Patent ID: 8715595

Claim:
A hydroprocessing apparatus comprising: a hydroprocessing reactor; a hot stripper in communication with the hydroprocessing reactor for stripping a relatively hot hydroprocessing effluent stream with a hot stripping media provided by a line; a cold stripper in communication with the hydroprocessing reactor for stripping a relatively cold hydroprocessing effluent stream with a cold stripping media provided by another line, said cold stripper being in communication with said hot stripper; and a hot separator and a cold separator in communication with said hydroprocessing reactor for separating a hydroprocessing effluent stream from said hydroprocessing reactor into said cold hydroprocessing effluent stream and said hot hydroprocessing effluent stream; wherein the cold stripper is in downstream communication with the cold separator via a line comprising said cold hydroprocessing effluent stream from the bottom of the cold separator and said cold separator is in direct communication with an overhead of said hot separator.
