Summary Summary SSuummmmaarryy Abstract Abstract AAbbssttrraacctt Our team designs a branch plant producing DME for the head office. The scale of the plant is 100 thousand tons per year, using gas-direct technology with metal-zeolite bi-functional catalyst. The plant is located inthe city ofWuxiofJiangsu Provincewhere is nearthe market place. 1. BackgroundandSignificanceofDMEProduction 1. BackgroundandSignificanceofDMEProduction 11..BBaacckkggrroouunnddaannddSSiiggnniiffiiccaanncceeooffDDMMEEPPrroodduuccttiioonn Theprices ofthe naturalgas and LPG are growing dueto the growing price of crude oil. China is facing the pressure of energy provision and this situation will last for long time. It is believed that developing coal- based substitutable energy is key strategy to decrease the large dependenceonoil and reducethe impactbrought byrapid pricegrowth of international energy and bulk raw materials oneconomic development of China. There have been fundamentals and developing space for coal- basedmethanoland aetherfuels inChina andDME injected dieseloil and LPG are the main substitutive products. DME, one of clean and high efficiency products, has been placed into national new energy and reproducible develop plans and mainly utilized for substitution for city fuel gas and diesel oil for cars. It is highly believed that the substitution ofDME foroil products notonly fully expandsthe energy advantages of China butalso exhibitsstrategic objective. 1 6 1 6 11 / 66 2. Designedtechnology 2.
