ABSTRACT:
This invention relates to a crude oil desulfurization process which comprises hydrodesulfurizing a crude oil feed in a crude desulfurization unit. The desulfurized crude oil is then separated into a light gas oil fraction, a vacuum gas oil fraction and a vacuum residuum fraction. The vacuum gas oil is hydrocracked to form at least one low sulfur fuel product. The light gas oil fraction is hydrotreated. The vacuum gas oil may be hydrocracked in one or more stages. Hydrocracking in the second stage, if present, will convert of at least 20% of the first zone effluent, to create a low sulfur light gas oil fraction. The light gas oil fraction may then be hydrotreated.
