    Abstract: We provide a segmented reactor for regenerating a spent acidic ionic liquid via hydrogenation and hydrocracking, comprising: no solid hydrogenation catalyst; a gas inlet for feeding a gas feed comprising a hydrogen; a liquid inlet for feeding a spent acidic ionic liquid; partitions along an axis of the reactor that create segments, wherein each segment functions as a bubble column reactor; and an outlet from which a regenerated acidic ionic liquid flow out of the segmented reactor. We also provide a process for regenerating a spent acidic ionic liquid, comprising contacting the spent acidic ionic liquid with hydrogen and without an addition of a solid hydrogenation catalyst in the segmented reactor.

    Abstract: A phase separation assembly includes a stand pipe configured to be located at a bottom of a distillation column, the stand pipe for directing a liquid phase of a hydrocarbon fluid through a bottom outlet to a heating assembly; a return conduit configured to direct heated hydrocarbon fluid from the heating assembly into the distillation column; a ring baffle configured to be located within the distillation column above the return conduit; and a horizontal plate configured to be disposed above the stand pipe. The ring baffle directs the heated hydrocarbon fluid around the inner circumferential wall of the distillation column so that vapor and liquid phases can separate. Weir features on the ring baffle can facilitate separation of vapor and liquid flows of the hydrocarbon.

    Abstract: A process for injecting an immiscible liquid stream comprising a co-catalyst for a hydrocarbon conversion into a larger liquid stream that is an ionic liquid catalyst for the hydrocarbon conversion, comprising: a. feeding the immiscible liquid stream towards one or more injection quills in an additive delivery system comprising a transfer drum; b. transferring the immiscible liquid stream from the additive delivery system to the one or more injection quills in a solvent flushing system, fluidly connected downstream from the additive delivery system, wherein the solvent flushing system injects a solvent into one or more additive addition lines in the solvent flushing system; and c. continuously injecting the immiscible liquid stream into the larger liquid stream in an additive injection and mixing system comprising the one or more injection quills.

    Abstract: 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; and c. 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.
