HETMOC · Highly Efficient Tubular Membranes for Oxy-Combustion

This project will develop and demonstrate Highly Efficient Tubular Membranes for OxyCombustion. Oxycombustion is a promising option for implementing cost-efficient carbon capture and sequestration (CCS) in future coal fired power plants. The use of oxygen membranes in the process has the potential to significantly reduce the efficiency losses associated with the capture and to improve the overall process economy. The multinational consortium behind the proposal includes industry as well as research centers, combining between them all the multi-disciplinary competences needed to carry out the project. The partners are: Risoe National Laboratory for Sustainable Energy (coordinator; DK), Forschungszentrum Julich GmbH (D), Fraunhofer IKTS (D), VITO (B), SINTEF (N), Air Liquide(Fr), Saint Gobain CREE (Fr) and INABENSA (ESP).Two different types of tubular oxygen transport membranes will be developed at the research centres participating in HETMOC, and the technology for producing the membranes will be transferred to an industry partner that will demonstrate membrane production by industrial processes. The fabricated membranes will be demonstrated over a period exceeding 1000 hours in a pressurized Proof of Concept module so as to address critical issues related to the practical operation. The module will hold 25 tubes of 1 m length. The knowledge obtained in both the development and fabrication of the membranes will, together with the experiences from the Proof of Concept module, be used for a conceptual design of an industrial scale module with a capacity of 100 tons per day. The cost of such a module will be assessed and an overall techno-economical evaluation of various ways of integrating oxygen transfer membranes in the power plant will be carried out to estimate the efficiencies of various schemes and to identify the most rewarding (in terms of overall cost and efficiency) routes for further development.
