Abstract
In an alkylation process in which an acid regenerator is utilized to separate an acid catalyst from acid soluble oil contained in a spent acid catalyst stream, the heat input to the acid regenerator is manipulated based on the feed flow rate of the spent acid catalyst stream so as to maintain a substantially constant heat input per pound of feed flowing to the acid regenerator and the liquid level in the acid regenerator is manipulated so as to maintain the acid catalyst and acid soluble oil interface in the acid regenerator at a desired level. Such manipulation of the heat input to and the liquid level in the acid regenerator results in a substantially optimum separation of acid catalyst from acid soluble oil.
