Recently, the Yantai Ecology and Environment Bureau issued approval decisions regarding the environmental impact assessment documents for several projects of Wanhua Chemical. A total of four projects were approved this time, namely the project for upgrading production capacity to 25,000 tons per year of high-end TPU using special isocyanates, the project for producing 40,000 tons per year of polyether amine, the project for producing 60,000 tons per year of polyester polyols, and a nutrition products project.
Project 1: Project Name – Technical upgrade project for producing 25,000 tons per year of high-end TPU using special isocyanate types. Project Type: Technical upgrade. Location: Within the existing TPU production facility in Wanhua Yantai Industrial Park, Yantai Chemical Industry Park. Total investment: 23.34 million yuan. Scope of construction: Adaptation of the raw material supply units for production lines No. 31–40; construction of 2 fixed-roof storage tanks with a capacity of 660 m³ each and 3 isocyanate storage tanks with a capacity of 8.7 m³ each. The extrusion reaction, underwater granulation, drying, and homogenization/packaging units associated with these production lines will not be modified, and the production capacity of these lines will remain unchanged. After the technical upgrades, the product lineup has changed from 33,000 tons per year of MDI-type TPU to 8,200 tons per year of regular MDI-type TPU, along with 25,000 tons per year of high-end TPU made from special isocyanates.
Project 2: Project Name – 40,000 tons per year polyether amine production project. Project Type: New construction. Location: Wanhua Yantai Industrial Park, Yantai Chemical Industry Park. Total investment: 296.96 million yuan. Construction details: A new production facility with an annual capacity of 40,000 tons of polyether amine will be built; in addition, one polyether pipeline (350 meters long, running from the Class C tank area to this facility), one liquid ammonia pipeline (50 meters long, running from the methylamine facility to this facility), and two polyether amine pipelines (350 meters long each, running from this facility to the Class C tank area) will be constructed； Pipelines such as one from the Class C tank area to the packaging room (150 m in length), one high-pressure ammonia-containing exhaust pipeline (from this unit to the methylamine unit, 100 m in length), and one wastewater pipeline (from this unit to the Fenton treatment unit in the eastern area, 3500 m in length); in addition, a new initial rainwater pond with a capacity of 20 m³ will be constructed. Other utility systems, storage and transportation facilities, and auxiliary installations all rely on existing projects.
Project 3: Project Name – 60,000 tons per year polyester polyol production project. Project Type: Expansion. Location: Wanhua Yantai Industrial Park, Yantai Chemical Industry Park. Total investment: 203,877,100 yuan. Construction scope: Construction of a new polyester polyol production facility with an annual capacity of 60,000 tons, including 5 production lines equipped with 100 m³ reactors and 1 production line equipped with a 50 m³ reactor； One solid feeding system (including a set of bag filters) and one filling system will be added at the far westernmost part of raw material warehouse B. Facilities such as accident ponds, rainwater collection ponds, and temporary storage for solid waste all rely on existing projects. Upon completion of the project, it will be possible to produce an additional 60,000 tons per year of polyester polyol products, corresponding to 30,000 tons per year of WHP-320, 20,000 tons per year of WHP-321, and 10,000 tons per year of WHP-322.
Project 4: Project Name – Nutritional Products Project; Project Type: New Construction; Location: East Area of Wanhua Yantai Industrial Park, Yantai Chemical Industry Park; Total Investment: 1,489.2 million yuan; Construction Scope: The project involves the construction of 3 production units, including an FCA (pentanal) unit, VBL (viol) and FVA (W ester) units, and an RDP unit； Construct supporting auxiliary projects, which specifically include the nutrient products storage tank area, the storage and transportation tank area in the eastern zone, the loading and unloading station in the eastern zone, and the 18th circulating water station, among others. Product plan: 94.2 tons/year of FCA (pentanal), 5,400 tons/year of PON (pseudoindigo), 2,990.9 tons/year of TPPO (triphenylphosphine oxide), 2,468.86 tons/year of C15 phosphonate, 700 tons/year of W ester concentrate, 392 tons/year of W ester crystals, 10,003.8 tons/year of W ester formulations (including 3.6 tons/year of substandard products), and 9,635 tons/year of by-product **furan (THF).

Pentose aldehyde, also known as DL-xylose or α-D-xylose, is an important chemical raw material that is used as a calorie-free sweetener in foods and beverages, suitable for people with obesity and diabetes. Industrially, xylose is primarily used to produce xylitol through hydrogenation. Xylose has a wide range of applications in fields such as food, pharmaceuticals, chemicals, leather, and dyes.
