CO2 RECOVERY APPARATUS AND RECOVERY METHOD OF CO2 ABSORPTION SOLUTION

摘要

PPROBLEM TO BE SOLVED: To provide a COSB2/SBrecovery apparatus for reducing the discharge amount of a COSB2/SBabsorption solution accompanying a COSB2/SBremoval exhaust gas, reducing COSB2/SBabsorption solution components supplied to a lean solution and improving the recovery efficiency of the COSB2/SBabsorption solution further, and a recovery method of COSB2/SBabsorption solution. PSOLUTION: The COSB2/SBrecovery apparatus 10A relating to this embodiment has an absorption tower 1006 for removing COSB2/SBfrom a COSB2/SB-containing gas 1002A and a regeneration tower 1007 for regenerating a rich solution 1008 and reuses the lean solution 1009 from which COSB2/SBis removed in the regeneration tower 1007 in the absorption tower 1006. A demister 1015 for water flush disposed to the absorption tower 1006 is a demister composed of an at least two-layer structure of high pressure loss, and the catching efficiency of COSB2/SBabsorption solution mist and washing water mist accompanying the COSB2/SBremoval exhaust gas 1002B is improved.
