초록 ▼

A method and apparatus for upgrading a petroleum feedstock with supercritical water are provided. The method includes the steps of: (1) heating and pressurizing a petroleum feedstock; (2) heating and pressurizing a water feed to above the supercritical point of water; (3) combining the heated and pressurized petroleum feedstock and the heated and pressurized water feed to produce a combined feed; (4) supplying the combined feed to a hydrothermal reactor to produce a first product stream; (5) supplying the first product stream to a post-treatment process unit to produce a second product stream; and (6) separating the second product stream into a treated and upgraded petroleum stream and a water stream.

대표청구항 ▼

1. A system for upgrading a petroleum feedstock, the system comprising: a petroleum feedstock;a water feed;means for heating and pressurizing said petroleum feedstock and water feed, wherein said means for heating and pressurizing the water feed are operable to produce a supercritical water;a first hydrothermal reactor, said first hydrothermal reactor in fluid communication with the petroleum feedstock and water feed, and being operable to maintain a reactor temperature and pressure sufficient to maintain water in its supercritical state;a second hydrothermal reactor, said second hydrothermal reactor in fluid communication with an outlet of the first hydrothermal reactor, wherein the second hydrothermal reactor is maintained at a temperature between 100° C. and 300° C., wherein water present in the second hydrothermal reactor is maintained in a liquid phase; anda separator in fluid communication with an outlet of the second hydrothermal reactor, said separator configured to separate water and hydrocarbon containing liquids. 2. The system of claim 1 wherein the first hydrothermal reactor is maintained at a temperature greater than about 400° C. 3. The system of claim 1 further comprising the step of maintaining the second hydrothermal reactor at a temperature and pressure such that water is in a sub-critical state. 4. The system of claim 1 further comprising the step of maintaining the second hydrothermal reactor at a temperature of between about 120 and 200° C. 5. The system of claim 1 wherein hydrogen is not supplied to the second hydrothermal reactor. 6. The system of claim 1 wherein the second hydrothermal reactor further comprises a post-treatment catalyst. 7. The system of claim 6 wherein the post-treatment catalyst includes an active species selected from the group consisting of the Group VIB, and Group VIIIB elements. 8. The system of claim 6 wherein the post-treatment catalyst is a desulfurization catalyst. 9. The system of claim 1 wherein the first hydrothermal reactor is in the absence of an external source of hydrogen gas. 10. The system of claim 1 wherein the first hydrothermal reactor is in the absence of an externally supplied catalyst. 11. The system of claim 1 wherein the ratio of petroleum feedstock to water feed is between about 2:1 to 1:2. 12. The system of claim 1 wherein the residence time of the petroleum feedstock and water feed in the first hydrothermal reactor is between 1 second and 120 minutes. 13. The system of claim 1 wherein the residence time of the petroleum feedstock and water feed in the second hydrothermal reactor is between 2 minutes and 30 minutes.
