Recently, the first public notice regarding public participation in the environmental impact assessment for the second phase of the Xinjiang Guotai Xinhua coal-based fine chemical circular economy industrial park project was released. The second phase of the Guotai Xinhua coal-based fine chemicals circular economy industrial park is located in the Western Industrial Park of Wucaiwan, within the Western Industrial Cluster Area of the Zhundong Economic and Technological Development Zone in Xinjiang, and was built on the vacant land reserved at the original site of Guotai Xinhua’s first-phase project. The project produces acetylene and formaldehyde using dry acetylene units and formaldehyde units, generates hydrogen through methanol cracking, and further produces BDO via the alkyne-aldehyde method. Upon completion, it will produce 100,000 tons of BDO per year, with 1,200 tons of butanol as a by-product. The construction scope includes the installation of an acetylene generation unit, a formaldehyde production unit, a 1,4-butanediol (BDO) production unit, a hydrogen production unit via formaldehyde cracking, a high-concentration salt waste incineration unit, and an evaporation crystallization unit for this project; in addition, auxiliary facilities such as a refrigeration station, a foam preparation station, and a heat exchange station will also be built.
