Preliminary Research of a Zero CO₂ Emission Power Generation System

CO₂ is a main greenhouse gas fazing the Earth. So countries around the world are actively studying the methods of capturing CO₂ to reduce emission. In this paper, firstly a brief review was carried out on the research development and technical problems of three typical near-zero CO₂ emission power generation systems. Focus was made on the construction of one possible commercially applied zero emission system, which has new principle but relatively conservative sections. Preliminary analysis and calculation of energy and mass flow have been finished to evaluate its performance. The results showed that apart from zero CO₂ emission, a relatively tempting efficiency could be sustained. Theoretically, higher than 90% purity of CO₂ and 63% generation efficiency of the whole system can be achieved.
