According to the approval document issued by the Ministry of Ecology and Environment on the environmental impact assessment report for Xinjiang Shanneng Chemical Co., Ltd.’s 800,000 tons per year coal-to-olefins project in Zhundong Wucaiwan, the project is located in the Zhundong Economic and Technological Development Zone in Changji Hui Autonomous Prefecture, Xinjiang Uygur Autonomous Region. It uses coal as raw material and employs processes such as pressurized coal gasification, purification, methanol synthesis, and coal-to-olefins conversion; green hydrogen is also utilized in this process. The project involves the construction of an facility with an annual production capacity of 800,000 tons of olefins. The project is designed to consume 3.9021 million tons of raw coal per year and 412,300 tons of fuel coal per year (this figure will decrease to 233,900 tons per year after 5 years of green hydrogen integration). Additionally, it requires 7.1064 million cubic meters of fresh water annually (this amount will drop to 6.673 million tons per year after 5 years of green hydrogen integration). The main components of the project include 13 production units such as air separation, gasification, shift reaction and heat recovery, low-temperature methanol washing, sulfur recovery, methanol synthesis, methanol to olefins, olefin separation, steam cracking, C4 to 1-butene conversion, polyethylene production, polypropylene production, and water electrolysis plants ； Auxiliary engineering includes power stations, water supply and drainage systems, flare systems, etc ； Storage and transportation engineering includes coal transportation and storage systems, tank farms, and product warehouses, etc ； Environmental protection engineering mainly includes waste gas treatment facilities, wastewater treatment facilities, and solid waste treatment facilities.
