Summary: | Utilization of at least three strippers is proposed for a slurry hydrocracking unit to reduce heater duty for a product fractionation column. A stripping column for stripping a hydrocracked stream from a wash oil stripper is proposed in addition to a cold stripper for a cold hydrocracked stream and a warm stripper for a warm hydrocracked stream. The arrangement enables omission of heating a hot hydrocracked stream from a hot separator in a fired heater before product fractionation. |
