GAS SEPARATING RECOVERY APPARATUS AND GAS SEPARATING RECOVERY METHOD

摘要

PROBLEM TO BE SOLVED: To appropriately separate and recover a nitrogen oxide in mixed gas while attaining the miniaturization of an apparatus.

SOLUTION: This gas separating recovery apparatus 20 separating and recovering the nitrogen oxide from the mixed gas that contains at least the nitrogen oxide includes a storage means (a tank 21) storing an absorption liquid that absorbs the nitrogen oxide; a gas-liquid contact means (a gas-liquid contactor 24) bringing the absorption liquid stored in the storage means, into contact with the mixed gas; and a liquid recovery means (recovery piping 25 and a recovery container 26) for recovering the absorption liquid after brought into contact with the mixed gas by the gas-liquid contact means. The absorption liquid is an ionic liquid that chemically absorbs the nitrogen oxide.
