| Abstract: | The cause of the strong odor and serious pollution from the HPF ammonia desulphurization process was analyzed based on the actual situation of the desulfurization unit of the Shaanxi Coke Chemical Co., Ltd. Pertinent corrective measures for various sections that caused such pollution were proposed. It pointed out that by adopting centralized treatment of the emitted gas, using better corrosion- resisting materials, optimizing the cooling mode of the pumps, and selecting highly efficient filters and heat exchangers, the environmental pollution problem caused by the desulfurization unit could be solved effectively. The paper recommended two-stage absorption process for the complete coking and chemical recovery area. |
