Abstract
In an acid alkylation process wherein a fresh isobutane stream is combined with an olefin stream to form a combined isobutane olefin feed stream, a control system maintains a desired ratio of isobutane to olefin in the combined feed stream by manipulating the flow rate of the fresh isobutane stream. In addition, the controller automatically compensates for the effect of changes in the fresh isobutane feed stream by making equal changes in the flow rate of reactor effluent. Thus, the liquid level in the alkylation reactor is unaffected by changes made in the fresh isobutane stream to maintain the desired isobutane to olefin ratio.
