氯丙烯生产尾气资源化处理工艺研究

Research on Resource Utilization Treatment Process of Tail Gas from Chloropropylene Production

丙烯高温氯化法生产氯丙烯过程副产大量氯化氢气体,并与未反应的丙烯以混合气体的形式排出,丙烯和氯化氢的分离工艺、处理成本对氯丙烯经济学有很大影响。基于此,叙述了一种简单清洁、可工业化的混合气分离技术,实现了丙烯的回收循环和氯化氢的资源化利用,以显著改善企业经济效益。

The high-temperature chlorination process of propylene produces a large amount of hydrogen chloride gas as a byproduct,which is discharged in the form of a mixed gas with unreacted propylene.The separation process and treatment cost of propylene and hydrogen chloride have a significant impact on the economics of chloropropene.Based on this,a simple,clean,and industrializable mixed gas separation technology is described,which realizes the recovery and recycling of propylene and the resource utilization of hydrogen chloride,significantly improving the economic benefits of enterprises.
