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: 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.
