为提高乙烯收率,齐鲁石化公司1999年实施了将丙烷与乙烷混合共裂解的技术,效果显著。据初步分析,乙烯收率提高了0.2%。传统乙烯生产技术均以石脑油或SSOT尾油等为裂解原料,但该公司烯烃厂工程技术人员研究发现,如果把用作燃料气或液化气的丙烷送进裂解炉,与其它原料一起进行裂 To improve the yield of ethylene, Qilu Petrochemical Company in 1999 implemented a total of propane and ethane co-cleavage technology, the effect is significant. According to preliminary analysis, ethylene yield increased by 0.2%. Traditional ethylene production techniques are naphtha or SSOT tailings as cracked raw materials, but the company olefin plant engineering and technical personnel found that if the propane used as fuel gas or liquefied gas into the cracking furnace, along with other raw materials crack
