    摘要: A high carbon content membrane and method for making the same are disclosed. The carbon membrane includes an asymmetric hollow filamentary carbon membrane, including a partial carbonization product of an asymmetric hollow filament including an aromatic imide polymer material. The carbon membrane is at least 95 weight percent carbon, and has a dense layer located in the outside surface portion of the hollow filamentary membrane and a porous base layer continued from the dense layer and located in the inside portion of the hollow filamentary membrane. A process for separating CO2 from natural gas is described including: contacting a mixture of CO2 and natural gas with a first side of a carbon membrane in a manner to cause a portion of the mixture to pass through the carbon membrane to a permeate side. The resulting mixture on the permeate side becomes enriched in CO2 over that of the mixture on the first side. The contacting step occurs at a pressure of at least about 200 psia.

    摘要: The present invention generally relates to power generation systems configured to absorb and capture a component, such as carbon dioxide, in a flue gas for later sequestration or utilization, wherein heat generated in the sorption process is captured for use in the power generation system. In some examples, the heat of sorption is used to preheat fluids in one or more systems of the power generation system to reduce the heating load on the subsystem. By using the heat of sorption, the carbon dioxide capture and sequestration process not only reduces or eliminates the concentration of carbon dioxide in the flue gas, but reduces or eliminates the parasitic effect of carbon dioxide capture and sequestration on power generation.
