Abstract: Scrubbing out of CO2 and/or H2S from gases is effected at raised press., e.g. 5-100 atm., using aq. solns. of ethylene- or propylene-diamine derivs. substd. by >=1 alkyl, esp. Me, or hydroxyalkyl, esp. hydroxyethyl, gp. each, pref. N-dimethyl-N'-methylhydroxyethylethylene-diamine or N, N-dimethyl-N'-dihydroxyethylpropylene diamine, followed by regeneration of soln., e.g. by desorption and/or stripping or hot regeneration.
