Project Shuaiba, Paraxylene Unit (Licensor UOP), 768000 t/year. Project Shuaiba, Benzen Extraction Unit (Licensor UOP), 325000 t/year. Shuaiba processing flows designed to produce high purity para-xylene and benzene from a naphtha feedstock, with ortho-xylene as a co-product, contains a number of processing steps where the naphtha is first hydrotreated and then fed to the CCR Platforming Process unit to produce aromatic stream rich in benzene, toluene, and C8 and heavier aromatic compounds.

The CCR Platforming process produces aromatics from naphthenes and paraffins. The feed naphtha is generally restricted to C6 through C9 compounds to maximize the production of benzene, toluene, and xylenes. Four major reactions occur in the reactors to produce the desired products: dehydrocyclization of paraffins to 5-membered rings; isomerization of 5-membered to 6-membered rings; dehydrogenation of 6-membered rings to aromatics; hydrocracking of large hydrocarbons to smaller hydrocarbons. The function of the reformer is to efficiently convert paraffins and naphthenes to aromatics with as little ring opening or cracking as possible.

The Sulphfolane process combines liquid-liquid extraction with extractive distillation to recover high purity aromatics from hydrocarbon mixtures. Because of the large difference in boiling point between the sulpholane solvent and the

heaviest aromatic component, this separation is accomplished easily, with minimal energy input. To minimize solvent temperatures, the recovery column is operated under vacuum.

The Tatoray process is used to selectively convert toluene and C9 aromatics into benzene and xylenes. The two major reactions in the Tatoray process are disproportionation and transalkylation. The conversion of toluene into benzene and xylenes is called toluene disproportionation. Transalkylation is the conversion of a mixture of toluene and A9 into

xylenes. The Tatoray process uses a very simple flow scheme consisting of a fixed bed reactor and a product separation section.

The Parex process provides an efficient means of recovering para-xylene using a solid zeolitic adsorbent which is selective for para-xylene.The Parex unit has 24 adsorbent beds with 26 sets of chamber internals, and 24 bed lines connecting the beds to the rotary valve .Parex units consist of two adsorption chambers in series with 12 beds each. In the Parex process, there are four major streams that are distributed to the adsorbent chamber by the rotary valve. These ‘net’ streams include: a) feed in (mixed xylenes feed); b) dilute extract out (para-xylene product diluted with desorbent); c) dilute raffinate out (ethylbenzene, meta- and ortho-xylene diluted with desorbent); d) desorbent in (recycle desorbent from the fractionation section). The rotary valve is used to periodically switch the positions of the liquid feed and withdrawal points as the composition profile moves down the chamber.

The Isomar process is used to maximize the recovery of a particular xylene isomer from a mixture of C8 aromatic isomers. C8 aromatic reactor fed, deficient in one or more component relative to equilibrium composition, is processed over a fixed bed of catalyst in the presence of hydrogen. The liquid portion of the effluent is fractionated to remove both light and heavy aromatic by-products as well as the cracked materials resulting from inclusion of saturates in the feed. Para-xylene and/or ortho –xylene are separated from the resulting fractionation hear-cut, thereby preparing a recycle material to the ISOMAR rector. Fresh feedstock is introduced into the circuit in the most appropriate place.

CDU& VDU, Gasoline Hydrofining Unit, Process Engineer

Process Objective to distill and separate valuable distillates (naphtha, kerosene and diesel) and atmospheric gas oil (AGO) from the crude feedstock.

Process steps are: 1) Preheat the crude feed utilizing recovered heat from the product streams. 2) Desalt and dehydrate the crude using electrostatic enhanced liquid/liquid separation (Desalter). 3) Heat the crude to the desired temperature using fired heaters. 4) Flash the crude in the atmospheric distillation column. 5) Utilize pump around cooling loops to create internal liquid reflux. 6) Product draws are on the top, sides, and bottom.

Objective of VDU process is to recover valuable gas oils from reduced crude via vacuum distillation by reducing the hydrocarbon partial pressure and stripping steam.

Process steps are: Heat the reduced crude to the desired temperature using fired heaters. Flash the reduced crude in the vacuum distillation column. Utilized pump around cooling loops to create internal liquid reflux. Product draws are top, sides, and bottom.

Steaua-Romana Campina, Oil Refinery Romania 2000-2003

Process Engineer, Diesel Hydrofining Unit

This unit used to remove contaminants (sulfur, nitrogen, metals) and saturate olefins and aromatics to produce a clean product for further processing or finished product sales.

Process steps are: Feed is preheated using the reactor effluent. After that hydrogen is combined with the feed and heated to the desired hydro treating temperature using a fired heater. Feed and hydrogen pass downward in a hydrogenation reactor packed with various types of catalyst depending upon reactions desired. Reactor effluent is cooled and enter the high pressure separator which separates the liquid hydrocarbon from the hydrogen/hydrogen sulfide/ammonia gas. Acid gases are absorbed from the hydrogen in the amine absorber. Hydrogen, minus purges, is recycled with make-up hydrogen. Further separation of LPG gases occurs in the low pressure separator prior to sending the hydrocarbon liquids to fractionation.
