ABSTRACT:
Normal butane withdrawn from the main fractionator in an acid alkylation process is recycled to the main fractionator as required to insure that the actual alkylate to normal butane ratio in the alkylate product withdrawn from the main fractionator does not go below a desired ratio. Maintenance of the actual ratio at or above the desired ratio substantially minimizes the concentration of isobutane in the alkylate product stream.
