Abstract: Separation processes and separation apparatus are described. The process includes introducing a stream of liquid containing dispersed droplets of another liquid into a separation apparatus comprising a vessel having at least one mesh screen covering substantially all of the cross-section of the vessel. The mesh screen is periodically slightly moved so that the wires of the mesh screen contact the dispersed droplets and some of the dispersed droplets coalesce on the wires. The coalesced droplets rise or fall from the wires through the stream of the second liquid. The coalesced droplets are collected in a portion of the vessel. A stream of the second liquid having a reduced level of dispersed droplets is recovered.

Abstract: A method for recovering entrained ionic liquid from an immiscible phase containing droplets of ionic liquid is described. The method includes contacting the immiscible phase containing the droplets of ionic liquid with a scrubbing ionic liquid phase in a scrubbing zone. The immiscible phase containing the droplets of ionic liquid has a first level of droplets of ionic liquid. At least a portion of the droplets of ionic liquid are transferred to the scrubbing ionic liquid phase to form a recovered ionic liquid phase comprising the scrubbing ionic liquid and the transferred portion of the droplets of ionic liquid and a second immiscible phase having a second level of droplets of ionic liquid lower than the first level. The second immiscible phase is separated from the recovered ionic liquid phase.

Abstract: A high capacity and high efficiency co-current and cross-flow vapor-liquid contacting apparatus and process is useful in distillation columns and other vapor-liquid contacting processes. The apparatus is characterized by an arrangement of offset contacting modules in horizontal stages. The modules define a co-current contacting volume and in an exemplary configuration the modules include a liquid distributor and a demister. Half modules comprise downcomers against the shell of the vessel for transporting liquid to the subjacent stage.

Abstract: Processes for controlling the rate and temperature of cooling fluid through a heat exchange zone in, for example, an alkylation reactor using an ionic liquid catalyst. A cooling fluid system may be used to provide the cooling fluid which includes a chiller and a reservoir. The cooling fluid may pass from the reservoir through the heat exchange zone. A bypass line may be used to pass a portion of the cooling fluid around the heat exchange zone. The amount of cooling fluid may be adjusted, with a valve, based upon the temperature of the cooled process fluid flowing out of the heat exchange zone. Some of the cooling fluid from the chiller may be circulated back to the chiller in a chiller loop.
