<p>A process for removing CO2 and/or H2S from a cracked gas by bringing the said gas, at from 20 to 60.degree.C and under atmospheric pressure or superatmospheric pressure, into contact, in an absorption zone, with an aqueous solution of the alkali metal salts of aminoacids as the scrubbing liquor, freeing the solution leaving the absorption zone from CO2 and/or H2S by heating in a desorption zone, if necessary after first letting down the pressure, and then recycling the so-regenerated scrubbing liquor to the absorption zone, wherein the scrubbing liquor used is an aqueous solution of an alkalimetal salt of a N-dialkyl-.alpha.-aminomonocarboxylic acid.</p> |
