Estimating the term…
In a method for producing gas turbine fuel through the step of modifying heavy fuel oil with the use of an asphaltene-insoluble solvent, the utilization factor of the heavy fuel oil usable as gas turbine fuel is increased by making asphaltene selectively removable. A solvent having a specific inductive capacity in the range of 1.4 to 2.0 is used as the asphaltene-insoluble solvent. In particular, water controlled in temperature and pressure so as to have a specific inductive capacity in the above range is used as the asphaltene-insoluble solvent. By using such a solvent, an asphaltene component contained in the heavy fuel oil can be selectively removed and power generation can be performed while utilizing 95% or more of the heavy fuel oil.
A system for generating electric power by a gas turbine which is driven by using, as gas turbine fuel, components of heavy fuel oil obtained by bringing the heavy fuel oil into contact with an asphaltene-insoluble solvent and removing an asphaltene component, wherein said system includes an asphaltene removing unit for performing an asphaltene removing process in which the heavy fuel oil is brought into contact with an asphaltene-insoluble solvent having a specific inductive capacity in a range of 1.4 to 2.0.
