摘要
丙烯作为乙烯装置的重要产品之一,是聚丙烯装置的原料,丙烯中的甲醇是Unipol气相法聚丙烯装置的催化剂毒物,如果含量过高,会造成聚丙烯装置停车。根据自公司的实际案例,分析了SW工艺乙烯装置丙烯产品中甲醇是如何产生的,如何对丙烯中甲醇含量进行控制。
As one of important products of ethylene plant, propylene is a raw material for polypropylene device, methanol in propylene can cause catalyst poison in polypropylene unit with Unipol gas phase method. If the methanol content is too high, the polypropylene plant will be caused to stop. In this paper, according to the actual case, how to produce methanol in propylene products from ethylene unit with SW process was analyzed, how to control the methanol content in propylene was discussed.
