ABSTRACT:
An olefin and isoparaffin are contacted in the presence of an acid alkylation catalyst to form an alkylate-containing alkylation effluent. The effluent is separated with the hydrocarbon phase passing to a prefractionation zone. A side stream from the prefractionation zone is passed in indirect heat exchange relationship with an interheater of an isostripper thereby providing a majority of the heat necessary to reboil the isostripper.
