First Claim
Patent Images
1. A hydroprocessing process comprising:
- hydroprocessing a hydrocarbon feed stream in a hydroprocessing reactor to provide hydroprocessing effluent stream;
stripping a hydroprocessing effluent stream in a stripper column;
providing a cold stripped stream and a hot stripped stream;
fractionating the hot stripped stream in vacuum product fractionation column.

Abstract
A hot stripped hydroprocessed stream from a stripper column may be sent directly to a vacuum fractionation column instead of being first processed in an atmospheric fractionation column. If a separate warm stripper column is used, both the warm stripped stream and a hot stripped stream may be fractionated in the same fractionation column, particularly a vacuum fractionation column.
