1.0 INTRODUCTION
Piping study for the column should start after complete understanding of the followingdocument:
a) Technical specification of the columnb) P&IDc) Unit Plot Pland) Basic Engineering document highlighting the specific process requirement, platform
requirement and guidelines for the general arrangement of piping around the column.e) Details of internal arrangements e.g.
for packed type - the packing height, packing support and manhole / hand hole locations,and for tray type - the nos. of tray, type of tray, downcomer location, manhole location etc.
f) Instrument data sheet.g) Line list with operating / design conditions of the fluid.
1.1 Some understanding of the process function will facilitate the piping study to meet therequirements of operation, maintenance, safety and the aesthetics. Various types of columnwith their varying functions are in use for refinery and Petrochemical industry.
Generally they are distinguished based on the specific operation for mass transfer viz.Distillation, Absorption - stripping or Fractionation etc.
2.0 DISTILLATION
The distillation is separation of the constituents of a liquid mixture via partial vaporisation of themixture and separate recovery of vapour and residue.
Various kinds of devices called plates or trays are used to bring the two phases into intimatecontact. The trays are stacked one above the other and enclosed in a cylindrical shell to form acolumn.
The feed material, which is to be separated into fractions, is introduced at one or more pointsalong the column shell. Due to difference in gravity between liquid and vapour phases, theliquid runs down the column, cascading from tray to tray, while vapour goes up the columncontacting the liquid at each tray.
The liquid reaching the bottom of the column is partially vaporised in a heated reboiler toprovide reboil vapour , which is sent back up the column. The remainder of the bottom liquid iswithdrawn as the bottom product.
The vapour reaching the top of column is cooled and condensed to a liquid in the overheadcondenser. Part of this liquid is returned to the column as reflux to provide liquid overflow andto control the temperature of the fluids in the upper portion of the tower. The remainder of theoverhead stream is withdrawn as the overhead or distillate product.
The Typical distillation process tower is illustrated in Fig.CLP-1 and crude distillation ofproducts across temperature range is illustrated in Fig.CLP-2.

2.1 ABSORPTION AND STRIPPING
Many operations in petrochemical plants require the absorption of components from gasstreams into lean oils or solvents. The resultant rich oil is then stripped or denuded of theabsorbed materials. The greatest use of this operation utilises hydrocarbon materials, but theprinciples are applicable to other systems provided adequate equilibrium data is available.
A typical flow diagram of absorption-stripping system for hydrocarbon recovery from gaseousmixture is illustrated in Fig. CLP-3.
2.2 FRACTIONATION
A fractionation column is a type of still. A simple still starts with mixed liquids, such as alcoholand water produced by fermenting grain etc. and by boiling produces a distillate in which theconcentration of alcohol is many times higher than in feed. In petroleum industry, mixtures ofnot only two but a lot many components are dealt with. Crude oil is a typical feed for afractionation column and from it, the column can form simultaneously several distillates such aswax distillate, gas oil, heating oil, naptha and fuel gas. These fractions are termed cuts.
The feed is heated in a furnace before it enters the column. As the feed enters the column,quantities of vapour are given off by flashing due to release of pressure on the feed.
As the vapours rise up the column, they come into intimate contact with down flowing liquid.During this contact, some of the heavier components of the vapour are condensed and some ofthe higher components of the down flowing liquid are vaporised. This process is termedrefluxing.
If the composition of the feed remains the same and the column is kept in steady operation, atemperature distribution establishes in the column. The temperature at any tray is the boilingpoint of the liquid on the tray. 'Cuts' are not taken from every tray. The P&ID will show cuts thatare to be made, including alternatives. Nozzles on selected trays are piped and nozzles foralternate operation are provided with line blinds or valves.
The fractionator tower is illustrated in Fig.CPL-4.
The typical vacuum tower and stripper is illustrated in Fig.CLP-5. Stripper is used to striplighter materials from bottom of a main or a vacuum tower distilling crude bottom residue undervacuum.
2.3 INTERNALS
Columns based on internal details are often called as either Plate Columns or PackedColumns.
Plate Column:The lighter hydrocarbons vaporise and flow up through the holes in the tray plate, makingcontact with the liquids on that tray.
Tray types are: Bubble Cap trays, Valve trays, Sieve trays
Bubble Cap Trays: Bubbling action effects contact. Vapour rises up through 'risers' intobubble cap, out through slots as bubbles into surrounding liquid on tray. Liquid flow over caps,outlet weir and downcomer to tray below.

Valve Trays: Commonly used valve trays are stamped out by big press and these trays comewith small valves attached to them which allow vapour traffic.
Sieve Trays: Sieve trays are perforated flat plates. They are inexpensive for small diametervessels but large diameter towers must have extensive supports for these trays. Sieve traysare used for heavy hydrocarbon fractionation.
All trays have foam on top of liquid. The height of the foam will vary with the process. Foammay rise a foot or more above the tray liquid.
Liquid-gas contacting is made effective through the above trays by cross-flow or counter flow.In counter flow plates, liquid and gas utilise the same openings for flow, thus there are nodowncomers.
Perforated plate with liquid cross flow (sieve plate) is the commonly specified tray.These two types of flow is illustrated in Fig.CLP - 8.
The two most commonly used types of tower viz. the trayed and packed arrangements areillustrated in Fig.CLP-6 and Fig.CLP-7 respectively.

A typical plan of equipments located in the refinery type of plants highlighting the maintenanceaccess is illustrated in Fig.CLP-32.
3.5 Instrument standard shows:• The location of instrument connections to tower for gauges, level controllers and level
alarms.• Location of pressure and temperature connections without orientation.• The instrumentation systems around the tower are depicted in the P&ID.
3.6 Fabrication drawing / detail dimensional drg. of column provides :• Diameter and height of column.• Details and dimensions of internals.• Manhole• Process-piping connections in elevation (without orientation)• Drum, pump, exchanger drawings giving details of adjacent process equipment or
equipment supported on column itself.
An integrated piping study should be developed from the above information.
The piping study should take care of all the general recommendations of piping arrangementaround the column and its related equipment and facilities as illustrated in Fig.CLP-25"Typical arrangement of external piping around column"
4.0 SEQUENCE OF COLUMN PIPING STUDY
4.1 All available information / data from Equipment specification and P&ID shall be written on theelevation view of the column as illustrated in Fig.CLP-12, CLP-13 & CLP-15.
4.2 The designer now starts thinking about the proper orientation of nozzles and provisions foraccess to the points of operation and maintenance.
4.3 Considerations of the pipeline leaving the tower area and the adjacent piping shall bevisualised.
4.4 The first step is to orient the manholes preferably all in same directions. Normally, manholesshall be oriented towards dropout area within a 30° segment of column as this facilitates thelowering of tower internals to the main access way. The manhole segment of platform shouldnot be occupied by any piperack.
4.5 A break in ladder rise (normal 5m, maximum 7m) will occupy another segment of column forplatform.
4.6 The levels of platforms are to be decided on the elevation view based on the manholes andaccess to relief valves, instrument for viewing.
4.7 All platform levels in the proper segments of the tower with ladder location should be drawn onplan view. The manhole shall be shown in proper segment with the angle of orientation, andthe space for the swing of manhole cover taking davit hinge as centre.
4.8 Layout should be started from the top of the column with the designer visualising the layout as awhole. There will be no difficulty in dropping large overhead line straight down the side of acolumn, and leaves the column at a high level and crosses directly to the condenser. Thisclears a segment at lower elevations for piping or for a ladder from grade level to the firstplatform.

4.9 Flexibility and thermal load connected with the large-dia overhead lines to the condenser atgrade level or higher level shall be considered. The relief valve protecting the tower is usuallyconnected to the overhead line. A relief valve discharging to atmosphere should be located onthe highest tower platform.
In a closed relief-line system, the relief-valve should be located on the lowest tower platformabove the relief -system header. This will result in the shortest relief-valve discharge leads tothe flare header. The entire relief-line system should be self-draining.
4.10 From layout point of view, it is preferable to space the platform brackets on the tower equallyand to align the brackets over each other for the entire length of the tower. This will minimiseinterferences between piping and structural members.
4.11 Nozzles and piping must meet process requirements while platforms must satisfy maintenanceand operating needs. Access for tower piping, valves and instruments influence placement ofladders.
4.12 In routing pipelines, the problem is faced to interconnected tower nozzles with other remotepoints. The tentative orientation of a given tower nozzle is on the line between tower centre andthe point to which the line is supposed to run. Segments for piping going to equipment at gradee.g. condenser and reboiler lines are available between ladders and both sides of manhole.See the Fig. CLP-21 / 31 for overall orientation of a distillation column.Line approaching the yard/piperack can turn left or right depending on the overall arrangementof the plant. The respective segments of these lines are between the ladders and 180°. Thesegment at 180° is convenient for lines without valves and instruments, because this is thepoint farthest from manhole platforms.
The sequence of lines around the tower is influenced by conditions at grade level. Pipingarrangements without lines crossing over each other give a neat appearance and usually amore convenient installation.
4.13 The correct relationship between process nozzles and tower internals is very important. Anangle is usually chosen between the radial centreline of internals and tower-shell centrelines.By proper choice of this angle (usually 45° or 90° to the piperack) many hours of work andfuture inconvenience can be saved. Tower piping, simplicity of internal piping and manholesaccess into the tower are affected by this angle. After this, the information produced by thedesigner results in selecting the correct orientation of tower nozzles.
4.14 A davit usually handles heavy equipment such as large-size relief valves and large-diameterblinds. If the davit is at the top of the tower, it can also serve for lifting and lowering towerinternals to grade.Clearance for the lifting tackle to all points from which handling is required, and good accessshould be provided.
4.15 Very often, interpretation of process requirements inside a tower is more exact than for exteriorpiping design. The location of an internal part determines, within strict physical limits, thelocation of tower nozzles, instruments, piping and the steelwork. The layout designer have toconcentrate on a large-scale drawing of tower-internal details and arrangement of processpiping to finalise the piping study.
4.16 Access, whether internal or external is very important. This includes accessibility ofconnections from ladders and platforms and internal accessibility through shell manholes,handholes or removable sections of trays. A manhole openings must not be obstructed byinternal piping.

4.17 Reboiler-line elevations are determined by the draw off and return nozzles and their orientationis influenced by thermal flexibility considerations. Reboiler lines and the overhead lines shouldbe as simple and direct as possible.
4.18 Fig.CLP-23 shows the segments of tower circumference allotted to piping, nozzles, manholes,platform brackets and ladders as normally recommended to develop a well-designed layout.
5.0 NOZZLE ORIENTATION AND LEVEL
Nozzles are located at various levels on the tower to meet the process and intstrumentationrequirements.
5.1 MANHOLES
Nozzles are to be oriented keeping provision for maintenance and operation needs.
Manholes are usually located at bottom, top and intermediate sections of tower. Theseaccess nozzles must not be located at the downcomer sections of the tower or the seal potsections of the tower.
Where internal piping is arranged over a tray, manhole shall be provided but it should beensured that the internals do not block the maintenance access through the manhole.
Possible location of manhole and handholes within the angular limits of b° are illustrated indetail-2 of Fig.CLP-21
5.2 REBOILER CONNECTIONS
Reboiler connections are normally located at the bottom section of the tower. Detail-1 ofFig.CLP-21 shows reboiler draw-off connections for single-flow tray. This connection can bevery important for arranging tray orientation. The simplest, most economical location forreboiler connections with the alternative location within the angular limits of a° is shown. Theangle a° depends on the size of reboiler draw off nozzle and the width of the boot(dimension 'b') at the tray down flow.
The return connection from the thermosyphon reboilers is shown in detail-1 of Fig.CLP-21.These lines should be as simple and as direct as possible, consistant with the requirements ofthermal flexibility.
For horizontally mounted thermosyphon reboiler, the draw off nozzle is located just below thebottom tray and for vertically mounted recirculating thermosyphon reboiler, the draw offnozzle is located at the bottom head. For both the systems, the return nozzles are locatedjust above the liquid level as shown in Fig.CLP-33.
5.3 REFLUX CONNECTIONS
Reflux nozzles are provided with internal pipes that discharge the liquid into the sealpot of thetray below. Detail 3 of Fig.CLP-21 shows the reflux connections. Care must be taken thatthe horizontal leg of the internal pipe clears the tops of bubble caps or weirs. It must beensured that the internal pipe can be fabricated for easy removal through a manhole or canbe fabricated inside the tower shell.

5.4 OVERHEAD CONNECTIONS
The vapour outlet nozzle is usually a vertical nozzle on the top head of tower. In addition, thevent and relief valve could be located on the top head with a typical platform arrangement foraccess to vent, instrument connections and top manhole. In a closed relief line system, reliefvalve should be located on the lowest tower platform above the relief system header. This willresult in the shortest relief valve discharge leads. The entire relief line system should be selfdraining.
5.5 BOTTOM CONNECTIONS
The liquid outlet is located on the bottom head of the tower. If the tower is supported on skirt,the nozzle is routed outside the skirt as shown in Fig.CLP-22. The elevation and orientationof this line is generally dictated by the pump NPSH requirement and the pump suction lineflexibility. (see Fig.CLP-30)
5.6 TEMPERATURE & PRESSURE INSTRUMENT CONNECTIONS / LEVEL INSTRUMENTS
The temperature and pressure instrument connections are located throughout the tower. Thetemperature probe must be located in a liquid space and the pressure connection in a vapourspace as shown in Fig.CLP 37.
The level instruments are located in the liquid section of the tower usually at the bottom. Theelevation of the nozzles is decided by the amount of liquid being controlled or measured andby standard controller and guage glass lengths. Level controllers must be operable fromgrade or platform and level guages / switches may be from a ladder if no platform is available.Fig.CLP-35, 36, 37, 38, 39 illustrates a few instrument connections on tower.
6.0 ACCESS AND MAINTENANCE FACILITY
6.1 Access whether internal or external is very important. This includes accessibility ofconnections from ladders and platforms and internal accessibility through shell manholes,handholes or removable sections of trays.
6.2 Tower maintenance is usually limited to removal of exterior items (e.g. relief or control valves)and interior components (e.g. trays or packing rings) Handling of these items is achieved byfixed devices (e.g. davits or trolley beams) or by mobile equipment (e.g. cranes). Whendavits or beams are used, they are located at the top of the tower, accessible from a platformand designed to lower the heaviest removable item to a specific drop out area at grade level.When mobile equipment is used, a clear space must be provided at the back (side opposite topiperack) of the tower that is accessible from plant auxiliary road.
Fig.CLP-16, 25, 29, 32 illustrates the access and maintenance facilities to be considered inthe piping arrangement around a tower.
On free-standing columns, access for major maintenance to insulation or painting will usuallyrequire the erection of temporary scaffolding. Space for scaffolding at grade level andprovision of cleats on the shell to facilitate scaffold erection should be considered.
6.3 Utility stations of two services viz. steam and air are usually provided on maintenance platforms.Steam and air risers should be located during piping study to keep adequate cleats for support.(see Fig.CLP-20)

7.0 PLATFORMS AND LADDERS
7.1 Platforms on towers are required for access to valves, instruments, blinds and maintenanceaccesses. Platforms are normally circular and supported by brackets attached to the side ofthe tower. Generally, access to platforms is by ladder. Fig.CLP-19 illustrates the platformrequirements.
7.2 Platform elevations for towers are set by the items that require operation and maintenance.The maximum ladder run should not exceed 7m.
7.3 Platform widths are dictated by operator access. The clear space on platform width shall bemin.900mm.
For platforms with control stations, the width of platform shall be 900mm plus the width ofcontrol station.
The platform for manholes and maintenance access, adequate space for swing the coverflange flange must be provided.
7.4 Top-head platforms for access to vents, instruments and relief valves are supported on headby trunions.
7.5 Access between towers may be connected by common platforming.
7.6 It is preferrable to space platform brackets on tower equally and to align brackets over eachother over the entire length of shell. This minimises the structural design and interferencesfrom piping.
7.7 On very wide platforms or those that support heavy piping loads, knee bracing is required inaddition to the usual platform steel. The potential obstruction immediately under the kneebrace must be kept in mind during platform design.
7.8 Fig.CLP 15, 16, 17, 18, 19, 20 illustrates a few platform considerations.
