Patent

CA 2243626

The invention relates to a process of hydrotreatment of petroleum (1) containing sulphur and nitrogen, catalytic cracking of the ammonia produced by the hydrotreatment process in an oven (F), cooling (E2) of the cracking effluent, extraction of the hydrogen sulfide in an amine washing unit (20) and separation (SM) of the hydrogen from the resulting effluent. The recovered hydrogen is recycled in a hydrotreatment unit by a conduit (17).

On décrit dans un procédé d'hydrotraitement (HDT) d'une charge (1) pétrolière contenant du soufre et de l'azote, le craquage catalytique de l'ammoniac, produit par le procédé d'hydrotraitement, dans un four (F), le refroidissement (E2) de l'effluent de craquage, l'extraction de l'hydrogène sulfuré dans une unité (20) de lavage aux amines et la séparation (SM) de l'hydrogène de l'effluent en résultant. L'hydrogène récupéré est recyclé dans l'unité d'hydrotraitement (HDT) par un conduit (17).
