Abstract: An integrated system for monitoring a chemical concentration in an ionic liquid, comprising: a. an online FTIR instrument with an ATR window; b. a sample conditioning station that removes light hydrocarbons and produces a degassed ionic liquid that is analyzed by FTIR; and c. a solvent flushing system that flows solvent across the ATR window. Also, a process for monitoring the chemical concentration, comprising: a. degassing the ionic liquid in the sample conditioning station; b. passing the degassed ionic liquid over an ATR window; c. periodically redirecting a flow of the degassed ionic liquid via a bypass line or an on-off valve that isolates the ATR window from the process unit that elutes the ionic liquid; and d. flowing a solvent and a purging gas over the ATR window during the periodically redirecting step c); and e. resuming the passing of the degassed ionic liquid over the ATR window.

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 removing heavy polycyclic aromatic contaminants from a hydrocarbon stream using a quinolinium ionic liquid is described. The process includes contacting the hydrocarbon stream comprising the contaminant with a hydrocarbon-immiscible quinolinium ionic liquid to produce a mixture comprising the hydrocarbon and a hydrocarbon-immiscible quinolinium ionic liquid comprising at least a portion of the removed contaminant; and separating the mixture to produce a hydrocarbon effluent having a reduced level of the contaminant and a hydrocarbon-immiscible quinolinium ionic liquid effluent comprising the hydrocarbon-immiscible quinolinium ionic liquid comprising at least the portion of the removed contaminant.

Abstract: The present disclosure refers to systems and methods for efficiently converting a C1-C3 alkane such as natural gas to a liquid C2-C10 product and hydrogen. Generally, the process comprises flowing the C1-C3 alkane through a plurality of tubes within a vessel wherein the tubes house a catalyst for converting the C1-C3 alkane to the liquid C2-C10 product and hydrogen. The C1-C3 alkane is heated under suitable conditions to produce the liquid C2-C10 product and hydrogen. Advantageously, the C1-C3 alkane is heated by burning a fuel outside the tubes in fuel burning nozzles configured to transfer heat from the burning through the tubes.

Abstract: A process is provided for removing a heavy polynuclear aromatic (HPNA) compound from a hydrocarbon oil. The process includes contacting the hydrocarbon oil containing the HPNA compound with a lean hydrocarbon-immiscible liquid stream to produce a mixture comprising the hydrocarbon oil and a rich hydrocarbon-immiscible liquid containing the HPNA compound; and separating the mixture to produce a hydrocarbon oil effluent having a reduced level of the HPNA compound and a hydrocarbon-immiscible liquid effluent containing the HPNA compound. The hydrocarbon-immiscible liquid can be a halometallate ionic liquid, a liquid coordination complex, or a combination thereof.
