Abstract
A vacuum separator is used to separate a pitch stream from a slurry hydrocracking reactor upstream of the product fractionation column. The process and apparatus removes pitch from the product streams to enable easier separation of light VGO from heavy VGO in a fractionation column.
Claims20
A process for slurry hydrocracking comprising:
- slurry hydrocracking a hydrocarbon feed in a slurry hydrocracking reactor to provide a hydrocracked effluent stream;
- separating a hot hydrocracked stream, taken from said hydrocracked effluent stream, under vacuum pressure to provide a vapor vacuum stream and a pitch stream;
- recycling said pitch stream to slurry hydrocracking;
- and
- fractionating said vapor vacuum stream.

An apparatus for slurry hydrocracking comprising:
- a slurry hydrocracking reactor;
- a vacuum separator in downstream communication with said slurry hydrocracking reactor;
- and
- a fractionation column in downstream communication with said vacuum separator.
