ABSTRACT:
The acceptability of residual oil as a gas turbine fuel is greatly enhanced in a two step process which significantly decreases the vanadium content of the residual fuel. In the process, the residual oil is first broken down into an oil phase and asphaltene phase by either conventional or supercritical extraction. In this step, the majority of vanadium remains in the asphaltene phase. The vanadium is then removed from the asphaltenes by a supercritical solvent extraction process in which the vanadium free asphaltene phase is then re-dissolved in the oil for use as a gas turbine fuel. This fuel possesses significantly lower vanadium content, and thus permits gas turbine operation for greater periods of time without maintenance.
