Abstract
Cryogenic process for the removal of acidic gases from natural gases or from synthesis gases essentially comprising the absorption in one or more towers in order to reduce the content of acidic gases, a cooling carried out, in the case of one single absorber tower, upstream the same tower, or, in case of two absorber towers, between the same towers, a regeneration of the solvent or of the solvents used in the absorption, the solvent or the solvents used being selected among low molecular weight esters, alcohols and ethers, characterized in that with the solvent or solvents the gas outcoming from one or more of the absorber towers is mixed once or more times, the mixtures thus formed being then cooled, the solvent being thus separated from the same gas.
