Abstract
A process for recovering hydrocarbons from a slurry hydrocracking reactor. The hydrocarbons are recovered by taking a drag stream of the slurry in the reactor. After separating lighter hydrocarbons in a separation zone, the heavier hydrocarbons can be processed in a deashing zone, with a vacuum column bottoms from a separation of the effluent stream recovered from the reactor. The deashing zone can recover the heavier hydrocarbons in a deashed pitch. Additionally, a VGO rich stream from the deashing zone may be recycled back to the reactor.
