Public notice on the acceptance of the environmental impact assessment report for Taizhou Xinpu Chemical’s high-end chemicals project, Xinpu Chemical (Taixing) Co., Ltd. Xinpu Chemical’s current projects cover the C2 and C3 industrial chains essentially. In 2023, Xinpu Chemical began construction of a PDH project with an annual capacity of 800,000 tons, capable of producing 800,000 tons of propylene per year ； The 1.1 million tons/year integrated light hydrocarbon processing plant still needs to sell 122,150 tons of propylene and 140,000 tons of ethylene as products each year. Therefore, Sinpu Chemical is currently planning to expand the downstream industrial chain for ethylene and propylene in order to produce polypropylene and butyl octanol, among other products. The enterprises located in the Taixing Economic Development Zone at Xinpǔ Chemical Industry have an annual demand of 400,000 tons for butyl octanol and around 80,000 tons for isobutyraldehyde. In the future, the demand for isobutyraldehyde is expected to rise to 200,000–250,000 tons per year, meaning that these enterprises in the zone will continue to have a stable demand for these substances. Xinpu Chemical has obtained the right to use 744.92 mu of land for construction in the industrial park through investment in plant upgrades and land bidding processes. In line with the company’s own development plans and the needs of the industrial park, Xinpǔ Chemical intends to build the Taizhou Xinpǔ Chemical High-End Chemicals Project on the aforementioned site (Xinpǔ Chemical Area G). Upon completion of the project, it will have an annual production capacity of 323,028 tons of syngas, 1,840 tons of hydrogen, 236,000 tons of n-butanol, 150,000 tons of isooctanol, 90,000 tons of isobutyraldehyde, 15,000 tons of heavy alcohols, 2,500 tons of sodium butyrate solution, 413,240 tons of n-butyraldehyde, 400,000 tons of polypropylene, 9,400 tons of argon (compressed or liquefied), 433,600 tons of nitrogen (compressed or liquefied), and 205,300 tons of oxygen (compressed or liquefied). In accordance with the latest requirements for by-product management, Sinpu Chemical plans to entrust qualified entities with the safe disposal of heavy alcohols and sodium butyrate as hazardous waste. Through the integration of chemical resources, industrial expansion, and product complementarity, this project aims to enhance the overall efficiency of the industrial chain, thereby reducing corporate costs and improving competitiveness. The integrated acrylic acid-butyl octyl alcohol-polypropylene industry chain enables efficient use of resources and cost competitiveness, in line with the trend toward integration and sophistication in the high-end chemical industry. Project Overview Project Name: Taizhou Xinpu Chemical High-End Chemicals Project ； Construction nature: New construction ； Construction location: Located in Taixing Economic Development Zone ； Total investment amount: 7,187.32 million yuan, of which 54.53 million yuan is invested in environmental protection, accounting for 0.76% of the total investment ； Land area: The newly acquired land in Area G of Xinpu Chemical covers 496,616 m2 (744.92 mu); the project itself occupies 216,361 m2, with 280,255 m2 set aside as reserve land ； Project category: Production of organic chemical raw materials, production of plastics and synthetic resins in their primary form ； Number of employees: The planned workforce for this project is 160 people ； Working hours: This project adopts a four-shift, three-shift production system, with 8 hours per shift. Production takes place for 333 days per year, resulting in a total annual working time of 8,000 hours ； Construction plan: The construction period for this project is 40 months. Product plan: Note that butyraldehyde, the product of this project, can be used to produce butanol or sold on the market, depending on market conditions. If all butyraldehyde is used to produce n-butanol, the production capacity for n-butanol would be 236,000 tons per year, while the production capacity for isooctanol would be 150,000 tons per year ； If all butylaldehyde is sold externally, the production capacity for butanol and isooctanol is 0; if some butanol is sold externally while some is used for its own production, then the production capacity for butanol is >0, 0
