Using process software Aspen Plus of coal-fired power plant carbon dioxide capture flue gas pretreatment system simulation, studied the flue gas quantity、packing layer height、absorbent in quantity and absorbent in temperature, influence on the content of SO2 and cooling in the flue gas outlet. The results showed that the content of SO2 and temperature in the flue gas outlet, increase with increasing the flue gas quantity, decrease with increasing the packing layer height and absorbent quantity, increase with the rising of absorbent temperature.

Operating Pressure

Abstract Operation of power plants in carbon dioxide capture and non-capture modes and energy penalty or energy utilization in such operations are of great significance. This work reports on two gas fired pressurized chemical-looping combustion power plant lay-outs with two inbuilt modes of flue gas exit namely, with carbon dioxide capture mode and second mode is letting flue gas (consists carbon dioxide and water) without capturing carbon dioxide. In the non-CCS mode, higher thermal efficiencies of 54.06% and 52.63% efficiencies are obtained with natural gas and syngas. In carbon capture mode, a net thermal efficiency of 52.13% is obtained with natural gas and 48.78% with syngas. The operating pressure of air reactor is taken to be 13 bar for realistic operational considerations and that of fuel reactor is 11.5 bar. Two power plant lay-outs developed based combined cycle CLC mode for natural gas and syngas fuels. A single lay-out is developed for two fuels with possible retrofit for dual fuel operation. The CLC Power plants can be operated with two modes of flue gas exit options and these operational options makes them higher thermal efficient power plants.
