Title (EN) PROCESS FOR PRODUCING A GAS STREAM DEPLETED OF HYDROGEN SULPHIDE AND OF MERCAPTANS
(FR) PROCEDE DE PRODUCTION D'UN FLUX GAZEUX APPAUVRI EN SULFURE D'HYDROGENE ET EN THIOLS
Abstract:
(EN) The invention provides a process for producing a gas stream depleted of H2S and of RSH from a feed gas stream comprising H2S and RSH, the process comprising the steps of : (a) contacting the feed gas stream with absorbing liquid in a H2S removal zone to obtain a gas stream depleted of H2S; (b) contacting the gas stream obtained in step (a) with aqueous scrubbing solution comprising CUSO4 in a RSH removal zone to obtain a mixture comprising Cu-alkylsulphide products and the gas stream depleted of H2S and depleted of RSH.
(FR) La présente invention concerne un procédé de production d'un flux gazeux appauvri en H2S et en RSH à partir d'un flux gazeux d'alimentation comprenant H2S et RSH, lequel procédé consiste: (a) à mettre le flux gazeux d'alimentation en contact avec un liquide absorbant dans une zone d'extraction de H2S pour obtenir un flux gazeux appauvri en H2S; (b) à mettre le flux gazeux obtenu à l'étape (a) en contact avec une solution de lavage aqueuse comprenant CUSO4 dans une zone d'extraction de RSH pour obtenir un mélange comprenant des produits de Cu-alkylsulfure et le flux gazeux appauvri en H2S et appauvri en RSH.
