摘要
When realizing CSS steam power plants based on oxy-combustion, the energy demand for oxygen production is one of the main causes for efficiency losses. This comparative study focuses on the impact of the air separation technology-cryogenic as well as high temperature membrane based-on the efficiency of a coal-fired oxyfuel steam power plant.. As a result of this study both show comparable efficiency potentials whereas the membrane based technology needs a higher degree of integration into the power cycle to compete efficiencies of the oxyfuel power plant with cryogenic ASU.
