Since the traditional limestone-gypsum flue gas desulfurization will produce industrial waste slag desulfuration gypsum and CO2 off gas,a-gainst the carbon peak and carbon neutrality goals proposed in the"14th Five-Year Plan",it is not in line with the national strategy of ecological environ-mental protection,low-carbon emission reduction,resource utilization,circular economy,and sustainable development.In terms of product transforma-tion,environmental protection and resource utilization,the necessity of upgrade of limestone-gypsum flue gas desulfurization technology is analyzed,and it is proposed to upgrade it into ammonia-ammonium sulfate desulfurization technology and phosphate rock-phosphoric acid-phosphogypsum desulfurization technology,and specific upgrade measures and suggestions are proposed for different upgrade schemes.
