Aromatic Hydrocarbons. Sulfolane is used principally as a solvent for extraction of benzene, toluene, and xylene from mixtures containing aHphatic hydrocarbons (33—37). The sulfolane process was introduced in 1959 by SheU Development Company, and that process is Hcensed by Universal OH Products. A sulfolane extraction process is also Hcensed by the Atlantic Richfield Company. In 1994, worldwide consumption was estimated at ca 6974 t/yr of sulfolane for 137 sulfolane extraction units (see Bix processes Extraction, liquid-liquid Xylenes and ethylbenzene).

A company may get capital by selling a subsidiary or a portion of its business. In 1969 Monsanto decided that it would quit the low-density polyethylene business. It sold its plant at Texas City, Tex., plus its research findings and technology concerning low-density polyethylene to Northern Petrochemical.14 In the same year Atlantic Richfield paid 1800,000 for a 30% interest in a mining lease on about 8,560 acres of oilshale reserves in eastern Utah.15 W. R. Grace Co. sold its 53% interest in the Miller Brewing Company to Philip Morris for 130,000,000 and made an after-tax profit of 54,000,000.16 In 1969 it also sold its steamship business. 

Atlantic Richfield Company has reported strains of Pseudomonas sp. CB1 (ATCC 39381) [108] and Acinetobacter species CB2 [109] (ATCC 53515) to be effective for the removal of sulfur from organic molecules found in petroleum, coal, etc. In fact, the aerobic and heterotrophic soil microorganisms Pseudomonas CB1 and Acinetobacter CB2 were reported to convert thiophene sulfur into sulfate, using a bench-scale continuous bioreactor. The direct contact with Illinois 6 coal reduced the organic sulfur content in about 40% to 50%. As already mentioned, most of this work was carried out on coal. Further work was not pursued probably due to decrease in coal usage or due to the economics of the processes. 

Atlantic Richfield Company, Arco has developed several conventional technologies for sulfur removal from coal and ashes and for manufacturing oil-coal mixed fuels, prior to becoming involved in BDS. Their patent entitled, Biodesulfurization of carbonaceous materials [16] was developed for the coal application, but nevertheless was extrapolated for application to petroleum desulfurization as well. 

Magnaforming A catalytic reforming process developed by the Atlantic Richfield Corporation and Englehard Corporation. First announced in 1965, it was commercialized in 1967 and by 1988, 150 units were operating worldwide. Hydrocarbon Research has installed units in Argentina, Algeria, and the USSR. 

Octafining A process for isomerizing m-xylene to o- and p-xylene, developed by the Atlantic Richfield Company in 1960. The catalyst was originally platinum on an aluminum silicate base now a zeolite base is used. The reaction takes place in a hydrogen atmosphere. Hydrocarbon Research installed units in Argentina and the USSR. 

Pentafining A process for isomerizing pentane in a hydrogen atmosphere, using a platinum catalyst supported on silica-alumina. Developed by the Atlantic Richfield Company. 

Seacoke A process for making tar and coke by carbonizing mixtures of coal and petroleum residuum. The tar would be used in an oil refinery and the coke would be used for generating electricity. The process was sponsored by the U.S. Office of Coal Research 1964-1969 the work was carried out by EMC Corporation, Atlantic Richfield Company, and Blaw-Knox Company. Results from the pilot plant were encouraging but the project was abandoned because the benefits were judged insufficient to justify the complexity. 

Xylenes-plus A catalytic process for isomerizing toluene to a mixture of benzene and xylenes. A silica/alumina catalyst is used in a moving bed. It is unlike the related Tatoray process, in that no hydrogen is required. Developed by Sinclair Research in 1964 and then licensed by Atlantic Richfield.

Although most facilities that refine crude petroleum in the United States produce a fuel oil. no. 1 fraction (HSDB 1991), only producers that market fuel oil no. 1 as an end product are listed as commercial manufacturers. These manufacturers include Claiborne Gasoline Company (Claiborne and Union Parish, Louisiana), Continental Oil Company (Acadia Parish, Louisiana), Sun Production Company (Starr County, Texas), Exxon Corporation (Pledger County, Texas), Atlantic Richfield Company (New York, New York), and Shell Oil Company (Houston, Texas) (HSDB 1991). Since fuel oils nos. 1, 1-D, 2, 2-D, and 4, and fuel oil UNSP are not required to be reported under SARA Section 313, there are no data for these fuel oils in the 1990 Toxics Release Inventory (TRI90 1992).
