Total investment 10.3 billion, Shaanxi Yuneng 10 billion chemical project to meet the key node.

On November 3, 2025, Shaanxi Yuneng Fine Chemical Materials Co., Ltd. made key progress in the 1 million-ton/year high-end chemical new material project-the first epoxidation reactor of the 100000-ton/year propylene oxide plant was successfully installed. The equipment is the core reaction unit of the propylene oxide production line, and its smooth placement marks that this large chemical complex with a total investment of 10.3 billion yuan has officially entered the stage of equipment installation and implementation.

Core equipment technical parameters: the epoxidation reactor has a net weight of 260 tons, a diameter of 3.5 meters and a total height of 24.73 meters. It is a large-scale special chemical equipment. The installation operation is carried out by the Northwest Branch of 16th Chemical Construction Company. The two-machine coordination scheme of 650-ton crawler crane main crane and 260-ton crawler crane sliding tail is adopted to ensure the safety and accuracy of hoisting operation. On November 2, three reactors arrived at the site on schedule, and the seamless connection between the equipment supply chain and on-site construction reflected the efficiency of project management.

Project scale and industrial chain layout

basic information: the project is located in the southern area of Qingshui Industrial Zone, Yushen Industrial Park, Yulin City, covering an area of 1500 mu (about 100 hectares). The overall design budget investment is 10.3 billion yuan (about 1.43 billion US dollars). It is positioned as a key chemical new material industry base in Shaanxi Province. The annual comprehensive energy consumption equivalent of the project is 269000 tons of standard coal, which is in line with the energy consumption characteristics of a large petrochemical complex.

industry chain architecture analysis: the project has built a vertically integrated chemical new material industry cluster, covering nine major production devices and supporting public and auxiliary systems, forming a complete value chain:

basic chemical layer:200000 tons/year ethylene oxide (EO) plant, 100000 tons/year propylene oxide (PO) plant and 260000 tons/year hydrogen peroxide plant provide key raw materials and oxidants. Ethylene oxide and propylene oxide are important C2 and C3 epoxy compounds, which are widely used in surfactants, polyethers, solvents and other downstream products.

Intermediate and functional material layer:400000 tons/year DMTA (dimethyl methacrylate ether) device, 200000 tons/year polyether water reducer macromonomer device, focusing on the field of building materials additives. DMTA is the core monomer of polycarboxylate superplasticizer, which realizes the industrial chain extension from basic epoxy compound to functional monomer.

acrylic acid value chain:80000 tons/year acrylic acid, 120000 tons/year butyl acrylate, 400000 tons/year acrylate emulsion device, to build a complete industrial chain from acrylic monomer to esterification products to polymer emulsion, product application covering coatings, adhesives, textile additives and other fields.

End Application Product Layer:400000 tons/year polycarboxylate superplasticizer device, directly facing the concrete admixture market. The device comprises two subsystems: a mother liquor synthesis unit (1190) and a compounding production unit (1191). The mother liquor synthesis unit has 4 production lines with an annual production capacity of 275000 tons, of which 75000 tons are supplied to internal compounding devices and 200000 tons are sold as chemical intermediates. The compound device produces 200000 tons of finished water reducing agent annually, and the product performance can be customized according to customer needs. This business model of "vertical integration and flexible export" not only ensures the stability of the industrial chain, but also obtains market premium through intermediate trade.

market positioning and strategic value: polycarboxylate water reducing agent (PCE) is the third generation of high-performance concrete admixture, compared with the traditional naphthalene and aliphatic water reducing agent, with lower doping, higher water reduction rate and better environmental performance, is the mainstream direction of the global concrete technology upgrade. After the project is put into operation, it will become the largest production base of polycarboxylate superplasticizer in Northwest China, significantly enhancing the supply chain security of regional building materials chemical industry. For overseas traders, the project will change the supply and demand pattern of epoxy compounds, acrylic acid and their derivatives in western China, and may affect the regional price system and trade flow of related products. The integrated configuration of the project helps to reduce production costs and enhance the competitiveness of Chinese products in the international market.
