Abstract

A processing facility is provided that includes a feedstock separation system configured to separate a feed stream into a lights stream and a heavies stream, a hydrogen production system configured to produce hydrogen and carbon dioxide from the lights stream, and a carbon dioxide conversion system configured to produce synthetic hydrocarbons from the carbon dioxide. The processing facility includes a hydroprocessing system configured to process the heavies stream.

First claim

What is claimed is:

1. A processing facility comprising:
a feedstock separation system configured to separate a feed stream into a lights stream and a heavies stream;
a hydrogen production system configured to produce hydrogen and carbon dioxide from the lights stream;
a carbon dioxide conversion system configured to produce synthetic hydrocarbons from the carbon dioxide; and
a hydroprocessing system configured to process the heavies stream.

2. The processing facility of claim 1 , wherein the feedstock separation system comprises a flash drum.

3. The processing facility of claim 1 , wherein the feedstock separation system comprises a cyclonic phase separation device.

4. The processing facility of claim 1 , wherein the hydrogen production system comprises a steam reforming reactor.

5. The processing facility of claim 1 , wherein the hydrogen production system comprises a gasification reactor.

6. The processing facility of claim 1 , wherein the hydrogen production system comprises a pressure swing adsorption system.

7. The processing facility of claim 1 , wherein the carbon dioxide conversion system comprises a Fischer-Tropsch reactor.

8. The processing facility of claim 1 , wherein the hydroprocessing system comprises a hydrodemetallization zone, a hydrodearomatization zone, a hydrodenitrogenation zone, a hydrodesulfurization zone, or a hydrocracking zone, or any combinations thereof.

9. The processing facility of claim 1 , comprising:
a hydroprocessor separation system configured to separate a hydroprocessor effluent from the hydroprocessing system into a separator tops stream and a separator bottoms stream;
a steam cracking system configured to process the separator tops stream; and
a heavy oil conversion unit configured to process the separator bottoms stream.

10. The processing facility of claim 9 , wherein at least a portion of the hydrogen produced in the hydrogen production system is supplied to the hydroprocessing system.

11. The processing facility of claim 9 , wherein the hydroprocessor separation system comprises a flash drum.

12. The processing facility of claim 9 , wherein the hydroprocessor separation system comprises a cyclonic phase separation device.

13. The processing facility of claim 9 , wherein the steam cracking system comprises a steam cracking furnace.

14. The processing facility of claim 9 , wherein the steam cracking system comprises a quench tower.

15. The processing facility of claim 9 , comprising a products separation system configured to separate product streams from the hydroprocessing system, or the steam cracking system, the heavy oil conversion unit, or any combinations thereof.

16. The processing facility of claim 15 , wherein the products separation system is configured to provide a raw hydrogen stream to the hydrogen production system.

17. The processing facility of claim 15 , wherein the products separation system is configured to provide a light hydrocarbon recycle stream to the steam cracking system.
