Abstract
A process for the production of a HS-enriched Hgas stream without the need for HS 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 HS content of the resulting gas stream can be readily controlled by adjusting the stripping pressure and/or hydrogen rate. The HS-enriched Hgas stream is suitable for the sulfidation of catalytically active metals.
