Project Name: Yichuan County Industrial Park Investment, Development and Construction Co., Ltd.’s 100,000-ton-per-year 1,4-butanediol production project. Launch date: October 28, 2025. Location: Shaanxi Province. Industry/project type: Chemicals and pharmaceuticals/Chemical raw materials and chemicals/Chemical raw materials. Project owner: Yichuan County Industrial Park Investment, Development and Construction Co., Ltd. Total investment: 1.9 billion yuan. Current progress: Project registration completed. Construction location: An area of 100 mu north of Niujia Dian in Yan’an City, Shaanxi Province. Scope of construction: The production capacity of the BDO facility in this project is set at 100,000 tons per year; in addition, there will be a 40,000-ton-per-year facility for producing acetylene from natural gas, a 100,000-ton-per-year facility for producing methanol (using acetylene off-gas recovery), and a 200,000-ton-per-year facility for producing formaldehyde (37%). The annual operating time is 8,000 hours in each case. BDO mainly supplies downstream facilities such as PBS series polyesters and PTMEG. Excess acetylene feedstock can be supplied to the alkyne alcohol plant, while excess methanol is sold externally. The project involves the construction of a facility with an annual production capacity of 100,000 tons of BDO (including units for acetylene, methanol, and formaldehyde), with a total investment of 1.9 billion yuan. Progress milestone: 2025-10-27. It was recently learned that the project has been registered (project registration). On 2025-05-21, the project to produce 100,000 tons of 1,4-butanediol was approved by the Shaanxi Development and Reform Commission (project registration)
