On January 29, the signing ceremony of the contract for the contract for the two invention patent technologies and engineering designs by the Southwest Research and Design Institute of Chemical Engineering and Sichuan Tianyi Science and Technology Co., Ltd. and the 400,000-ton/year DME industrial device built in Ningxia Baota Group was held in Chengdu. Held. This is currently the world's largest gas-phase dimethyl ether industrial plant, marking a new breakthrough for China in this field. Large-scale production will play an important demonstration role for the large-scale promotion of dimethyl ether.
According to reports, the Pagoda Group has conducted extensive research and investigations on dimethyl ether technologies and markets at home and abroad, and exchanged views with well-known scientific research institutions at home and abroad. Finally, Southwest Branch and Tianke Group were recognized for their advanced, reliable and mature technologies. . The project is expected to invest 120 million yuan, plans to put into operation by the end of 2008.
The project will use methanol gas-phase catalytic dehydration method to produce dimethyl ether, with a unique vaporization decanter structure and a simple process design of the separation process, which can save 30% of investment, and can greatly reduce energy consumption, so that the steam consumption per ton of product than The domestic and foreign devices of the same type are 0.5 tons lower; with self-developed catalysts, the selectivity of methanol to dimethyl ether will reach 99.5% or more, and it can basically reach no exhaust emissions, and the methanol consumed per ton of product will be reduced.
More than 10 years ago, the Southwestern Institute took the lead in the establishment of several sets of gas-phase methanol-dehydrated kiloton-grade aerosol-grade and 10,000-ton-grade fuel-grade dimethyl ether industrial plants in companies such as Guangdong Zhongshan Fine Chemicals Co., Ltd., currently using Southwestern Institute and Tianke Group. The invention patent technology of ether has established more than 40 sets of dimethyl ether devices at home and abroad. All the technical and economic indicators meet or exceed the design requirements. The dimethyl ether content is 99% to 99.9% and the product yield is as high as 98%.
