Recently, the environmental impact assessment document for Xinjiang Heshan Juli Chemical Co., Ltd.’s project was approved, with an investment of 466.4 billion yuan and an annual production capacity of 400,000 tons. The project uses coal as a raw material and coal slurry technology to produce hydrogen and carbon monoxide, which serve as feedstocks for synthesizing MD. The hydrogen chloride, a by-product of MD, is absorbed and then used in a new Wood electrode process to produce chlorine, which is employed as a feedstock for MDI. The MDI produced serves as a raw material for polyurethane elastomers. Xinjiang Heshan Juli Chemical Co., Ltd.’s 400,000 tons/year MD project: Project background – The project is located in the Kuidong Special Industry Park within the Kuqiong-Dushanzi Economic and Technological Development Zone, on the premises of Xinjiang Heshan Juli Chemical Co., Ltd. MDI (diphenylmethane diisocyanate) is produced using coal, methanol, benzene, and other raw materials. The production capacity is 400,000 tons per year. The total investment for the project is approximately 4,663.89 million yuan, of which 292.35 million yuan is allocated to environmental protection facilities, accounting for about 62.7% of the total investment. Xinjiang Heshan Juli Chemical Co., Ltd. is a wholly-owned subsidiary of Yantai Juli Fine Chemicals Co., Ltd., registered in Kuitun City. It is located within the Kuidong Special Industrial Park. At present, there are 4 projects under construction on the site: the project for the front area of Xinjiang Heshan Juli Chemical Co., Ltd. The environmental impact assessment for this project was approved by the Environmental Protection Bureau of the Kuitun-Dushanzi Economic Development Zone on May 15, 2014 (Document No. Kuidu Huan Han 19) ； Xinjiang Heshan Juli Chemical Co., Ltd.’s 150,000 tons per year TD (toluene diisocyanate) production project received approval from the Environmental Protection Department of the Xinjiang Uyghur Autonomous Region on July 8, 2015 (Document No. Xin Huan Han 774) ； The tar recovery project of Xinjiang Heshan Juli Chemical Co., Ltd. received approval from the Environmental Protection Department of the Xinjiang Uyghur Autonomous Region on January 16, 2017 (Document No. Xin Huan Han 107) ； The waste acid concentration project of Xinjiang Heshan Juli Chemical Co., Ltd. received approval from the Environmental Protection Department of the Xinjiang Uyghur Autonomous Region on January 16, 2017 (Document No. Xin Huan Han [2017]108). The main components of this project include: the core processing facilities (a gas production unit with a capacity of 43,000 cubic meters per hour, an Hc-oDC production unit with an annual capacity of 200,000 tons, a sulfuric acid concentration unit, a nitric acid production unit with an annual capacity of 200,000 tons, and an MDI production unit with an annual capacity of 400,000 tons); as well as storage and transportation facilities (storage areas for raw materials and finished products, including areas for benzene, methanol, liquid ammonia, NaOH, and MDI finished products) ； The intermediate tank area includes storage tanks for concentrated sulfuric acid, aniline, 31% hydrochloric acid, liquid chlorine, 37% formaldehyde, chlorobenzene, etc. The necessary engineering facilities include 10 new circulating water towers with a capacity of 5,500 cubic meters per hour, a desalination plant with a capacity of 650 cubic meters per hour, air separation and air compression units, 1 circulating fluidized bed boiler with a capacity of 240 tons per hour, a refrigeration plant, as well as an expansion of the plant’s comprehensive wastewater treatment facility and a system for recycling treated wastewater. There are also other utility systems and auxiliary facilities.
