Carbonylation reactor for Inner Mongolia Zhuozheng Coal Chemical’s 600,000 tons/year ethanol project installed
Thread Content
According to Shaanxi Huajian, on November 15, 2025, Shaanxi Huajian Lifting Company successfully completed the first lifting task for the 600,000 tons per year ethanol production project at Inner Mongolia Zhuozheng Coal Chemical Industry – namely the lifting of the carbonylation reactor. This marked the official entry of the project construction into a new phase of equipment installation. The carbonylation reactor weighs 656 tons, has a diameter of 6.1 meters, and a height of 19.4 meters. Shaanxi Huajian is responsible for constructing the dimethyl ether synthesis, carbonylation, hydrogenation, product separation, compression, and heating furnace units of the 600,000 tons per year ethanol plant. The 600,000-ton ethanol production facility in Inner Mongolia Zhuozheng utilizes the patented syngas-to-ethanol (DMTE) technology jointly developed by the Dalian Institute of Chemical Physics of the Chinese Academy of Sciences and Shaanxi Yanchang Petroleum Group, with design work carried out by Beijing Petrochemical Engineering Company. The Inner Mongolia Zhuozheng Coal Chemical project focuses on the optimized deep processing and comprehensive utilization of methanol and acetic acid in order to produce high-end chemicals and new materials. It includes facilities for the pretreatment of 3 million tons per year of raw coal, as well as plants for producing 1 million tons per year of methanol, 500,000 tons per year of acetic acid, 600,000 tons per year of ethanol, 350,000 tons per year of methyl glycolate (MG), 200,000 tons per year of polyglycolic acid (PGA), 60,000 tons per year of polyoxymethylene (POM), and LNG facilities; in addition, there are various supporting infrastructure and auxiliary systems.
The Zhuozheng coal chemical project is scheduled to enter the full installation phase in 2026 and come online for operation in 2027. The Inner Mongolia Zhuozheng methanol and acetic acid project is located in the Nalinhe Industrial Park of the Sulihe Economic Development Zone in Wushen Banner. It covers an area of approximately 7,500 mu, with a total estimated investment of 59 billion yuan. Building on the existing facilities that can produce 1.2 million tons of methanol and 1 million tons of acetic acid per year, this project involves on-site investigations and technical exchanges with 53 entities, including design institutes, patent holders for process technologies, and manufacturing companies. In line with industry guidelines aimed at promoting greenness, low carbon emissions, energy conservation, and environmental protection, advanced technologies such as efficient and clean comprehensive utilization of coal based on its different quality levels, large-scale pulverized coal gasification, fixed-bed hydrocracking, technologies developed by the Dalian Institute of Chemical Physics for converting methanol into ethanol and formaldehyde into methyl glycolate, as well as polyglycolic acid production techniques from Shanghai Pujing, are being employed. The project will be constructed in two phases and four stages, with an expected production volume of 110.15 million tons by 2027, and a total output of 2.6–3.2 million tons of new material products by 2030. It produces 19 types of products, including methanol, acetic acid, vinyl acetate (VAC), ethanol, formaldehyde, polyoxymethylene (POM), polyglycolic acid (PGA), ethylene-vinyl acetate copolymer, methyl valerate, mixed alcohols, polyglycolic acid oligomers, sulfur, coal tar, upgraded coal, liquefied natural gas (LNG), liquefied petroleum gas (LPG), naphtha, and special diesel. Through subsequent processes such as chain extension, chain supplementation, chain solidification, and chain strengthening, more than 30 types of products can be manufactured, thereby enabling the development of coal chemical projects in a manner that features higher quality, greater diversity, and lower carbon emissions. Planned construction period: May 2023 to December 2030. Construction location: Nalinhe Industrial Park, Sulihe Economic Development Zone, Wushen Banner, Ordos City. Construction contents: Build a demonstration project for new materials with an annual production capacity of 2.6 million tons. The main products will be: 1 million tons per year of polyglycolic acid (PGA), 500,000 tons per year of ethylene-vinyl acetate copolymer (EVA), 100,000 tons per year of polyvinyl alcohol (PVA), 120,000 tons per year of polyoxymethylene (POM), 50,000 tons per year of ethanol, 730,000 tons per year of acetic acid, and 50,000 tons per year of vinyl acetate ； By-products: 40,000 tons/year of mixed alcohols, 80,000 tons/year of polyglycolic acid oligomers ； Complementary facilities include water, electricity, gas, and steam supply systems from the park to the factory premises, as well as utility systems and auxiliary facilities such as air separation units, thermal power systems, raw material storage and transportation systems, and wastewater treatment facilities for various types of raw water. Additionally, there are service-related facilities and living amenities, as well as ash disposal areas. The estimated investment for the first phase of the project is 25.5 billion yuan. Building on the existing facilities that produce 1.2 million tons of methanol and 1 million tons of acetic acid per year, this phase takes into account efficient and clean utilization of coal at different levels, as well as advanced processing techniques to enhance the value of products derived from methanol and acetic acid. By integrating green energy sources, the project aims to produce more than 30 types of main and auxiliary products, including acetic acid, ethanol, polyglycolic acid, and polyoxymethylene. The annual output value is expected to be around 11.7 billion yuan. The first phase is scheduled to begin operations in October 2026, with construction of the second phase starting simultaneously. The long-term plan covers an area of approximately 7,800 mu, with an estimated investment of 59 billion yuan, aiming to enter the market for high-end fine chemical products in the fields of new energy and new materials.
