An integrated coalescing system for separating ionic liquid from a liquid hydrocarbon is provided, comprising:a. a bulk settler,that separates an emulsion comprising the dispersed ionic liquid with a wide range of droplet sizes into a clean ionic liquid phase and a separated liquid hydrocarbon phase comprising retained droplets;b. a pre-coalescer that receives the separated liquid hydrocarbon phase, separates out solid particles from the separated liquid hydrocarbon phase, and begins to form coalesced droplets of the retained droplets; andc. a coalescer that receives an effluent from the pre-coalescer, wherein the at least one coalescer comprises multiple layers of media having a fine pore size, and produces a clean hydrocarbon stream that is free of the dispersed ionic liquid and additional amounts of the clean ionic liquid phase. Also, a process is provided for separating an ionic liquid from a liquid hydrocarbon, using the integrated coalescing system.
