Abstract of the Disclosure In an alkylation process wherein the amount of hydrogen fluoride (HF) acid catalyst required to maintain a desired HF acid/hydrocarbon ratio in a plurality of alkylation reactors is contained in the lower portion of a common settler vessel, the improvement comprises: dividing the lower portion of the common settler vessel into a plurality of chambers for containing the desired amount of HF acid catalyst, such that a leak affecting the catalyst handling system for one of the plurality of reactors would only spill the amount of liquid HF acid contained in one of the chambers, and would not affect the liquid HF acid level in a non-leaking chamber.
