300ThousandTons/yearPropane Oxide Project 30万吨环氧丙烷项目初步设计说明书 Design Summary 1. ProjectIntroduction In 2012,Chinapropyleneproduction capacityreached 18million tons/ year （actualproduction 15 million tons / year), of which 75% is used to the product polypropylene. That is far below the world averageutilization levels, and thus speedingup variouspropylene down-stream product has becomeamajor issue for sustainabledevelopment olefin chemicalindustry . By combining H O production from anthraquinone and HPPO process, this project designs a 2 2 propylene utilization plant with main product of 300,000 tons/year PO and byproduct of 18,000 tons/year propylene glycol by annual consumption 236,000 tons of propylene. Based on the process of BASF/DOW, Evonik and Hunan pilot project technology, some technological innovations, including reactor design, separation process design, recycling byproducts has been developed,and striveto achievemaximum economic efficiency. Raw material utilization ratio of propylene is close to 100% with the principles of atom economy and green chemistry. HPPO technology is advanced, economical and environmentally friendly. Production process is divided into hydrogen peroxide production units and propylene oxide productionunits.Theprojecthasgreatprospectsfor development. 2.
