Abstract

1301874 Steam recovery in hydrocarbon conversions UNIVERSAL OIL PRODUCTS CO 1 June 1970 26277/70 Heading C5E In an endothermic process for the catalytic conversion of hydrocarbons in the presence of steam, particularly the dehydrogenation of ethylbenzene to styrene, the total reaction effluent is cooled; separated into a hydrocarbon stream, from which the product is recovered, and an aqueous stream contaminated with hydrocarbons; the aqueous stream is passed to a treating zone to remove some of the contaminants and then to a filtration zone to remove the remaining contaminants and give a purified condensate; steam is produced from this condensate and recycled to the reaction zone. The treating zone may be a fractionating zone.
