Patent ID: 11866657

Abstract:
A method of processing a hydrocarbon feedstock may comprise hydrotreating the hydrocarbon feedstock in a low-severity hydrotreater to produce a first effluent and hydrotreating the first effluent, or a portion thereof, in a high-severity hydrotreater to produce a low contaminant product. The low-severity hydrotreater may operate at a catalyst volume of less than 60% of a catalyst volume of the high-severity hydrotreater. The low-severity hydrotreater may operate at a hydrogen partial pressure of at least 5 bar lower than the hydrogen partial pressure in the high-severity hydrotreater. The low-severity hydrotreater may operate at a weighted average bed temperature (WABT) of at least 5° C. less than the WABT of the high-severity hydrotreater.
