Steam traps

Velan’s comprehensive range of steam traps is based on a uniquedesign that was developed and patented by A.K. Velan, CEO of Velan Inc., in the early 1950s. This unique product has been proven tohelp major refineries realize significant savings on their steam costs.

HF acid valvesAlkylation is the refiningprocess for chemically combining isobutene witholefin hydrocarbons throughthe control of temperatureand pressure in the pres-ence of an acid catalyst,usually sulfuric acid orhydroflouric acid.

The product, alkylate, hashigh octane value and isblended with motor oil oraviation oil to improve the"anti-knock" value of the fuel.

Hydrofluoric acid, one of thecatalysts used in this

process, is highly corrosiveand dangerous if leaked into the atmosphere.Consequently, this is a critical valve application and there are few manufac-turers with the appropriateexpertise.

There are two major licen-sors for HF alkylation serv-ice, ConocoPhillips and UOP.Velan manufactures forgedsteel and cast steel valvesfor both licenses and wehave installations all overthe world.

Metal-seated ball valvesVelan manufactures a widerange of severe service metal-seated ball valvesspecifically designed for therefining and petrochemicalindustries. Velan’s line ofcoker ball valves, whichincludes a multi-portedswitch valve has been successfully installed inover 90 delayed coker unitsworldwide. Applicationsrange from inlet transferlines to heater isolation.

Velan also manufactures a full line of metal-seatedvalves in sizes 1/2 –24”(15–600 mm) in ASME pressure classes 150–4500,and offers tight bidirectionalshut-off in the Securaseal®

product line. Applicationsrange from catalyst handlingto slurries and fly ash.

The refining process takescrude oil and separates itinto useable products.These products range fromlubricants to LPG, gasoline,kerosene, residual and distil-late fuels, coke, asphalt, solvents, and petrochemicalfeedstock.

The process overviewsThe refining process startswith fractionating, where thecrude is sent through twodistillation units. The firstunit is atmospheric distilla-tion, which separates andrecovers the lighter fractionsfrom the fresh crude oil.

The reduced crude feed is then sent to the second distillation unit, vacuum distillation, where light,medium, and heavy lubeoil is separated.

The separated crudes, now called feedstocks, are sent to different catalyticisomerization areas of theplant where they are treatedand further separated and“refined.”

During the Fluidized CatalyticCracking (FCC) process theoctane value is increased,and the feedstocks includinggas oil, coker gas oils, andFCC cycle oils are convertedinto high quality, low-sulfurfuels. Other processes forupgrading the quality of fuels

include hydrocracking,hydrodesulphurizationtreating, and coking.

One other area of the plant is gas separation, whichseparates the gas into lightcrude distillates and gas.

The gas plants use cryogen-ics to recover LPG fromrefinery and petrochemicaloff gases. Moderate recov-ery of ethane and high-purityhydrogen can also beachieved.

Refining production

The heart of every refinery isthe crude distillation unit. Ina crude unit, the oil is heatedand the different hydrocar-bon compounds are separat-ed by a process called distil-lation. “Distillation” meansthat, at different tempera-tures, the various hydrocar-bon compounds will “boil”

Atmospheric distillation and vacuum distillationoff and be separated fromthe feedstock. It is importantto note that the distillationprocess is the most commonprocess found in a refinery.Distillation towers are foundin almost every type of unitand are used to separate the various hydrocarbonfractions.

The atmospheric crude distil-lation tower is very tall andthe temperature in the towervaries from hot at the bottomto warm at the top. Lookingat the plant diagram, you willnotice that there are several“side draws” coming off thetower at various heights.

At these specific locations inthe tower, the temperature issuch that the desired prod-uct is separated from thecrude oil. At various heights(each with different tempera-tures) the different productsside draw during separation.Heavy products (such asasphalt) come off the bottomwhere the tower is thehottest, and lighter products(gas) come off the top whereit is only warm.

Crude units typically have anatmospheric and a vacuumdistillation tower. Using thevacuum distillation towerallows the refiner to “boil theoil” without raising the tem-perature up to the pointwhere coke will start to form.As a result, the refiner getsan additional output from theoil, before sending it down-stream to be processed further.

The cracking process plays avery important role in therefining of oil into fuel prod-ucts. Cracking is the breakingapart of long chains of car-bon molecules. The feed-stocks to crackers are“heavy” gas oil and “coker”gas oil. Both of these prod-ucts contain long carbonchain molecules. When theselong carbon chains are heat-ed to temperatures exceed-ing 680°F (360°C), they beginto break apart into lighter,more valuable products thatcan be used as fuels.

The purpose of cracking oil isto produce lighter productswithout producing coke, anatural by-product at hightemperatures. To limit andcontrol the formation of coke,which is a less valuableproduct that also lowers theefficiency of the process, acatalyst is used. The catalystsupplies energy to drive thereaction and therefore low-ers the required crackingtermperature and reducesthe formation of coke. Thetwo most common methodsused in the cracking processare fluidized catalytic crack-ing (FCC) and hydrocracking.

Catalytic crackingThe advantage of the FCCprocess is that the unit con-tinues to operate, which ispossible because the flu-idized catalyst bed can becontinuously circulated andregenerated. However,because the catalyst used isa fine abrasive powder that“circulates” through theprocess, abrasion can be aproblem for valves and otheroperating equipment.

Hydrocrackers are advanta-geous for two reasons. First,dirty and sour feedstockscan be “hydrotreated” priorto the cracking operation,which optimizes the processand produces a cleaner fin-ished product. Second, bycracking the “heavy” feed-stock in a hydrogen richenvironment, higher valuedlight end products are pro-duced. As in hydrotreaters,large amounts of hydrogenmust be compressed andrecycled into the process.Therefore, large compressorpackages are an integralpart of hydrocracking unitsand they are prime valveapplications.

Delayed cokingHot residual oil is fed to the base of the fractionatorwhere it mixes with the condensed recycle. Thecombined feed is heated inthe furnace until a suitabletemperature is achieved.Steam or boiler feedwater is injected into the heatertubes to prevent coking inthe furnace. The condensedrecycle joins the freshcharge, as mentioned earlier.The overhead stream is sentto a vapor recovery unitwhere the individual productstreams are separated. The wet gas and unstabilizednaphtha are sent to the lightends recovery plant for separation of fuel gas, LPG,and naphtha products.

The coke that forms in one ofthe parallel drums is removedusing high pressure water.The plant also includes a blowdown system, coke handling, and a water-recovery system.

ButadieneButadiene is a by-product ofethylene production. One ofthe largest commodity chem-icals produced in NorthAmerica is 1.3 butadiene.Butadiene may exist in either gas or liquid states.The most common method of butadiene production isthrough chemical extraction.This process uses an extrac-tion solvent such as acetoni-trile or dimethylformamide toproduce a pure butadienemonomer from a mixedbutenes stream.

Velan ball valves are anexcellent choice for butadi-ene service because of theirsuperior stem seal designand the wide range of seatmaterials that are availablefor different butadiene serv-ices. Related applicationswith similar problems wouldbe isoprene and styrene.

Petrochemical production

Olefin recoveryThe recovery of ethylene,propylene, and heavier components from refineryoffgas streams can beaccomplished with cryogen-ics, molecular sieve, or both. The refinery offgases fromthe catalytic crackers, cok-ers, or other sources are firsthydrated by molecular sievethen sent to an expanderthat compresses the gasstream. This gas stream isthen cooled through a heatexchanger. The recoveredethylene or propylene arethen feedstocks for thepetrochemical industry.

Olefins can also be dehydro-genated from paraffins usinga steam-active reformer.

Olefin by-productsMany products derived fromcrude oil refining, such as ethylene, propylene, butylene, and isobutylene,are primarily intended for

use as petrochemical feed-stock in the production ofplastics, synthetic fibers,synthetic rubbers, and other products.

AmmoniaAmmonia is another by-product of the refining indus-try and is very important inthe petrochemical industry.

Two raw materials are used to produce ammonia.Air supplies the nitrogen,and natural gas supplies the hydrogen for ammonia synthesis. Natural gas isreformed in a conversionreactor when it is combinedwith steam. Air is introducedto the second reactor at acontrolled rate to ensure theproper H2 to N2 ratio. Oxygenfrom the air is consumed inan exothermic combustionreaction while the inert nitrogen passes through the system.

In shift reactors 1 and 2 thewater-gas shift equilibriumreaction takes place as thetemperature of the steam islowered, combining thenitrogen and hydrogen

elements into NH3 - ammoniagas. The ammonia gas willthen be cooled and pressur-ized for storage or trans-portation as a liquid in

special ammonia storagetanks. The diagram above isa simplified illustration ofthis process.
