Abstract
A process for hydrotreating a hydrocarbon residue stream is provided. The process comprises hydrotreating the hydrocarbon residue stream over a demetallation catalyst to demetallize the hydrocarbon residue stream to provide a demetallized hydrocarbon residue stream reduced in metals and sulfur concentration. The demetallized hydrocarbon residue stream is separated in a hot separator to provide an overhead vapor stream comprising hydrogen and a bottoms liquid stream. The bottoms liquid stream is split into a first liquid stream and a second liquid stream comprising low sulfur fuel oil. The second liquid stream is recovered as a low sulfur fuel oil product stream. The first liquid stream is hydrotreated over a desulfurization catalyst in the presence of at least a portion of the overhead vapor stream to provide a desulfurized hydrocarbon residue stream. The present process provides low sulfur fuel oil product stream comprising from about 0.3 wt % to about 1.5 wt % sulfur.
