Recently, the concrete pouring for the foundation of the gasification framework in this demonstration project was finished. The project is located in the Tongxin Industrial Park of Xinjiang Shengxiong Energy Development Co., Ltd., in Alehui Town, Toksun County, Xinjiang. It makes full use of the characteristics and advantages of coal chemical processing; by utilizing the waste gas generated as a by-product of the semi-coke production facilities operated by Zhongtai Group in Toksun County, along with the residual materials such as coke dust and coal fines, it converts low-value materials into raw materials for production, thereby increasing their added value and extending the industrial chain. The implementation of this project will help promote the efficient utilization and transformation of the existing local coal deep-processing industry resources. The gasification unit project for the Sino-Thai project was constructed by the Northwest Branch of 16th Chemical Construction Company; a total of 4,396 cubic meters of concrete was poured for the foundation of the unit’s framework. The completion of the concrete pouring for the foundation of the gasification framework in the gasification unit marks a significant breakthrough in this project’s key milestones, laying a solid foundation for the subsequent construction work. Xinjiang Zhongtai New Materials Co., Ltd. is located in Toksun County, Turpan City, Xinjiang. It was established with joint investment from Xinjiang Zhongtai (Group) Co., Ltd. and Xinjiang Zhongtai Chemical Co., Ltd., with Zhongtai Group holding 40% of the shares and Zhongtai Chemical holding 60%. The current status of the comprehensive utilization of coal, based on its grading and quality classification in Toksun County, mainly involves the production of semi-coke through coal carbonization, with tar and waste gas as by-products. Among these, coal tar is refined through hydrogenation, while the excess waste gas is mostly used as fuel; its calorific value is recovered only, and it is released into the atmosphere through flaring, resulting in resource waste and environmental pollution. The existing by-product coke dust and coal powder are utilized at low value as thermal coal. The existing coal processing industry is primarily at the primary stage, with a short industrial chain. Within the industrial layout of the Yila Lake Industrial Park and Tongxin Industrial Park in Toksun County, Zhongtai Group operates a coal carbonization plant with an annual production capacity of 2.7 million tons, as well as another plant run by Shengxiong Energy with an annual production capacity of 750,000 tons. Both of these plants are owned by Zhongtai Group. Currently, these facilities produce a total of 143,000 Nm3/h of waste gas, 660,000 tons of coke dregs per year, and 800,000 tons of coal powder per year. “During the 14th and 15th Five-Year Plans period, Zhongtai Group has planned a total production capacity of 1.67 million tons per year for BDO, which requires approximately 810,000 tons of methanol per year; meanwhile, the planned production of acetic acid and its further processed products will also require a certain amount of methanol. At present, other existing and under-construction BDO projects in Xinjiang all require the purchase of methanol, such as Xinjiang Guotai Xinhua, Xinjiang Lanshan Tunhe, Xinjiang Xinye Group, etc., which also lays a foundation for the development of the methanol market. Based on the industrial development requirements of Zhongtai Group, the needs of the methanol market in Xinjiang, as well as the existing industrial advantages of Zhongtai Group in Toksun County, and in line with relevant industrial policy requirements, it is planned to construct a 1 million tons per year methanol production facility in the Tongxin Industrial Park of Toksun County. The raw materials for this facility will be the waste gas generated in Zhongtai Group’s own factories, along with various residues such as coke dust and coal powder. This project will be carried out by Zhongtai New Materials. The project uses waste gas and screenings (coke dust and coal powder) as raw materials, with an annual production capacity of 100,000 tons for Baisheng Lita and 18,900 tons for Sikeli Xu. The main components of the facility include gasification units, purification units, sulfur recovery units, and methanol synthesis units. In addition, auxiliary facilities such as administrative office buildings, gas protection and fire stations, warehouses, circulating water stations, desalinated water stations, liquid storage areas, and cargo handling areas are constructed. Environmental protection facilities such as flares, sewage treatment plants, accident containment tanks, and temporary storage areas for hazardous waste are also built. The total investment for the project is 5,990.53 million yuan, of which 244.592 million yuan is allocated to environmental protection measures, accounting for 4.1% of the total investment.
