ABSTRACT:
Described in a process for hydrotreating (HDT) a petroleum feedstock (1) that contains sulfur and nitrogen are the catalytic cracking of the ammonia, produced by the hydrotreating process, in a catalytic cracking furnace (F), the cooling (E2) and separating of the cracking effluent to produce an H.sub.2 S containing gas phase, the extraction of the hydrogen sulfide from said gas phase and from the hydrotreating purge gas in an amine washing unit (20), and the separation (SM) of the hydrogen from the resultant effluent. The recovered hydrogen is recycled to hydrotreating unit (HDT) via a pipe (17).
