Patent number: 7895822Abstract: A power generation system includes at least one turbine system. The turbine system includes a compressor section comprising at least one stage, configured to supply a compressed oxidant and a combustion chamber configured to combust the compressed oxidant and a fuel stream comprising carbon-based fuels and to generate a hot flue gas. The turbine system further includes an expander section having an inlet for receiving the hot flue gas comprising at least two stages. The two stages include a high-pressure expander configured to generate an expanded exhaust gas rich in CO2. The high-pressure expander fluidly coupled to a low-pressure expander configured to generate a final exhaust and electrical energy. A CO2 separation system is fluidly coupled to the high-pressure expander for receiving the expanded exhaust gas from the high-pressure expander and providing a CO2 lean gas that is then fed to the low-pressure expander.Type: GrantFiled: November 7, 2006Date of Patent: March 1, 2011Assignee: General Electric CompanyInventors: Stephanie Marie-Noelle Hoffmann, Michael Bartlett

Patent number: 7827778Abstract: Power plants and process for lowering CO2 emissions generally includes extracting a portion of the recirculated CO2-rich flue gas mid-way through the compression pathway of a gas turbine and removing the CO2 in a separation unit. The remaining portion of the CO2 rich flue gas (i.e., the portion of the recirculated flue gas that was not fed to the separation unit) is mixed with fresh air coming from an additional compressor-expander and then fed back to the compression pathway. As a result, flue gas recirculation increases the CO2 concentration within the working fluid, leading to an additional increase in CO2 partial pressure. As the concentration and partial pressure of CO2 is increased, a lower energy penalty is observed to remove the CO2. Moreover, a reduced volume is fed to the CO2 separation unit during operation. Consequently, the size of the separation equipment can be reduced as well as the energy required for the separation process.Type: GrantFiled: November 7, 2006Date of Patent: November 9, 2010Assignees: General Electric Company, STATOILInventors: Matthias Finkenrath, Michael Bartlett, Arne Lynghjem, Jon Jakobsen
