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 12):
An apparatus for recovering hydrocracked product comprising:\n a hydrocracking reactor; a separator in communication with the hydrocracking reactor; a hot stripping column in communication with a bottoms line extending from a bottom of the separator; a cold stripping column in communication with an overhead line extending from an overhead of the separator; and a hot bottoms line extending from a bottom of the hot stripping column and a cold bottoms line extending from a bottom of the cold stripping column; a heat exchanger having one side in communication with said hot bottoms line and another side in communication with said cold bottoms line.
