Abstract
Aspects of the invention provide a process for upgrading a hydrocarbon feed. The process includes providing a hydrocarbon feed and a utility fluid. Then selectively extracting from the feed at least a portion of particulates to produce a raffinate and an extract. Third hydroprocessing at least a portion of the raffinate.
Claims20
An upgrading system for upgrading a hydrocarbon feed, comprising:
- (a) a fluid-feed supply for supplying a fluid-feed mixture comprising a hydrocarbon feed and a utility fluid, the fluid-feed mixture having first and second particulates, the first particulates having a size ≥25 μm, and the second particulates having a size in the range of 1.0 to 20.0 μm;
- (b) a separation system adapted for selectively extracting from the fluid-feed mixture at least a portion of the first particulates to produce a raffinate comprising ≥50 wt. % of the second particulates and an extract comprising ≥50 wt. % of the first particulates;
- (c) a hydroprocessor for hydroprocessing at least a portion of the raffinate wherein the raffinate comprises ≥50 wt. % of the second particulates present in the fluid-feed mixture when supplied to the hydroprocessor;
- and
- (d) a conduit for transferring the raffinate comprising ≥50 wt. % of the second particulates from the separation system to the hydroprocessor.

An upgrading system for upgrading a hydrocarbon feed, comprising:
- a conduit configured to direct a fluid-feed mixture into a separation system, the fluid-feed mixture comprising a hydrocarbon feed, a utility fluid, a plurality of first particulates having a size ≥25 μm, and a plurality of second particulates having a size of 1.0 to 20.0 μm, wherein the separation system is configured to selectively separate the first particulates from the fluid-feed mixture by sedimentation, filtration, extraction, centrifugation, or a combination thereof to produce a raffinate comprising ≥50 wt. % of the second particulates present in the fluid-feed mixture and an extract comprising ≥50 wt. % of the first particulates present in the fluid-feed mixture;
- and
- a conduit configured to direct the raffinate comprising ≥50 wt. % of the second particles present in the fluid-feed mixture into a hydroprocessor, wherein the hydroprocessor is configured to hydroprocess the raffinate comprising ≥50 wt. % of the second particles present in the fluid-feed mixture to produce a hydroprocessed effluent.
