    摘要: 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.

    摘要: Acid gas is removed from a high pressure feed gas that contains significant quantities of CO2 and H2S. In especially preferred configurations and methods, feed gas is contacted in an absorber with a lean and an ultra-lean solvent that are formed by flashing rich solvent and stripping a portion of the lean solvent, respectively. Most preferably, the flash vapors and the stripping overhead vapors are recycled to the feed gas/absorber, and the treated feed gas has a CO2 concentration of less than 2 mol % and a H2S concentration of less than 10 ppmv, and more typically less than 4 ppmv.

    摘要: Contemplated NGL plants include a feed gas bypass circuit through which a portion of the feed gas is provided downstream to a vapor portion of the feed gas to thereby increase turbo expander inlet temperature and demethanizer temperature. Contemplated configurations are especially advantageous for feed gases with relatively high carbon dioxide content as they entirely avoid carbon dioxide freezing in the demethanizer, provide additional power production by the turboexpander, and recover C2+ components to levels of at least 80% while achieving a low carbon dioxide content in the NGL product.
