Patent ID: 8850787

Claim:
A hybrid thermal power generation system using crude oil as a fuel, the hybrid thermal power generation system comprising: a desalting apparatus for desalting the crude oil; an atmospheric distillation column for separating the crude oil desalted by the desalting apparatus into naphtha, light oil, and heavy oil; a combined cycle power generation system for generating power by driving a first gas turbine using the naphtha separated by the atmospheric distillation column as a fuel, a second gas turbine using the light oil separated by the atmospheric distillation column as a fuel, and a steam turbine with steam produced by utilizing exhaust heat from the first and second gas turbines; and a conventional power generation system for generating power by burning the heavy oil separated by the atmospheric distillation column in a boiler and driving a steam turbine with the steam produced by the boiler; wherein the fuels for the combined cycle power generation system and conventional power generation system are separated from the crude oil by using the atmospheric distillation column alone; and wherein a surplus of the naphtha for the first gas turbine or a surplus of the light oil for the second gas turbine is fed to the boiler of the conventional power generation system.
