Abstract
Desulphurization process for feedstocks in which the sulphur compounds contained therein are first separated into a concentrate stream which is then hydro-desulphurized, and the resulting hydrogen suphide removed using conventional sulphur removal techniques. The initial separation is preferably effected using membrane separation or temperature swing absorption processes.
