Modelling Of CO2 Capture Using Aspen Plus For Coal Fired Power Plant

Abstract

Many industrial power plants burn fossil fuels to get their energy while releasing flue gases to the atmosphere. Greenhouse gases are responsible for global warming and which causes severe environmental impacts. Carbon dioxide capture from the coal-fired power plant is important to maintain a better clean environment. The Post-combustion chemical absorption process is the most viable option to capture Carbon dioxide from industrial flue gases. The carbon dioxide capture model is developed and implemented in Aspen Plus process simulation software to calculate the required re-boiler energy demand. The required re-boiler energy demand is increasing when CO2 content of the flue gas is decreasing. The re-boiler energy is calculated as 3481, 3620, 3840 kJ/kg CO2 for the 85, 90 and 95% CO2 removal process for flue gases from EDF CHP power plant, Krakow, Poland.
