Development of Carbon dioxide removal system from the flue gas of coal fired power plant

A quarter of the carbon dioxide emissions all over the world are exhausted from the thermal power plants. So we hav e been concentrated on the development of the low-cost CO2 capture technology. For the CO2 capture from the large amount of the flue gas, the chemical absorption method is suitable. We found an amine solvent had a good performance using thermodynamic simulation. The solvent exhibited that the CO2 recovery ratio and heat consumption for CO2 regeneration were 94% and 2.9 GJ/t-CO2 by the bench-scale test, respectively. Furthermore we will plan a 10 ton-CO2/day pilot plant using a real coal combustion gas.
