Zusammenfassung:A process for the production of a H2S -enriched H gas stream without the need for H2S compression is disclosed. A slip stream of rich amine from a hydroprocessing unit is reduced in pressure and stripped with a hydrogen containing gas. The H2S content of the resulting gas stream can be readily controlled by adjusting the stripping pressure and/or hydrogen rate. The H2S- enriched H gas stream is suitable for the sulfidation of catalytically active metals.
