发布时间：2019-08-02 19:56
【摘要】：针对全密度聚乙烯装置的排放至火炬的气体中含有1-丁烯和异戊烷等挥发性有机化合物,造成装置单耗增加的问题,参照国内现有装置的膜回收系统技术,对现有装置进行改造,在原有工艺流程中增设膜分离回收系统,采用膜分离技术对易冷凝的1-丁烯和异戊烷进行回收。结果表明:投用膜分离回收系统后,降耗效果显著,1-丁烯和异戊烷的回收率分别达到了71.32%,73.22%,消耗量降低了220.20,152.83 t/a,且渗透气中乙烯含量达到原料气的3倍多。
[Abstract]:In order to solve the problem of increasing unit consumption of volatile organic compounds such as 1-butene and isopentane in the gas emitted to the torch of the full density polyethylene plant, referring to the membrane recovery system technology of the existing plant in China, the existing plant is reformed, the membrane separation and recovery system is added to the original process, and the membrane separation technology is used to recover the condensation-prone 1-butene and isoamyl. The results showed that the consumption reduction effect was remarkable after the membrane separation and recovery system was used. The recovery rates of 1-butene and isoamyl were 71. 32% and 73. 22% respectively, the consumption was reduced by 22. 20152.83 t / a, and the ethylene content in osmotic gas was more than 3 times of that in raw material gas.
