Public announcement on the environmental impact assessment for Xinjiang Haoyuan Chemical’s project to invest 3.64 billion yuan in upgrading its production capacity to 600,000 tons per year of ethanol produced from syngas
Thread Content
An investment of 3.64 billion yuan has been allocated for the construction of a new synthetic gas plant with a capacity of 600,000 tons in Xinjiang; announcement issued on 2025-10-27. On October 23, the environmental impact assessment documents related to the construction of this project, which aims to adjust the production structure by manufacturing ethanol from 600,000 tons of synthetic gas per year, were made public. Xinjiang Haoyuan Chemical Co., Ltd. plans to eliminate the facilities for producing synthetic ammonia, urine-based fertilizers, high-nitrogen water-soluble compound fertilizers, and melamine in Phase II of the low-carbon integrated project that combines photovoltaic hydrogen production with clean utilization of resources, and instead build facilities for producing ethanol from 600,000 tons of syngas per year. The syngas-to-ethanol project utilizes the raw gas from Phase II of Xinjiang Haoyuan Chemical Co., Ltd.’s low-carbon integrated project for photovoltaic hydrogen production coupled with clean utilization of resources. Through conversion, acid gas removal, and deep cryogenic separation of CO, CO gas is produced; this CO, along with purchased methanol, is used to manufacture acetic acid via the low-pressure carbonylation of methanol technique. Ethyl acetate is produced from acetic acid and ethanol using the esterification method, while ethanol is produced by the hydrogenation of ethyl acetate. The main units of the project include coal gasification, shift reaction, acid gas removal, sulfur recovery, deep cryogenic separation of CO, hydrogen product purification, acetic acid, ethyl acetate, ethanol production units, as well as auxiliary and supporting facilities. New facilities for CO cryogenic separation, hydrogen product purification, acetic acid, ethyl acetate, and ethanol will be constructed this time. Gasification, shift reaction, acid gas removal, sulfur recovery, and some of the auxiliary facilities are part of Xinjiang Haoyuan Chemical Co., Ltd.’s low-carbon integrated project that combines photovoltaic hydrogen production with clean utilization of resources. The gasification furnace for this project is based on a 2,000 t/d capacity space-based furnace from Xinjiang Haoyuan Chemical’s low-carbon integrated project for the clean utilization of resources through photoelectrochemical hydrogen production. The project includes 1 set of acetic acid production equipment. The capacity is 800,000 tons per year. Choose the domestic methanol low-pressure carbonylation technology for acetic acid production. It includes synthesis, distillation, absorption, and catalyst units. Ethyl acetate utilizes the ethyl acetate technology provided by Jiangmen Huajie Information Consulting Co., Ltd. Ethanol is produced using the ethyl acetate indirect method. The capacity is 600,000 tons per year.
Project Overview: Project Name: Xinjiang Haoyuan Chemical Co., Ltd.’s Project to Adjust the Product Structure by Producing 600,000 tons of ethanol from syngas per year. Nature of the project: New construction project. Contractor: Xinjiang Haoyuan Chemical Co., Ltd. Location: The factory is situated in the Beisantai Circular Economy Industrial Park in Jimsar County, covering an area of 109,812 m2. This project is located within the site of Xinjiang Haoyuan Chemical Co., Ltd.’s low-carbon integrated project for the clean utilization of resources through photoelectrochemical hydrogen production. The geographical coordinates of the project site are 88°45′25.331″ east longitude and 44°8′21.559″ north latitude. Construction content: This project uses raw crude gas as input; through a conversion unit, an acidic gas removal unit, and a CO cryogenic separation unit, CO gas is produced. CO is combined with purchased methanol to produce acetic acid using the low-pressure carbonylation process for acetic acid production. Acetic acid and ethanol are used to produce ethyl acetate via esterification, and ethyl acetate is then hydrogenated to produce ethanol. The main production units of this project include a coal gasification unit, a shift unit, an acid gas removal unit, a sulfur recovery unit, a CO cryogenic separation unit, a hydrogen product purification unit, an acetic acid unit, an ethyl acetate unit, an ethanol unit, as well as auxiliary facilities. Among them, the newly built CO cryogenic separation unit, hydrogen product purification unit, acetic acid plant, ethyl acetate plant, and ethanol plant ； The gasification unit, shift unit, acid gas removal unit, sulfur recovery unit, and some auxiliary facilities are part of Xinjiang Haoyuan Chemical Co., Ltd.’s low-carbon integrated project for the clean utilization of resources through photoelectric hydrogen production. After the completion of this project, the construction of the 400,000 tons per year ammonia synthesis plant, the 500,000 tons per year urine (intermediate product) production plant, the 500,000 tons per year high-nitrogen water-soluble compound fertilizer production plant, the 200,000 tons per year diesel engine exhaust cleaner production plant, the 120,000 tons per year melamine production plant, and the 100,000 tons per year food-grade CO production plant as part of the second phase of Xinjiang Haoyuan Chemical Co., Ltd.’s low-carbon integrated project for the clean utilization of resources through photovoltaic hydrogen production, will be discontinued. Construction timeline: The project is scheduled to begin construction in July 2025 and go into operation in July 2027. Project investment: The total investment for this project is 3,643.05 million yuan, of which 195.60 million yuan is allocated to environmental protection measures, accounting for 5.36% of the total project investment. Labor quota: The total labor quota for the entire factory is 300 people, of which 270 are production workers and 30 are technical management staff. Production system: The production workshop operates on a four-shift, three-shift system ； There are 333 working days per year, with an annual operating time of 8,000 hours.
