  • Hydrogen sulfide stream for catalyst sulfidation from refinery rich amines
    Patent number: 8883036
    Abstract: A process for the production of a H2S-enriched H2 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 H2 gas stream is suitable for the sulfidation of catalytically active metals.
