Abstract
A novel power generation system, more specifically an integrated power generation and air separation system and an integrated power generation and air separation process is provided. A key component of the system and process is an oxygen-fired combustor designed for gas turbine operating pressures. The combustor produces a high-temperature gas stream that enters one or more heat exchangers to generate/heat steam, and then enters one or more turbines to generate power. The steam from the heat exchanger drives one or more steam turbines to generate power, and the discharged steam is admitted to the combustor. To maximize cycle efficiency, steam extraction and reheat is incorporated in the process. Additional power is generated from a high-pressure nitrogen stream produced by an air separation unit (ASU). This process has the potential to attain high cycle efficiencies with zero emissions, while utilizing existing or near-term steam turbines, and moderate-pressure combustion systems.
