DETERIORATION PREDICTING METHOD OF DENITRATION CATALYST, DETERIORATION COUNTERMEASURES METHOD, DETERIORATION COUNTERMEASURES SYSTEM, AND DESIGN METHOD OF EXHAUST GAS TREATMENT SYSTEM

摘要

PROBLEM TO BE SOLVED: To predict an active deterioration of denitration catalyst in a denitration system for exhaust gas or the like.

SOLUTION: In an exhaust gas treatment in which an ammonia-based substances is added to exhaust gas from a combustion equipment 102 to perform decomposition of nitroxide by a denitration catalyst 104, deterioration of the denitration catalyst 104 by a sulfur oxide is predicted based on a relationship between at least temperature and an oxidation ratio of the sulfur oxide.
