ABSTRACT:
A process is provided for the alkylation of isoparaffins with olefins in the presence of an HF acid catalyst comprising separating a liquid hydrocarbon phase from the alkylation effluent, subjecting the hydrocarbon phase to HF stripping, separating the stripped hydrocarbon into a liquid and a vapor phase, fractionating the liquid phase into product streams, and pressurizing the vaporous stream prior to separation of C.sub.3 and lighter materials. The HF alkylation process utilizes indirect heat exchange of various streams and compression of HF-free vapors.
