日前,丙烯双氧水制环氧丙烷工业生产装置在长炼开工建设。丙烯双氧水制环氧丙烷生产工艺技术由长炼自主开发,装置建设预计投资12.8亿元,设计产能为10万t/a,属于全球第一套。环氧丙烷是除聚丙烯和丙烯腈之外的第三大丙烯衍生物,是重要的基本有机化工合成原料,主要用于生产聚醚、内二醇等。下游产品近百种,广泛用于汽车、建筑、食品、烟草、医药及化妆品等行业。现有的环氧丙烷生产技术存在污染环境、腐蚀设备的问题,且联产副产物量大、工艺冗长、设备投资大、原子利用率
Recently, propylene hydrogen peroxide propylene oxide industrial production plant in the long refining started construction. Propylene oxide hydrogen peroxide propylene oxide production technology developed by the long refining, plant construction is expected to invest 1.28 billion yuan, design capacity of 100,000 t / a, is the world’s first set. Propylene oxide is the third largest propylene derivative besides polypropylene and acrylonitrile. It is an important basic organic chemical synthesis raw material, mainly used in the production of polyether, internal glycol and so on. Nearly 100 kinds of downstream products, widely used in automotive, construction, food, tobacco, pharmaceutical and cosmetics industries. The existing propylene oxide production technology has the problem of environmental pollution and corrosion of equipment, and the co-production byproduct is large, the process is lengthy, the equipment investment is large, the atom utilization rate
