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%.
