Abstract

See full text

A gas purification device removes a part of ammonia contained in a first gas; recovers a first off-gas containing the removed ammonia, removes hydrogen sulfide and ammonia from a second gas produced by removing the part of ammonia, recovers a second off-gas containing the removed hydrogen sulfide and ammonia, and combusts the first off-gas and the second off-gas. The gas purification device 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.
