Abstract

1390382 Cracking EXXON RESEARCH & ENG CO 23 Feb 1972 [1 March 1971] 8245/72 Heading C5E A hydrocarbon feedstock, e.g. naphtha, is steam-cracked to unsaturated products, and the cracked material is cooled to below 850‹ F. in a heat exchanger, and further cooled to a temperature in the range 500‹ to 650‹ F. by quenching with a steam-cracked gas oil boiling between 350‹ and 750‹ F. and a steam-cracked distillation residue boiling between 550‹ and 800‹ F. A liquid phase is maintained on the wall of the transfer line to prevent fouling and plugging and so to increase useful heat recovery. The quenched material may be fractionated, and appropriate fractions, after cooling, may be used in part as the quenching oils.
