Process for recovering hydroprocessed hydrocarbons with two strippers and common overhead recovery

摘要

A process is disclosed for recovering hydroprocessing effluent from a hydroprocessing unit utilizing a hot stripper and a cold stripper. The cold stripper and the hot stripper utilize a common overhead recovery apparatus.

主权项

1. A hydroprocessing process comprising:
hydroprocessing a hydrocarbon feed in a hydroprocessing reactor to provide hydroprocessing effluent stream; stripping a relatively cold hydroprocessing effluent stream with a stripping media in a cold stripper to provide a cold stripped stream and a cold vapor stream; feeding the cold stripped stream to a product fractionation column; stripping a relatively hot hydroprocessing effluent stream with stripping media in a hot stripper to provide a hot stripped stream and a hot vapor stream; feeding the hot stripped stream to said product fractionation column; preventing material from the hot stripper from mixing with material from the cold stripper by means of a barrier; and condensing said cold vapor stream and said hot vapor stream in a condenser to provide a condensed overhead stream.
