Claim:
1. A hydroprocessing process comprising: hydroprocessing a hydrocarbon feed in a hydroprocessing reactor to provide hydroprocessing effluent stream; separating the hydroprocessing effluent stream in a hot separator to provide a hot vaporous stream and a hot liquid stream comprising a portion of a relatively hot hydroprocessed hydroprocessing effluent stream; separating the hot vaporous stream in a cold separator to provide a cold vaporous stream and a cold liquid stream comprising a portion of a relatively cold hydroprocessing effluent stream; stripping said relatively cold hydroprocessing effluent stream with stripping media in a cold stripper in a stripping vessel to provide a cold stripped stream; stripping said relatively hot hydroprocessing effluent stream with stripping media in a hot stripper in said stripping vessel to provide a hot stripped stream; and preventing material from said hot stripper from entering said cold stripper by means of a barrier.
