OTM Based Oxy-fuel Combustion for CO2 Capture

developing an optimum process configuration for integrating Oxygen Transport Membranes (OTMs) into a power generation process allowing for high efficiency Carbon Dioxide (CO2) capture from coal power plants under a three year Cooperative Agreement (DE-FC26-07NT43088). The main objective of Phase I is to develop OTM technology that meets commercial targets for oxygen flux, strength and reliability. A second objective of Phase I is to down-select an optimum process integration cycle for the OTM membranes with CO2 capture and to provide a full system and economic analysis of that cycle. An advanced porous support for the membrane separation layers was developed in collaboration with ENrG, Inc. (Buffalo, NY) in a project funded by NYSERDA (agreement number: 10080), preliminary tests revealed that this advanced support allowed significantly higher oxygen flux than the standard support material. When combined with further improvements to the fuel oxidation layer, oxygen transport rates that approach commercial targets were demonstrated at the laboratory scale
