DEVICE AND PROCESS FOR THE REDUCTION OF LIQUID SPILL, AND THE PROCESS OF AQUILACAO DE OLEFINAS USING THE DISCLOSURE DEVICE

摘要

In an alkylation process wherein the amount of hydrogen fluoride (HF) acid catalyst required to maintain a desired HT acid/hydrocarbon ratio in a plurality of alkylation reactors (10, 12) is contained in the lower portion of a common settler vessel (14), the improvement comprises: dividing the lower portion of the common settler vessel (14) 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 (10, 12) 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.
