A recently granted patent (Publication Number: US11885266B2) discloses a steam cycle system designed for plant systems. The system includes components such as a fuel feed line, expansion turbines, separators, heat exchangers, and compressors to efficiently generate high-pressure steam for power generation. The system also integrates an air separation unit to supply oxygen to the fuel mixture, enhancing combustion efficiency. Additionally, a CO2 cycle system is incorporated to manage emissions, further improving the environmental sustainability of the plant operations.

The patent also outlines a method for operating the plant system, involving steps such as separating nitrogen from air to produce oxygen, expanding exhaust flows in turbines, cooling and separating liquid and gas compositions, and utilizing high-pressure steam for power generation. The method includes conducting a CO2 cycle on the exhaust gases to reduce emissions and enhance overall efficiency. By returning a portion of the exhaust gas to the heat exchanger unit and utilizing compressors for gas compression, the method aims to optimize energy utilization and minimize environmental impact. Overall, the patented system and method offer a comprehensive approach to steam cycle operation in plant systems, emphasizing efficiency, sustainability, and emission reduction.
