Abstract
Disclosed is a method of alkylating in which a hydrocarbon and acid emulsion is circulated in a reaction loop between a reactor and a cooler. A small sidestream of the reaction emulsion is constantly removed to a liquid-liquid separator where the hydrocarbon and acid phases are separated. The recovered acid is then recycled back to the reaction loop. The amount of recovered acid recycled is controlled by monitoring the density of the reaction emulsion.
