摘　　要：冶炼烟气中富含大量的硫资源,如何有效回收利用该资源一直是行业的研究方向。新型的可再生胺法脱硫技术对冶炼烟气中二氧化硫进行提取,然后冷冻液化制备液态二氧化硫,该工艺一方面保证了处理后烟气的达标排放,另一方面成功将回收后的硫资源转化为高附加值产品。基于这两方面的优点,这一工艺越来越多的成为烟气中硫资源回收技术的选择。Smelting flue gas is rich in a large amount of sulfur resources. How to effectively recycle this resource has been the research direction of the industry. The new renewable amine desulfurization technology extracts sulfur dioxide from the smelting flue gas, and then freezes and liquefies to prepare liquid sulfur dioxide. This process on the one hand ensures that the flue gas meets the emission standard, on the other hand, it successfully converts the recovered sulfur resources to a high value-added product. Based on the advantages of these two aspects, this process has increasin.
