专利汇可以提供Separation of carbon dioxide and hydrogen sulfide from gas mixtures专利检索,专利查询,专利分析的服务。并且A method permitting the reduction of absorber cross-sectional area when removing CO2 and/or H2S from gas mixtures containing a high partial pressure of such acid gases by means of regenerable aqueous alkaline scrubbing solutions. The gas mixture is contacted with the scrubbing solution in an absorption stage maintained under substantial superatmospheric pressure and containing at least two absorption zones. Each absorption zone is separately supplied with approximately equal, separate streams of regenerated scrubbing solution, and separate streams of spent scrubbing solution are withdrawn from the bottom of each absorption zone. The gas mixture to be purified passes successively through the separate absorption zones with approximately equal quantities of acid gas being absorbed in each zone. The scrubbing solution is regenerated at reduced pressure and recycled to the absorption zone.,下面是Separation of carbon dioxide and hydrogen sulfide from gas mixtures专利的具体信息内容。
