixtures.

The hydrocarbons occurring within the refineryare further treated in various processes according torequirements for special end products andcomposition.

For example, the reforming process serves toincrease the octane rating of the gasoline which -untreated - has a very low knock resistance(40 ... 60) and is thus unsuitable for modern enginesthat need 91 ... 98 octane fuels. To this end,naphthene is converted by dehydration andisomerization into aromatics with high octane ratings.The reactions take place at between 450 °C …550 °C (842 °F … 1,022 °F) and under pressuresranging from 15 … 60 bar (218 … 870 PSI).

The base oil also cannot be used straight away tomanufacture engine oil because of its properties.The aromatics need to be removed first, then theparaffin wax is extracted. The final step is to remove

impurities.

The sealing of flammable and explosive mediamixtures (in compliance with the German TechnicalInstructions on Clean Air Control (TA-Luft) and theATEX guidelines is one of the biggest challengesfacing sealing technology in these processes.

Mature, standardized mechanical seal solutions(types H75, LL9UC, MFL and LY) have proven theiradded value all around the world for all kinds ofprocess pumps.

We offer durable EagleBurgmann expansion joints forpipeline systems and ducts carrying liquids andgases. For reliably sealing flanges, Spiraltherm spiralwound and Corratherm corrugated gaskets aresuccessfully applied seal solutions in numerous areasof the refinery.

Heavy hydrocarbons:Simple solutions - with the right seal.

Heavy hydrocarbons such as bitumen from thevacuum distillation process and thermal crackingmethods are converted into gases, fuels, middledistillates and pet coke in the coker unit. The starting

product is first heated to around 500 °C (932 °F),cracking the long-chain hydrocarbons into shortchains. Considerable quantities of saleable coke areproduced as a by-product of this process.

High process temperatures required by the process,due to the high solidifying points, combined with theextremely contaminated media, are the mainchallenges for the mechanical seal technology.

Technically mature MFLWT and Y9 high-temperaturemetal bellows seals and suitably designedEagleBurgmann supply systems have been mostsuccessful in this challenging environment.

On the other hand, EagleBurgmann packings andpacking cartridge units type 9984 significantlycontribute to increased throughput in refineriesworld-wide. As a critical process component inhydraulic decoking systems the packing cartridgeshelp to increase life time and productivity of the unit.

EagleBurgmann BuraTAL-Flex 6070 low-emissionvalve packings have been approved as the standardpacking in refineries. They meet even strictestenvironmental regulations (e.g. API 622 and

API 589).

Consulting & Engineering

After establishing and analyzing all of the installedseals in a system, we develop standardizationconcepts based on the “as-is” status. The resultswe strive for are to reduce the number of sealtypes, sizes and materials used and to improve theplant performance of the system. We advise you oncodes of practice and statutory regulations andindicate what actions need to be taken.

Maintenance

In the plant or in the service center, qualifiedfitters and technicians look after all the aspectsof seal maintenance – installation, start-up,servicing, conversion, overhaul and repair. Werecord and document functionally relevant data(failure reasons and related cost s). This meansit is possible to evaluate seal operat ing timesand maintenance costs on a continuous basis ,thereby defining measures for extending serviceintervals.

On-site Service

Our on-site service includes the components ofan overhaul service, conversions and servicecontainer. We deploy a service unit directly toyour premises: equipped with the basic range ofseals or a stock of seals discussed with you inadvance and staffed by qualified personnel. On-site,we assure production of the necessary gaskets,ensure that the documentation is complete andadvise our customers on the selection and

installation of seals. Our range of services alsoincludes complete conversions (e.g. acc. to TA-Luft).

Inventory Management

Based on your individual requirements and theapplicable quality regulations, we developa concept for inventory management ofcomplete seals and spare parts. Furthermore, weoptimize stocking on-site or in theEagleBurgmann service center. In this way, you

reduce your administration overhead andconcentrate on your key operations.

Seminars & Training

We offer an extensive range of conti nuingeducation programs in sealing technology,developed for service and maintenance personnel,and skilled staff and engineers from variousbranches of industry including refining, chemical,power generation, foodstuffs, paper andpharmaceutical. Our program includes groupseminars, individual training and seminarsspecifically tailored to your requirements held atour premises or at a location of your choice.

Technical Analysis & Support

A team of seal specialists i s responsible forrectifying process malfunctions or “bad actors”.The latest methods, such as thermography ordata logging, are used for diagnosing criticalitems for the operation of the plant and fordefining measures to resolv e them. In ourresearch and development centers, we performrealistic tests on test rigs or in original pumps.The objective is to extend the MTBF and toincrease system reliability by individual andconstructive solutions.

Service Agreements

We offer our customers specific agreementsthat are combined from the six service modules.Whether for individual seal systems, criticalprocess elements, specific plant units or anextensive seal service for complete plants, themodular structure of our service makes it possible

to satisfy individual requirements. With our wellestablished monitoring instrument, SEPRO, wecan also record all seal-related data fordocumentation and evaluation purposes.
