Abstract

Climate change has become a prominent global issue due to human activities. One of the major green house gas emitting sources (CO 2) to the environment are considered as flue gases, which generated from process industries (coal and gas fired power plants, cement industry, etc.). In this study, a flue gas emission from a cement manufacturing process is considered for development of CO 2 capture plant. The cement industry emits approximately 5% of global man-made CO 2 emissions. Aspen Plus simulation tool is used for the development of the carbon capture model for three different removal efficiencies, 85%, 90% and 95%. Flue gas data related to the cement industry as well as process development parameters are taken from the literatures. Solvent concentration is varied from 25 to 40 (w/w %) and lean loading is varied from 0.15 to 0.35 (mole CO 2 /mole MEA) for 85-95 (mol %) CO 2 removal efficiency. Required re-boiler duties are calculated as 3229, 3306, and 3365 kJ/kg CO 2 (74, 80 and 86 MW) for 85%, 90% and 95% removal efficiencies, respectively.
