HYDROCRACKING PROCESS AND APPARATUS

A process and apparatus removes HPNA's from a fractionated bottoms stream from a reboiled product fractionation column that obtains heat from a reboiler. HPNA's are removed from the fractionated bottoms stream by stripping it with an inert gas. The HPNA lean stream may be fed back to the r...

Summary:A process and apparatus removes HPNA's from a fractionated bottoms stream from a reboiled product fractionation column that obtains heat from a reboiler. HPNA's are removed from the fractionated bottoms stream by stripping it with an inert gas. The HPNA lean stream may be fed back to the reboiled product fractionation column at the same elevation as the feed stream to the column.
