Abstract:
A process and apparatus for hydrocracking a hydrocarbon stream and with heat integration between two stripping columns. Both stripping columns use a reboiler for heat input to avoid steam recovery and dew point issues in the overhead. A hot stripped stream can provide heat to the cold stripping column by heat exchange. Additionally, as few as two heaters that rely on external utilities may be required for reboiling fractionator column bottoms.

Claim (Index 15):
A process for recovering hydrocracked product comprising:\n hydrocracking a feed stream in a hydrocracking reactor with a hydrogen stream over hydrocracking catalyst to provide a hydrocracked stream; separating said hydrocracked stream into a hot liquid hydrocracked stream and a cold liquid hydrocracked stream; stripping said hot liquid hydrocracked stream in a hot stripping column to provide a hot stripped stream; boiling up a hot reboil stream taken from said hot stripped stream and returning it to the hot stripping column; stripping said cold liquid hydrocracked stream in a cold stripping column to provide a cold stripped stream; boiling up a cold reboil stream taken from said cold stripped stream and returning it to the cold stripping column; and taking a hot stripped stream from a bottom of said hot stripping column and heating said cold reboil stream by heat exchange with said hot stripped stream.
