硫化物在石化产品中普遍存在,对于石化产品工艺、性能,操作人员安全和环境保护影响较大。含硫量的控制及硫化物的脱除技术,既是目前炼油及化工工艺过程中的研究热点,也是石化产品环保研究中的重要内容。本文综述以轻烃和溶剂油为代表的两类石化产品的脱硫技术进展,简述轻烃和溶剂油中主要的硫化物分布情况,回顾含硫量控制的相关标准,总结目前常用的脱硫技术,展望新型脱硫技术的进展和动向。
Sulfides exist widely in petrochemicals and have considerable influences on the processing parameters and the product quality of petrochemicals. Sulfides also affect the safety of the operating personnel and the environment. The controls of the sulfide content and the desulfurization technologies are currently the research focus in both petroleum industry and related environmental protection fields. This paper reviews the progress in the desulfurization technology of the light hydrocarbon and the solvent oil. The major forms of the sulfides in the light hydrocarbon and the solvent oil are discussed, together with the related control measures of the sulfide content. The commonly used desulfurization technology is reviewed. Progress and developing trends of the novel desulfurization technology are commented.
