At the fourth academic seminar held recently by the Technical Committee of Chemical Fertilizers and Catalysis of the Shaanxi Provincial Chemical Society and the Fourth Conference of the Shaanxi Coal Conversion Research Society, He Yongde, Chairman of the Shaanxi Provincial Chemical Engineering Society, suggested that the methanol to olefins should be large-scale, and the state should Pay close attention to building industrial demonstration devices.
According to reports, the replacement of naphtha with methanol as raw material and the production of low-carbon olefins (ethylene, propylene) through MTO, DMTO, and MTP processes have become hot topics at home and abroad. The United States, Germany, and China have accelerated the process of industrialization. Among them, the DMTO technology is a national key scientific and technological key technology with independent intellectual property rights undertaken by Dalian Institute of Chemicals, China. In August 2006, it completed the world's first 15,000-ton/year industrial test in Shaanxi Province and passed the national scientific and technological achievements appraisal. The results show that the methanol conversion rate is greater than 99.42%, the ethylene + propylene selectivity is greater than 79.21%, and the scale and technical indicators are in the leading position in the world.
He Yongde said that China's imports of petroleum and olefin products have increased rapidly. The foreign dependence rate is close to 45% and 50% respectively. The market demand for low-carbon olefins is huge and the self-sufficiency rate is low. It is expected that the demand for ethylene and propylene will still be 7% in the next 15 years. 8% speed increase. Therefore, the state should give strong support to methanol-based low-carbon olefins, make unified plans, develop in an orderly manner, and pay close attention to the construction of large-scale industrial demonstration plants; the scale of methanol and olefins should be 1.8 million tons and 600,000 tons/year respectively; they must be built on coal resources. Rich areas to reduce production costs; in accordance with the requirements of the circular economy, planning and construction of the coal-methanol-olefin-thermoelectric upstream and downstream integration model. At the same time, the project has a large amount of water, and it is recommended to adopt new water-saving technologies such as air cooling and rational use of water resources.
