Abstract: A system and process for extending turndown in a gas-liquid separator is presented. The system includes a first mist extractor with a first operating range and a second mist extractor with a second operating range. The mist extractors are generally of the same type, with the second operating range being different than the first operating range. A gas stream containing entrained liquid droplets flows through the first mist extractor and then through the second mist extractor. Each mist extractor coalesces and captures the liquid droplets within its own operating range, expanding the overall operating range of the separator. Additional mist extractors may be added to cover any gap between the first and second operating ranges.

Abstract: CO2 is removed from high-pressure feed gas in configurations and methods according to the inventive subject matter by contacting feed gas with cooled semi-rich solvent to form a two-phase mixture that is flashed into the bottom section of an absorber. Rich solvent from the absorber is then reduced in pressure to generate refrigeration for the semi-rich solvent and lean solvent countercurrently contacts the partially treated feed gas in the absorber to produce the semi-rich solvent. Among other advantages, cooling of the feed gas and semi-rich solvent by the pressure reduced rich solvent heats the rich solvent to allow enhanced regeneration of the solvent, and external refrigeration and heating of the solvent can be entirely avoided.
