Solvent deasphalting (SDA) is used to prepare a heavy hydrocarbon feed for further upgrading. An overhead deasphalted oil (DAO) stream is prepared for catalytic upgrading and an asphaltene stream is prepared for slurry hydrocracking (SHC). SHC product can be further deasphalted and the DAO can be separated from solvent in an upstream extraction column.

Process and apparatus for integrating slurry hydrocracking and deasphalting

A process and apparatus for improving flow properties of crude may include processing a first crude stream, which may in turn include cracking the first crude stream with catalyst to form a cracked stream and spent catalyst, hydrotreating a portion of the cracked stream and then mixing the hydrotreated stream with an unprocessed second crude stream.

The residue (bottoms) from a vacuum or atmospheric column is upgraded in a revamped multireactor hydrotreating zone. The hydrotreating zone is modified such that the entire effluent of the next to last reactor is withdrawn, light gases and hydrocarbons are removed from the effluent in separators and the remaining liquid is passed into a fractionation column and/or a carbon rejection zone. Gas oils and distillates from the column and/or carbon rejection zone are then returned to the last reactor of the hydrotreating zone.
