Abstract
Abstract Selective absorption of H2S from gas mixture containing H2S and CO2 into aqueous solutions of 2–(tert–butylamino) ethanol (TBE) and 2–amino–2–methyl–1–propanol (AMP) at different temperature was investigated at high pressure by using a static gas absorption method. The influence of temperature and contact time on the absorption of H2S was investigated. The rates of absorption of H2S and the selectivity factor decreased with the increase of absorption temperature. With increasing contact time for both alkanolamine solutions, the selectivity factor increased at first and then decreased.
