Quanzhou Petrochemical 100000 Tons/Year EVA Expansion Project Core Equipment Falling

quanzhou Petrochemical 100000 Tons/Year EVA (Ethylene-Vinyl Acetate Copolymer) Expansion Project has recently completed the key engineering node-three core degassing silos are all hoisted in place. This seemingly routine construction action actually reflects the level of refinement of project management. A single silo has a diameter of 4.76 meters, a total length of 27.7 meters and a weight of 23 tons. It is a large-scale non-standard equipment in petrochemical plants. Sinochem Energy Engineering Project Center coordinates manufacturing, transportation, construction, supervision and other parties. From welding quality supervision, logistics vehicle selection to the hoisting scheme of "single host crane delivery method", the whole process control ensures safe and efficient completion of the operation on the premise of avoiding the peak period of construction, thus striving for valuable time limit advantages for the subsequent construction of the project.

Quanzhou Petrochemical EVA project adopts the ExxonMobil patented autoclave process, which has a clear differentiated positioning in the domestic market. Compared with the domestic mainstream tubular process, the kettle method has significant advantages in the production of high VA (vinyl acetate) content products. The project design can flexibly produce a full range of EVA products with VA content of 15%-40%, and focus on the layout of high VA content resin (VA≥ 33%) for photovoltaic adhesive film.

From the technical index point of view, this kind of high-end products need to meet the light transmittance ≥ 91%, anti-yellowing index ≤ 1.5, aging life of more than 25 years and other stringent requirements, is the core packaging material of the new generation of photovoltaic technology such as N-type battery, TOPCon. By optimizing the polymerization reaction temperature, pressure parameters and catalyst system, the project achieves a comprehensive energy consumption of 386.67kgce/t per unit product, which is 8% lower than the average level of similar devices in China, and the product qualification rate is stable at more than 99.5. In addition, the device also has the flexible switching capability of EVA and LDPE (low density polyethylene), which can dynamically adjust the capacity allocation according to the market price difference, which provides an important risk hedging tool for enterprises to cope with market fluctuations.

the core competitive advantage of Quanzhou Petrochemical EVA project lies in the industrial chain integration capacity of Sinochem Quanzhou 10 million tons/year oil refining and 1 million tons/year ethylene integration base. From the perspective of upstream raw material supply, ethylene is directly transported from ethylene plant to EVA plant through pipelines, reducing transportation cost by more than 90% and supply stability by 100. Vinyl acetate (VA) is stably supplied by leading domestic enterprises such as Jiangsu Huachang Chemical and Shanghai Secco through Sinochem's supply chain system, with the purity of raw materials ≥ 99.8, ensuring product batch consistency.

The cost advantage of this integrated layout is particularly critical. According to estimates, the project will control EVA production costs below 8000 yuan/ton, 5%-10% lower than the industry average. Under the background of frequent price fluctuations in the current EVA market, the cost advantage directly translates into market competitiveness and profitability stability.

The downstream market layout is also worthy of attention. Sinochem has established long-term strategic cooperation with photovoltaic enterprises in Fujian and surrounding areas, such as Follett, Haiyouwei and Saiwu Technology, and the UL-02528 grades of photovoltaic film materials produced by existing EVA devices have been verified by customers. After the expansion of the annual supply will be increased to 200000 tons, accounting for the domestic photovoltaic film market share is expected to reach 8%-10%, while expanding hot melt, cable materials, medical packaging and other high-end applications, forming a diversified product matrix.

the global energy transition accelerates the explosive growth of the photovoltaic industry. According to the International Energy Agency (IEA) forecast, the global photovoltaic installed capacity will exceed 300GW in 2025, driving the demand for photovoltaic film to exceed 2 million tons, while the domestic EVA photovoltaic capacity gap is still 300000 tons/year, the structural shortage pattern is difficult to reverse in the short term. Quanzhou Petrochemical is located in Fujian Quanzhou Quanhui Petrochemical Park, close to the Yangtze River Delta, Pearl River Delta two major photovoltaic industry clusters, products can be rapidly radiated by sea, rail national market. As the penetration rate of N-type battery technology increases (expected to reach 30% in 2025), the demand for EVA with high VA content will further surge.

However, market opportunities coexist with competitive pressures. According to incomplete statistics, the domestic plan to add more than 4 million tons of EVA capacity in 2024-2028, of which photovoltaic materials account for more than 70%, and the market will gradually shift from "structural shortage" to "total surplus". In this regard, Quanzhou Petrochemical to take a differentiated competitive strategy: on the one hand, focus on PID effect, high light transmittance and other special photovoltaic film material research and development, to fill the gap in domestic high-end products.

The environmental pressure brought by the "double carbon" policy can not be ignored. The project has built an online monitoring system for carbon emissions, and plans to introduce green electricity substitution and CCUS (carbon capture, utilization and storage) technology in the future, with the goal of reducing carbon emissions per unit product to less than 500 kgCO2/t and meeting the carbon emission standards for the petrochemical industry implemented from 2026.

quanzhou Petrochemical EVA expansion project is not an isolated capacity expansion, but an important part of Sinochem Group's strategy of "transforming from refining to chemical industry and upgrading from basic chemical industry to high-end materials. By opening up the vertical industrial chain of "crude oil-ethylene-EVA-photovoltaic materials", Sinochem will form a full chain control capability from raw materials to end products. After the project is put into operation, Quanzhou Petrochemical EVA will have a total production capacity of 240000 tons/year, ranking among the top in China. In the future, it will also plan to build POE (polyolefin elastomer), α-olefin and other supporting devices to build a new energy material industry cluster and help Fujian build a 100 billion-level petrochemical and new material industry base.

From the perspective of industry impact, the promotion of this project will alleviate the dependence of domestic high-end EVA products on imports, reduce the cost of raw materials in the photovoltaic industry chain, and enhance the global competitiveness of my country's new energy industry. At the same time, its technological innovation and green transformation practice also provide a model for the high-quality development of the petrochemical industry-while ensuring energy security, it realizes the coordinated development with the new energy industry and injects petrochemical power into the realization of the "double carbon" goal.
