国内丙烷脱氢制丙烯现状及发展

Present Situation and Development of Propane Dehydrogenation to Propylene in China

近年来国内丙烯工业产能增长迅速,在新增产能中,传统石化工艺占比明显下降,丙烷脱氢作为专产丙烯技术,优势明显,产能逐年增加。国内建设的丙烷脱氢主要采用Lummus的Catofin固定床工艺和UOP的Oleflex移动床工艺,汇总了国内运行和建设中的丙烷脱氢项目及产能情况。分析了影响丙烷脱氢效益和发展的因素,总结了未来丙烷脱氢的发展方向。

In recent years,the production capacity of domestic propylene industry has increased rapidly.In the new production capacity,the proportion of traditional petrochemical process has decreased significantly.Propane dehydrogenation,as a special propylene production technology,has obvious advantages and the production capacity has increased year by year.The domestic propane dehydrogenation mainly adopts the catofin fixed bed process of Lummus and the oleflex moving bed process of UOP,which summarizes the propane dehydrogenation projects and production capacity in domestic operation and construction.The factors affecting the benefit and development of propane dehydrogenation were analyzed,and the development direction of propane dehydrogenation in the future was summarized.
