SOLID CO2 ADSORBENT MATERIAL SYSTEM

摘要

An object of the present invention is to provide a solid CO2 adsorbent material system, which recovers CO2 using a solid adsorbent material and enables efficient heat recovery and reduction in the amount of heat used. A solid CO2 adsorbent material system includes: a boiler which burns a fossil fuel to generate steam and exhaust gas; steam turbines which are driven by the steam; a condenser which condenses the steam after driving the steam turbines; a deaerator and feed water heaters which heat water condensed by the condenser using steam of the steam turbines; and a packed tower in which a solid adsorbent material for adsorbing CO2 is placed and CO2 in the exhaust gas is adsorbed by the solid adsorbent material when the exhaust gas is supplied thereto. To the packed tower, water condensed by the condenser is supplied as a heat transfer medium. The water as a heat transfer medium transfers heat to the solid adsorbent material in a non-contact manner to cool the solid adsorbent material having CO2 adsorbed thereon, and then is discharged from the packed tower and supplied to the feed water heaters or the deaerator.
