The largest acetic acid production complex in the northwest sees increased capacity utilization 2025-09-22 On September 17, the integrated plant of Xinjiang Zhonghe Hezhong New Materials Co., Ltd., located in the Circular Economy Industrial Park in the southern part of the Hami High-Tech Industrial Development Zone, which is capable of producing 1 million tons of acetic acid and its derivative products per year, continued to operate at high efficiency. With a total investment of 5 billion yuan, since its commissioning on September 3, batches of high-quality acetic acid have been shipped in tankers to chemical enterprises in Jiangsu, Zhejiang and other regions, marking the full entry into capacity-expansion phase of the largest acetic acid integrated production base in the northwest region. “Since its commissioning, the plant has been operating at full capacity; the purity of the products produced reaches 99.96%, while the ** standard is 99.8%, meaning it exceeds the standards for first-class products. ”Fu Pengjie, the person in charge of the acetic acid production unit at Xinjiang Zhonghe Hezhong New Materials Co., Ltd., said that the project is operating smoothly at present, with a daily output of around 600 tons. This project utilizes a domestically leading low-pressure carbon-based synthesis process for ultra-low-water methanol production; through key related technologies, coal is converted into high-purity carbon monoxide, which is then used in a carbonation reaction to produce acetic acid. As an important organic chemical raw material, acetic acid is widely used in the production of downstream products such as PTA (pure terephthalic acid) and EVA (ethylene-vinyl acetate copolymer). Once the project is fully operational, its annual output value will exceed 3 billion yuan. It will not only help alleviate the shortage of acetic acid and acetic anhydride in the northwest region but also, through its leading role, attract more downstream enterprises to settle in Hami, with the potential to develop a industrial chain worth hundreds of billions in value, covering acetic acid, its derivatives, and end products. Since being designated as a **strategic base for coal-based oil and gas production in March 2021, Hami City has leveraged its high-quality coal resources, with predicted reserves of 570.8 billion tons (characterized by a high oil content and excellent quality), to develop a complete industrial chain that includes coal-to-methanol production, coal tar processing, and the production of ethylene glycol from waste gas. At present, the total investment in 8 large-scale coal chemical projects under construction or planned in this city exceeds 100 billion yuan. These projects cover various fields such as coal-to-oil and gas production, fine chemicals, and new materials, and the coal processing capacity is continuously increasing. By the end of the 14th Five-Year Plan period, Hami’s annual coal processing capacity is expected to exceed 50 million tons, providing strong support for ensuring **energy security.
