Abstract

Viene descritto un processo per la rimozione spinta di gas acidi quali H2S e/o CO9 da miscele gassose che li contengono comprendente essenzialmente un assorbimento mediante un solvente ed una rigenerazione del solvente esausto, in cui il solvente è costituito da una miscela acquosa di dimetiletanolammina (DMEA) avente una concentrazione in peso di DMEA compresa fra il 30 e il 70% e da un promotore, prodotto dalla reazione fra la formaldeide ed una o più polialchilenpoliammine, in quantità non superiore al 30% in peso rispetto alla DMEA.
