Abstract
In an HF alkylation process, ASO is separated from HF acid catalyst in a fractionation zone by heating the fractionation zone with a condensible stream comprising liquid and vaporous components. In the process of condensation, latent heat is evolved which is used to effectuate the separation of ASO and HF acid catalyst and dilution of the separated ASO is achieved with the use of the produced condensate.
