Sustainable Mining and Metallurgy

This paper analyzed the off-gas generation situation of domestic waste incineration, compared the local emission standards, national standards and international standards of waste incineration off-gas. Combined with the application of desulfurization technology in domestic projects, this paper also analyzed and compared the principles, influencing factors, equipment, advantages and disadvantages of semi-dry desulfurization, dry desulfurization and wet desulfurization technologies, as well as the problems existing in projects. According to different off-gas characteristics and environmental protection emission requirements, semi-dry, dry and wet desulfurization processes can be combined to achieve better results, however, how to choose the appropriate desulfurization technology to lower the investment and operation cost is still being explored.
