[0002] Desulfurization generally refers to the process of removing sulfur from fuel before combustion and before flue gas emission. It is one of the important technical measures to prevent and control air pollution. There are generally three desulfurization methods: desulfurization before combustion, desulfurization during combustion, and desulfurization after combustion. Reducing SO2 pollution has become a top priority for today's atmospheric environmental governance. Many flue gas desulfurization processes have been widely used in industry, and they also have important practical significance for the treatment of exhaust gases from various boilers and incinerators.
