Abstract
Methods of recovering droplets of ionic liquid catalyst from a process stream are described. The volume fraction of ionic liquid in the hydrocarbon is increased to cause the ionic liquid droplets to coalesce. One method incorporates various combinations of gravity separation zone(s) and fractionation zones. Another method involves using a combination of a flash vessel and a fractionation zone, as well as an optional gravity separation zone.
