摘要： A method is described for separating CO2 and/or H2S from a mixed gas stream by contacting the gas stream with a non-aqueous, liquid absorbent medium of a primary and/or secondary aliphatic amine, preferably in a non-aqueous, polar, aprotic solvent under conditions sufficient for sorption of at least some of the CO2. The solution containing the absorbed CO2 can then be treated to desorb the acid gas. The method is usually operated as a continuous cyclic sorption-desorption process, with the sorption being carried out in a sorption zone where a circulating stream of the liquid absorbent contacts the gas stream to form a CO2-rich sorbed solution, which is then cycled to a regeneration zone for desorption of the CO2 (advantageously at 0.5:1 (approaching 1:1) may be achieved.

摘要： A CO2 amine scrubbing process uses an absorbent mixture combination of an amine CO2 sorbent in combination with a non-nucleophilic, relatively stronger, typically nitrogenous, base. The weaker base(s) are nucleophilic and have the ability to react directly with the CO2 in the gas stream while the relatively stronger bases act as non-nucleophilic promoters for the reaction between the CO2 and the weaker base. The sorption and desorption temperatures can be varied by selection of the amine/base combination, permitting effective sorption temperatures of 70 to 90° C., favorable to scrubbing flue gas.

摘要： A CO2 amine scrubbing process uses an absorbent mixture consisting of an alkanolamine CO2 sorbent in combination with a non-nucleophilic base. The alkanolamine has oxygen and nitrogen sites capable of nucleophilic attack at the CO2 carbon atom. The nucleophilic addition is promoted in the presence of the non-nucleophilic, relatively stronger base, acting as a proton acceptor. The non-nucleophilic base promoter, which may also act as a solvent for the alkanolamine, can promote reaction with the CO2 at each of the reactive hydroxyl and nucleophilic amine group(s) of the alkanolamines. In the case of primary amino alkanolamines the CO2 may be taken up by a double carboxylation reaction in which two moles of CO2 are taken up by the reacting primary amine groups.

摘要： A process for increasing the selectivity of an alkanolamine absorption process for selectively removing hydrogen sulfide (H2S) from a gas mixture which also contains carbon dioxide (CO2) and possibly other acidic gases such as COS, HCN, CS2 and sulfur derivatives of C1 to C4 hydrocarbons, comprises contacting the gas mixture with a liquid absorbent which is a severely sterically hindered capped alkanolamine. The improvement in selectivity is achieved at the high(er) pressures, typically least about 10 bara at conditions nearing the H2S/CO2 equilibrium at which CO2 begins to displace absorbed hydrosulfide species from the absorbent solution.
