Heavy oil reforming method, an apparatus therefor, and gas turbine power generation system
First Claim
Patent Images
1. A method of operating a gas turbine which comprises:
- providing a heavy oil containing at least one of vanadium and sulfur;
reacting said heavy oil with water which is heated to 300°
C. to 500°
C. and pressured to 10 MPa to 30 MPa by utilizing the heat of exhaust gas from said gas turbine, and then bringing said heavy oil, along with said water, into contact with a scavenger for scavenging vanadium and/or sulfur in the heavy oil to thereby eliminate vanadium and/or sulfur from the heavy oil, thereby producing a reformed oil suitable for said gas turbine, wherein the vanadium concentration of said reformed oil is reduced to 0.1 ppm or less; and
supplying said reformed oil to said gas turbine.

Abstract
A heavy oil reforming method which reforms a heavy oil to give a fuel suitable for a gas turbine, eliminates sulfur and vanadium, i.e., harmful components, from a heavy oil, and enables almost all the hydrocarbons in the heavy oil to be used in gas turbine combustion; an apparatus therefor; and a gas turbine power generation system using the reformed heavy oil as fuel is disclosed. The method includes reacting a heavy oil with supercritical water and then with a scavenger for sulfur and vanadium to eliminate sulfur and vanadium from the heavy oil.

-
providing a heavy oil containing vanadium; reacting said heavy oil with water, which is in a state of being heated to 300°
C. to 500°
C. and pressured to 10 MPa to 30 MPa by utilizing the heat of exhaust gas from said gas turbine, and then scavenging the vanadium contained in the heavy oil in the form of vanadium oxide to thereby eliminate vanadium from the heavy oil, thereby producing a reformed oil suitable for said gas turbine, wherein the vanadium concentration of said reformed oil is reduced to 0.1 ppm or less; andsupplying said reformed oil to said gas turbine.
