摘要： The invention relates to gas separation, in particular to separation of CO2 from CO2-rich liquids, particularly from CO2 absorption liquids used in the removal of CO2 from off-gases or product flows, such as natural gas or synthesis gas. According to the invention, CO2 is separated from a CO2-rich liquid by a method comprising a step wherein, under elevated pressure, said liquid is contacted with a membrane based on polyacetylene substituted with trimethylsilyl groups such that the pressure across the membrane is at least 1 bar and that at least a part of the CO2 is transported from the liquid through the membrane.

摘要： The invention is directed to a method for separating gases in a mixed gas feed stream, and to an apparatus for carrying out said method. The method of the invention comprises: i) contacting the mixed gas feed stream with an absorption liquid in an absorption column at a pressure of 1 bar or more, said absorption liquid being selective for absorption of one or more gases in the mixed gas feed stream so that part of the gas in the mixed gas feed stream is absorbed by the absorption liquid resulting in a rich absorption liquid; ii) regenerating at least part of the absorption liquid by contacting the rich absorption liquid with a desorption membrane, wherein the pressure at the retentate side of the desorption membrane is at least 1 bar higher than the pressure at the permeate side of the desorption membrane so that at least part of the absorbed gas desorbs from the rich absorption liquid and permeates through the desorption membrane thereby forming a lean absorption liquid; and iii) recycling at least part of the lean absorption liquid to step i) for contacting with the mixed gas feed stream.
