Embodiment Construction

[0016] The high-efficiency power generation method of the present invention will be described below with reference to an embodiment shown in the accompanying drawings.

[0017] figure 1 is a schematic diagram showing the layout of an embodiment of a system for separating crude oil or heavy oil by distillation of a system for implementing the high-efficiency power generation method of the present invention by using an exhaust gas reburning system;

[0018] The distillation equipment of this embodiment includes a heater 1 , a vacuum distillation column 2 and a steam ejector 3 .

[0019] The heater 1 as a device for heating crude oil or heavy oil heats crude oil or heavy oil by heat exchange between steam and crude oil or heavy oil. Steam is supplied from a boiler (not shown). The steam obtained from the boiler is sent to a steam turbine to turn it, thereby generating electricity. The steam supplied to the heater 1 is the steam which once rotated the steam turbine to generate ...

Abstract

In a high-efficiency power generating method to generate electric power by an exhaust gas re-combustion system using at least a gas turbine, a boiler, and a steam turbine, crude oil or heavy oil is heated with steam obtained from the boiler; the crude oil or heavy oil is distilled under reduced pressure; and electric power is generated by using an obtained light oil fraction as a gas turbine fuel and by using a heavy oil fraction as a boiler fuel.

Description

technical field [0001] The invention relates to a high-efficiency power generation method. Background technique [0002] In recent years, power plants have conducted research on the fractionation of crude oil or heavy oil. Light oil fractions (low boiling point components) obtained by fractional distillation are sent to a gas turbine where they are combusted to generate electricity. The high-temperature combustion exhaust gas obtained by the gas turbine is sent to a boiler instead of air, and the heavy oil fraction (high-boiling point components) is burned in the boiler, and a steam turbine is rotated by the high-temperature, high-pressure steam generated in the boiler to generate electricity. That is, there is provided a method in which power generation is performed simultaneously with so-called re-powering in which exhaust gas from a gas turbine is charged into a boiler and recombusted. [0003] As a means of distilling crude oil or heavy oil, atmospheric and vacuum dist...
