The 600,000-ton/year coal-to-olefins project of Qinghai Mining, located in the industrial park of Golmud City in Haixi Prefecture, is set to begin construction next spring; currently, the bidding process for PMC and EPC services for this project is underway. The total investment in this project is 21.1 billion yuan. Using coal from the Yuka, Dameigou, and Muli coal mines as raw material, it employs technologies such as pressurized gasification of coal and methanol-to-olefins to produce 600,000 tons per year of products such as ethylene and polypropylene, as well as by-products like sulfur, methyl tert-butyl ether (MTBE), and butylene. The main components of the project include 10 units such as air separation, pulverized coal gasification, shift reaction, low-temperature methanol washing, methanol synthesis, methanol to olefins (MTO), olefin conversion, polypropylene production, MTBE/butene-1 production, and sulfur recovery. Complementary facilities include thermal power stations, circulating water systems and other auxiliary projects, storage and transportation facilities such as coal silos and chemical storage tanks, as well as environmental protection systems for wastewater treatment and reuse.
