Utilization of isoparaffin is maximized in an alkylation of isoparaffin with olefin by variously detecting and/or measuring change in amount of hydrocarbon effluent, the alkylation zone and supplying a sufficient amount of olefin to said alkylation zone to keep the amount of hydrocarbon effluent said alkylation zone substantially constant, in one embodiment sensing the level of hydrocarbon in a settling zone in which alkylation zone effluent is settled, said level being representative of the amount of hydrocarbon being formed, and increasing the amount of olefin when effluent the alkylation zone is increasing, and vice versa.
