Process for recovering hydroprocessed hydrocarbons with two strippers in series

摘要

A process is disclosed for recovering hydroprocessing effluent from a hydroprocessing unit utilizing a hot stripper and a cold stripper. A net overhead stream from the hot stripper is forwarded to the cold stripper for further stripping. The invention is particularly suitable for hydrotreating residue feed streams. The hot stripped stream may be subjected to fluid catalytic cracking. The apparatus and process eliminates the need for a fired heater in the product recovery unit.

主权项

1. A hydroprocessing process comprising:
hydroprocessing a hydrocarbon feed in a hydroprocessing reactor to provide a hydroprocessing effluent stream; stripping a relatively hot hydroprocessing effluent stream which is a portion of said hydroprocessing effluent stream in a hot stripper to provide a hot stripped stream; feeding said hot stripped stream to a fluid catalytic cracking unit; and stripping a relatively cold hydroprocessing effluent stream which is a portion of said hydroprocessing effluent stream and a stream from said hot stripper in a cold stripper to provide a cold stripped stream.
