摘要： A process for the recovery of carbon dioxide, comprising: (a) an absorption step of bringing a carbon dioxide-containing gaseous feed stream into gas- liquid contact with an absorbing fluid, whereby at least a portion of the carbon dioxide present in the gaseous stream is absorbed into the absorbing fluid to produce (i) a refined gaseous stream having a reduced carbon dioxide content and (ii) an carbon dioxide-rich absorbing fluid, (b) a regeneration step of treating the carbon dioxide-rich absorbing fluid at a pressure of greater than 3 bar (absolute pressure) so as to liberate carbon dioxide and regenerate a carbon dioxide-lean absorbing fluid which is recycled for use in the absorption step, wherein the absorbing fluid is an aqueous amine solution containing a tertiary aliphatic alkanol amine and an effective amount of a carbon dioxide absorption promoter, the tertiary aliphatic alkanol amine showing little decomposition under specified conditions of temperature and pressure under co-existence with carbon dioxide. The tertiary aliphatic alkanol amine does not contain, in its molecular structure, a nitrogen atom that is substituted by more than one 2-hydroxyethyl moieties, or a nitrogen atom that is substituted by both a 2-hydroxyethyl moiety and a methyl moiety. Preferred tertiary aliphatic alkanol amines are selected from the group consisting of N-ethyl-diethanolamine, 2-(dimethylamino)-ethanol, 2- (diethylamino)-ethanol, 3-(dimethylamino)-1-propanol, 3-(diethylamino)-1- propanol, 1-(dimethylamino)-2-propanol, and 2-(diisopropylamino)-ethanol.

摘要： A process for removing carbon dioxide from a fluid comprising the steps of: treating the fluid by contacting it with a liquid absorbent in a first absorption zone and thereafter in a second absorption zone depressurizing the absorbent (3 to 1 bar (absolute)) to release a first stream of CO2 and yield a partially regenerated absorbent; which is recycled in a first stream into the first absorption zone; heating (at 3.5 to 10 bar (absolute))a second stream of the partially regenerated absorbent to release a second stream of CO2 and yield a regenerated absorbent; which is recycled into the second absorption zone; condensing water vapour entrained in the second stream of CO2 by cooling the second stream of CO2 and transferring at least part of the heat recovered to the partially regenerated absorbent by indirect heat exchange; and introducing the second stream of CO2 into a CO2 pressurizing unit.
