As a new type of material, polyoxymethylene is one of the five major engineering plastics; it is known as \"super steel\" and is widely used. Developing the polyoxymethylene project in conjunction with the ethylene glycol project offers inherent advantages; it is possible to make full use of the high-quality formaldehyde produced as an intermediate product in the ethylene glycol process, as well as low-cost facilities such as those used for common utilities. By extending the industrial chain in this way, it is possible to fully leverage the advantages of the products, the company, and costs. Through proper planning and scientific design, the added value of the products can be increased. The project is located in the industrial park of Tuoketuo County, Hohhot City, Inner Mongolia, with a total land area of 40,300 m2. This project involves the construction of a production facility capable of producing 60,000 tons of polyoxymethylene per year. The facility will be located to the northeast of the ethylene glycol storage area. The main components of the construction include a formaldehyde concentration unit (with a capacity of 9×104 tons per year), a trioxymethylene production unit (with a capacity of 6×104 tons per year), a dioxolane production unit (with a capacity of 0.375×104 tons per year), and a polyoxymethylene production unit (with a capacity of 6×104 tons per year) ； The supporting utility facilities and auxiliary production facilities include: substations, finished product warehouses, control rooms, water supply and drainage systems, and other such auxiliary production facilities, with the rest relying on the ethylene glycol plant located outside the boundary area. The project investment is 1,569.91 million yuan.

Recently, the environmental impact assessment document for Xinjiang Xinlianxin Energy Chemical Co., Ltd.’s 60,000 tons per year polyoxymethylene production project was approved by the Department of Ecology and Environment of the Xinjiang Uyghur Autonomous Region. Xinjiang Xinlianxin Energy and Chemical Co., Ltd. is located in the Manas River Industrial Park. It is a wholly-owned subsidiary of Henan Xinlianxin Chemical Industry Group Co., Ltd. The company invested 2.75 billion yuan in the initial phase of its operations; it uses raw coal from the Manas Tianli and Tianxin coal mines to build a facility capable of producing 280,000 tons of synthetic ammonia, 480,000 tons of urea, 100,000 tons of melamine, and 150,000 tons of compound fertilizers per year. The investment in environmental protection measures amounted to 117.721 million yuan, representing a proportion of 4.35% of the total investment. Later, optimizations and upgrades will be carried out on the basis of the 280,000 tons/year ammonia synthesis and 480,000 tons/year urea production facilities; the existing shift and methanol washing units will be modified, and a 150,000 tons/year high-purity methanol production line will be built.
