Selective Recovery of Components of Coke-Oven Gas in the Benzene Department of a Coke Plant

Abstract

Benzene hydrocarbons are captured in a multicomponent system consisting of coke-oven gas and absorbing oil. On that basis, it is of interest to consider the possibility of selective impurity capture. The benzene department of the coke plant may be used for more complete removal of organosulfur compounds from coke-oven gas. The possibility of more selective recovery of benzene hydrocarbons in the presence of sulfur-bearing and unsaturated components is considered. That would permit optimization of the reagent consumption in sulfuric-acid washing during the rectification of raw benzene.
