The installation of the main equipment for Uhai Guangjin New Materials’ 300,000-ton BDO project is nearing completion

The source of calcium carbide for Wuhai Guangjin: In early July 2023, the first environmental impact assessment announcement was made for the first phase of this calcium carbide production project, with an annual capacity of 484,000 tons. This project was developed by Wuhai Guangjin New Materials Co., Ltd., and it is located in the Low-Carbon Industrial Park within the High-Tech Development Zone in Hainan District, Wuhai City, Inner Mongolia Autonomous Region. This marks the potential launch of yet another large-scale calcium carbide production project in Inner Mongolia. In addition, the BDO-PBAT integrated project of Wuhai Guangjin New Materials Co., Ltd. has also been approved for registration. The project will be constructed in two phases. In the first phase, a BDO production facility with an annual capacity of 300,000 tons will be built, along with 1 calcium carbide-acetylene plant with an annual capacity of 120,000 tons, 3 BDO (1,4-butanediol) plants, each with an annual capacity of 100,000 tons, and 3 formaldehyde (37%) plants, each with an annual capacity of 240,000 tons. In addition, utility systems and auxiliary facilities necessary to support these plants will also be installed. Phase 2: a project for producing 300,000 tons per year of biodegradable plastic (PBAT), comprising 5 sets of PBAT production facilities with a capacity of 60,000 tons per year each, along with the utility systems and auxiliary facilities required to support these facilities ； The 300,000 tons per year PBAT production facility in this project uses the transesterification method, with purchased purified terephthalic acid (PTA), adipic acid (AA), and BDO produced by upstream facilities as raw materials. The main product is PBAT chips, while the by-product is 32,000 tons per year of furan. The first-phase calcium carbide production project with an annual capacity of 484,000 tons, carried out by this company, is a supporting facility for the aforementioned project. It will involve the construction of 6 calcium carbide furnaces in 3 furnace workshops (each furnace having a capacity of 48,000 kVA), along with 3 new double-chamber lime kilns capable of handling 800 tons per day and 3 vertical drying kilns with a capacity of 20 tons per hour. Some existing factory foundations will be reused, and relevant auxiliary facilities will also be constructed. Inner Mongolia Chemical Industry observed that calcium carbide projects in Inner Mongolia have been included in the list of projects whose development is restricted; such projects can only be constructed through capacity replacement, in accordance with the \"Notice issued by the Inner Mongolia Autonomous Region Development and Reform Commission, the Department of Industry and Information Technology, and the Energy Bureau regarding the revision of <Several Guarantee Measures to Ensure the Achievement of the Energy Consumption Control Goals for the 14th Five-Year Plan>>.\" At that time, the announcement regarding this calcium carbide project indicated that Wuhai Haixin Chemical Co., Ltd., through a reduction and replacement ratio of 1.25:1, could provide 124,000 tons of calcium carbide capacity for the integrated production project for the BDO-PBAT new material industry chain. It also states that construction shall not commence without capacity replacement.
