Abstract

Viene descritto un processo per rimuovere gas acidi quali idrogeno solforato e/o anidride carbonica da miscele gassose che li contengono comprendente essenzialmente un assorbimento mediante un solvente dei gas acidi ed una rigenerazione del solvente esausto utilizzato mediante strippaggio caratterizzato dal fatto che il solvente utilizzato è costituito da una miscela acquosa di dimetiletanolammina (DMEA) avente una concentrazione in peso di dimetiletanolammina compresa fra il 30 e il 70%.A process is described for removing acid gases such as hydrogen sulphide and / or carbon dioxide from gaseous mixtures containing them, essentially comprising an absorption of the acid gases by means of a solvent and a regeneration of the spent solvent used by stripping characterized in that the solvent used is constituted from an aqueous mixture of dimethylethanolamine (DMEA) having a concentration by weight of dimethylethanolamine between 30 and 70%.
