Abstract (en)
[origin: WO2007009943A1] The invention provides a process for producing a gas stream depleted of H<SUB>2</SUB>S and of RSH from a feed gas stream comprising H<SUB>2</SUB>S and RSH, the process comprising the steps of : (a) contacting the feed gas stream with absorbing liquid in a H<SUB>2</SUB>S removal zone to obtain a gas stream depleted of H<SUB>2</SUB>S; (b) contacting the gas stream obtained in step (a) with aqueous scrubbing solution comprising CUSO<SUB>4</SUB> in a RSH removal zone to obtain a mixture comprising Cu-alkylsulphide products and the gas stream depleted of H<SUB>2</SUB>S and depleted of RSH.
