It was recently reported that the 60,000 tons per year polyoxymethylene production project of Xinjiang Xinlianxin Energy and Chemical Co., Ltd. has entered its peak construction phase. To date, 90% of the equipment installation has been completed, and 30% of the process piping installation has been completed. Xinjiang Xinlianxin has introduced international advanced technologies for the production of 60,000 tons of polyoxymethylene, aiming to build high-end polyoxymethylene production lines. Xinjiang Xinlianxin currently has multi-nozzle gasification plants for the production of ammonia, methanol, and urea, as well as 2 melamine production units (with a total capacity of 120,000 tons). Project Overview: 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 development; 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 refined methanol production line will be built. Due to the severe overcapacity of methanol production in the country at present, the construction unit has decided to expand into downstream industries by establishing new production lines for formaldehyde, polyformaldehyde, dioxolane, as well as polymerization processes and auxiliary facilities within the plant. The methanol that was previously intended for sale will be used to produce polyformaldehyde, thereby achieving a production capacity of 60,000 tons per year of polyformaldehyde resin and improving the overall economic efficiency of the enterprise. Xinjiang Xinlianxin Energy and Chemical Co., Ltd. currently has multi-nozzle gasification plants for the production of ammonia, methanol, and urea, as well as 2 sets of melamine production facilities (with a total production capacity of 120,000 tons). Project Name: 60,000 tons/year Polyoxymethylene Project of Xinjiang Xinxin Heart Energy and Chemical Co., Ltd.
Project Owner: Xinjiang Xinxin Heart Energy and Chemical Co., Ltd.; Project Type: New construction; Total Investment: The total investment amounts to 1,647,480,000 yuan, of which 67,400,000 yuan is allocated to environmental protection measures, accounting for 4.09% of the total investment; Labor Force and Working Hours: The project will create 148 new jobs, with continuous production carried out using a four-shift, three-shift system, resulting in an annual working time of 8,000 hours; Location of Construction: Tahe Industrial Park, Manas County, Changji Prefecture, Xinjiang, within the premises of Xinjiang Xinxin Heart Energy and Chemical Co., Ltd.; Construction Period: 26 months. Construction contents: Upon completion, the project will be capable of producing 60,000 tons per year of polyoxymethylene. It consists mainly of the main plant, utility and auxiliary facilities, storage and transportation systems, as well as environmental protection measures. The main plant includes a formaldehyde production unit using the iron-molybdenum process, a dioxolane (DoX) unit, a trioxymethylene (TOX) synthesis unit, as well as polymerization and post-treatment units. The auxiliary facilities include heat exchange stations, a central control room, and upgrades to the existing desalination station. The storage and transportation systems comprise raw material storage tanks and product warehouses. The supporting facilities include office buildings, a central laboratory, water supply systems, and air supply systems.
