摘要：
Chlorine is a trace element in coal, which is released in the form of HCl gas in the combustion process. HCl has adverse effects on limestone-gypsum wet desulfurization facilities in coal-fired power units. The technology of HCl removal from coal-fired flue gas by alkaline absorbent was put forward based on chloride ion material balance in wet desulphurization absorber slurry. The technology of HCl removal was reviewed from the aspects of the types of alkaline absorbent, the effect of reaction conditions on HCl removal, and the mechanism of HCl removal. The research direction of removing low concentration HCl from coal-fired flue gas with alkaline absorbent was pointed out. © 2021, Chemical Industry Press Co., Ltd. All rights reserved.
