N e w Entry in Aromatic Sweepstakes Petrochemical b a n z e n e , t o l u e n e , and
plant adds 5 3 million gallons of xylenes to country's a n n u a l supply
A NEW addition was made this month ^ to the nation's fast-growing petrochemicals industry when Sun Oil officially opened its $15 million installation at Marcus Hook, Pa. Plant has been designed to produce 19 million gallons of benzene, 19 million gallons of toluene, and 15 million ga.lions of mixed xylenes a year. Although part of tbe plant is now on stream, the operation will not b e entirely under way until the end of the month. Siarnilar to plants elsewhere in the U. S., t h e new installation is unique for this particular area of the country. Sun Oil's operation uses three basic processing steps, all of which are run continuously. First involves fractionation of selected stocks from crude oil and natural gas. Second is a reforming step in which various naphthenes are converted to benzene, toluerae, and xylenes. Final step involves tlae separation of these products. At the start of the process, S28,700 barrels per month of straight-ruin gasoline are fed into the depemtanizer (see flowsheet). High-boiling fraction goes to another distillation column, where the feed stock for production of benzene and toluene is distilled overhead. This stream already contains a small amount of benzene and toluene nat5174
In this prefractionation section, feed stock is prepared before charging to the Houdriformer where benzene, toluene, and xylenes are formed over platinum catalyst cyclohexane, and dirxietliylcyclopentanes, which are catalytically converted to benzene and toluene in the Hoixdriformer. In this reaction, operated at over 900° F . and 3O0 pounds per square inch pressure arid employing a platinum catalyst, the cyclohexane and methylcyclopentane a r e converted, to benzene and hydrogen^ A t trie same time methylcyclohexane and dixnethylcyclopentanes are converted to -toluene.

million cubic feet per day of hydrogen is produced as a by-product, part of which is withdrawn and the remainder continuously recycled to prevent catalyst deactivation. As a result of this hydiogen recycling, the catalyst never has to be regenerated and thus is kept continuously on stream. After separation of hydrogen and pentane, product undergoes extraction 3y the Udex process, licensed from Universal Oil Products. I n the Udex extractor, the product, rich in benzene ind toluene, flows countercurrently to i diethylene glycol solution. Glycol
removes benzene and toluene from the contaminating hydrocarbons. In a second tower, the products are separated from glycol by distillation, and glycol is pumped back to the extractor for re-use. After passage through a clay treater for removal of impurities, aromatics are distilled for separate recovery of nitration-grade benzene and toluene. Xylene Production.

clohexane, and trimethylcyclopentane, which can be converted t o xylenes. This xylene feed stock is p r e p a r e d continuously but is stored while the Houdriformer is producing benzene and toluene. Similarly, the benzene-toluene feed is stored while the Houdriformer is used in the production of xylenes. The synthesis of xylene is similar to that of benzene and toluene, although a higher pressure—500 pounds per square inch—is required. Again, over 13 million cubic feet of hydrogen is produced per day. T h e product from the reformer is fed to t w o distillation towers in series, one of w h i c h recovers a light gasoline and the other a naphtha stream. A third tower separates the final xylene product from a small amount of higher-boiling aromatics. The xylenes can be recovered merely by fractionation rather t h a n by more elaborate process used in the recovery of benzene and toluene. This is possible since t h e feed to the Houdriformer contains virtually nothing boiling above 265° F. Since the lowest boiling xylene boils at about 277° F., it is possible to fractionate the xylenes from the unconverted portion of the feed. The new plant, which circulates about 170,000 barrels of materials a day, not including 44,000 gallons per minute of cooling water, has been designed with a high degree of ~exibility. As a result, the relative proportions of the three major products can b e widely varied depending on market demand. In fact, the plant can also b e used for increasing the octane number of motor gasoline or for t h e production of aviation gasoline blending stocks. 5175

N.Y ShawirJgan Plans Bu+yral Expansion Shavvinigan Resins plan, to expand production of one of its basic resins— polyvinyl butyral—for the second time in less than a year. Capacity increase will enable the plant to meet the demand anticipated for the next three years. T h e new program will boost capacity about 20%. A 3 5 % hike, announced last April, was completed recently. In making the decision to expand beyond current demand, Shavvinigan is taking a leaf out of the book of its biggest customer, the automotive industry. New capacity may b e on standby basis at times, but it also will be able to fill the cyclical peak needs of the automobile industry for safety glass. Heyden Completes Antibiotics Sale to American C y a n a m i d Heyden Chemical completed sale of its antibiotics division to American Cyanamid Dec. 1, for a cash payment of $12 million, an amount which is approximately $6 million in excess of the book value of the assets sold (C&EN, Nov. 9, page 4 6 5 1 ) .

Cyanamid most of the inventories of its antibiotics division for a price to be paid in cash, which, it is estimated, will approximate 8 5 % of their book value and will result in a net realization in excess of $1.5 million. Proceeds from sale of Hey den's antibiotics division and antibiotic inventories will increase its net working capital to approximately $21 million and its cash or equivalent assets not required to pay accrued taxes to approximately $18 million. Assets sold to American Cyanamid included Heyden's Princeton plant and nil intangible assets of the antibiotics division including all patents, p a t e n t applications, and inventions relating to antibiotics. Assets did not include Heyden's stock interest and royalty arrangement i n the French antibiotics company, Society Industrielle Pour la Fabrication des Antibiotiques; H e y d e n now is engaged in disposing of these assets.
