摘要： To provide a gas clean-up unit and a gas purification method that can effectively reduce the concentration of carbonyl sulfide in gas to be treated even when the concentration of carbonyl sulfide in the gas to be treated is high. A gas clean-up unit 1 includes a first COS converter 12 that performs a first conversion process of converting hydrogen cyanide contained in gas to be treated G 1 to ammonia, in presence of a first catalyst and at a first predetermined temperature; a second COS converter 14 that performs a second conversion process of converting carbonyl sulfide in gas to be treated G 3 after the first conversion process to hydrogen sulfide, in presence of a second catalyst and at a second predetermined temperature that is lower than the first predetermined temperature; a first cleaner 13 that performs a cleaning process of cleaning and removing ammonia by bringing gas to be treated G 2 into gas-liquid contact with cleaning liquid; and a desulfurizer 16 that absorbs and removes hydrogen sulfide in gas to be treated G 5 by bringing the gas to be treated G 5 after the cleaning process into gas-liquid contact with absorbent.

摘要： A gas purification device includes; an ammonia removal part configured to remove a part of ammonia contained in a first gas; a first off-gas recovery part configured to recover a first off-gas containing ammonia removed by the ammonia removal part; a hydrogen sulfide/ammonia removal part configured to remove hydrogen sulfide and ammonia from a second gas produced by removing the part of ammonia by the ammonia removal part; a second off-gas recovery part configured to recover a second off-gas containing hydrogen sulfide and ammonia removed by the hydrogen sulfide/ammonia removal part; and a combustion part configured to combust the first off-gas and the second off-gas. The combustion part includes: a first combustion chamber in which combustion is performed in a reducing atmosphere; a second combustion chamber in which combustion is performed in a reducing atmosphere downstream of the first combustion chamber; and a third combustion chamber in which combustion is performed in an oxidizing atmosphere downstream of the second combustion chamber. The first off-gas flows into the first combustion chamber, and the second off-gas flows into the third combustion chamber.
