<P>PROBLEM TO BE SOLVED: To provide a system for recovering carbon dioxide from an exhaust gas where required energy for removing moisture from the exhaust gas is reduced and carbon dioxide is efficiently recovered. <P>SOLUTION: The system 10 for recovering carbon dioxide comprises a sublimator 35 to recover carbon dioxide, lines L1, L2, L3 and L4, lines L10a, L10b, L11 and L12, heat exchangers 13, 15, a condenser 16 and dryers 20, 24 to further remove moisture contained in the exhaust gas. The dryers 20, 24 have a moisture adsorbing agent (active alumina) adsorbing moisture in the exhaust gas and being regenerated by releasing adsorbed moisture with heat. A line L13 to supply the exhaust gas passed through the heat exchangers 13 and a line L14 to return the exhaust gas passed through the dryers 20, 24 to the line L12 are located for regenerating the moisture adsorbing agent with heat. <P>COPYRIGHT: (C)2010,JPO&INPIT |
