<p>PURPOSE:To obtain the CO2 treating plant capable of immobilizing the net CO2 without causing environmental problems by using an igneous rock as the source for CaO as the CO2 immobilizing agent. CONSTITUTION:An igneous rock 2 as the fixing agent is packed in a vessel 1 to cause a CO2 immobilizing reaction. An inlet duct 3 and an outlet duct 4 are connected to the vessel 1, and a blower 6 connected to a duct 5 is connected to a control valve 8 through a duct 7 and further to the inlet duct 3. When a CO2-contg. gas is brought into contact with the igneous rock in the vessel 1, an immobilizing reaction is caused between CO2 in the gas and CaO in the igneous rock, and the CO2 is absorbed by the igneous rock. Since the reaction is exothermic, the heat energy is recovered with the reaction part as a heat exchanger structure.</p> |
