The company’s first and second MTP units were put into operation in 2010 and 2014 respectively. Each MTP unit is designed with a capacity of 500,000 tons per year, while the dimethyl ether production section has a capacity of 1.2 million tons per year; these are the largest dimethyl ether production facilities in China that utilize foreign process technologies. Winning the bid once again demonstrates that the dimethyl ether catalyst produced by Southwest Chemical can fully replace foreign products, laying a solid foundation for Southwest Chemical to become a catalyst supplier that is leading in China and renowned worldwide. In 2012, the CNM-3 dimethyl ether catalyst produced by Southwest Chemical Industry partially replaced the imported products (50%) used by Ningxia Olefins Company. Through continuous research and innovation, in 2016 and 2019, domestic catalysts were fully used in the dimethyl ether production units of the two MTP plants at Shenhua Ningmei Olefins Company, replacing imported products. This marked a complete success in the localization of catalysts for million-ton-scale dimethyl ether production plants, thereby breaking the monopoly held by foreign products in this market. The application results show that under full-load operation of the MTP unit, the CNM-3 dimethyl ether catalyst exhibits excellent performance in all aspects, meeting all the design specifications of the unit; its service life exceeds 3 years, and its performance parameters are at the international advanced level.
