Abstract

According to the invention, acid gases are absorbed from a gas mixture by contacting this gas mixture with a liquid in which is dissolved so high a concentration of an amino acid or a salt thereof that a precipitate is formed. The contact takes place in a column of the packing-free type or a column suitable for processing slurries.
