PROCEDE DE DESACIDIFICATION D'UN GAZ PAR SOLUTION ABSORBANTE AVEC ELIMINATION DU COS PAR L'HYDROLYSE

摘要

The method deacidifies a gas including H2S and CO2. The gas is subjected to an absorption to collect the CO2 and the H2S in an absorber, then to conversion through hydrolysis of the COS to H2S and CO2 in a reactor, and to a second absorption to collect the H2S and the CO2 formed in the reactor. The absorbent solution is regenerated in regenerator. The regenerated absorbent solution is separated into two which are: a main stream supplying the absorber, and a remaining stream supplying the second absorption
