In the paper the results of the thermodynamic and economic analysis of the supercritical coal fired power plant integrated with the carbon dioxide capture installation was shown. The paper presents the algorithm for determining the power of power plant and its efficiency losses due to the membrane separation of CO2 from the flue gases and CO2 compression. For the purpose of separating CO2 a membrane technology was applied. Calculations concerning the membrane separation of CO2 were carried out with the program Aspen. For the assessment of the separation process two indices were applied: the mole fraction of CO2 in the permeate and the recovery ratio of CO2. The decision variables in the calculation were the pressure on the feed side and on the permeate side. The pressure on the permeate side is generated by a vacuum pump and on the feed side by a compressor. The power rating of require components determines the energy consumption of the separation and compression processes. The way of determining the minimum losses of the power rating and efficiency of the power plant in membrane separation process and compression CO2 using calculated indices were shown. The power rating losses and efficiency of the power plant were determined for both processes. The economic analysis was calculated for power unit, taking into account investments and costs connected to the CO2 capture installation. For the conducted analysis it is essential to determine the unit sale price of electricity as well as the cost of avoided emission CO2.
