150000 tons of EVA device landed in Jingbian, Yu can chemical polyethylene production capacity will reach 538500 tons.

on August 27, Yulin Municipal Bureau of Ecological Environment made a public announcement on the acceptance of the environmental impact report of the 150000-ton/year kettle-type EVA plant project of Shaanxi Yulin Coal Yulin Energy and Chemical Co., Ltd.

Shaanxi Yanchang China Coal Yulin Energy and Chemical Co., Ltd. (hereinafter referred to as "Yu Nenghua") plans to invest in the construction of a 150000-ton/year kettle-type EVA plant project in the reserved space in Jingbian's existing factory area, with a total investment of 3,080.896 million yuan. This major investment decision reflects the company's strategic layout in the field of high-end chemical products.

The project adopts advanced autoclave process technology and has flexible production capacity for multiple products. It can flexibly produce EVA (ethylene-vinyl acetate copolymer), EnBA (ethylene-butyl acrylate copolymer), EMAA (ethylene-methacrylic acid copolymer) and LDPE (low density polyethylene) according to market demand. The production capacity of single products is not more than 150000 tons/year, and the total production capacity is designed to be 150000 tons/year. This flexible production mode fully embodies the intelligent production concept of modern chemical enterprises to deal with market fluctuations.

existing capacity base and market position

at present, Yuneng has a capacity of 300000 tons/year of LDPE/EVA plant, which has a significant competitive advantage in the domestic market. Through years of technology accumulation and market development, the company has established a solid market position in the field of polyethylene products. The decision to expand production is based on a comprehensive assessment of the current production situation, market supply and demand and economic benefits, and aims to further enhance the price discourse power and market share of products in the market.

raw material supply guarantee system

the biggest highlight of the project is its perfect raw material supply guarantee system. The efficient integration of internal raw materials is achieved by optimizing the load configuration of existing units:

unit load adjustment strategy: the company adopts accurate load reduction operation mode for the existing three sets of units, of which the load of LLDPE unit is adjusted to 89.5, the load of HDPE unit is adjusted to 90%, and the load of LDPE/EVA unit is adjusted to 90%. through this optimized configuration, 82800 tons/year of raw material ethylene can be provided.

Product structure adjustment: The existing polypropylene PP3 plant is fully shifted to the production of homopolymeric products from propylene raw materials, which no longer consumes ethylene resources, thus providing an additional 26500 tons/year of raw material ethylene for the new plant.

Through the above-mentioned internal resource integration, the project can obtain a total of 109300 tons/year of raw material ethylene, which fully meets the production demand of 150000 tons/year EVA unit (105700 tons/year). This integrated raw material supply model not only reduces the cost of raw material procurement, but also ensures the continuity and stability of production.

supporting infrastructure

the project covers a complete system of production and auxiliary facilities, including packaging plant, circulating water yard, ground flare, peroxide depot and 2. # main substation, tank farm and central control room renovation and other public and auxiliary facilities. The investment in environmental protection is 6.22 million yuan, accounting for 0.2 of the total investment of the project, reflecting the importance of enterprises to environmental protection requirements.

Technology Advantage

the project adopts autoclave process technology and integrates tubular tail technology, which is an advanced combination in China. The kettle process has the characteristics of stable product quality and strong production flexibility, which is especially suitable for the production needs of multi-species and differentiated products.

capacity scale effect

after the completion of the project, Yu nenghua's polyethylene production scale will reach 538500 tons/year (including 268500 tons/year LLDPE and 270000 tons/year HDPE), adding 150000 tons/year EVA/EnBA/EMAA/LDPE production capacity. This capacity scale will enable the company to occupy a more important position in the northwest polyethylene market.

industry chain synergy effect

the project makes full use of the company's upstream and downstream integration advantages and resource optimization allocation capabilities, and achieves the dual goals of cost control and supply chain stability through the establishment of an internal raw material supply system. This industry chain synergy will significantly improve product competitiveness and gain a greater advantage for the company in the fierce market competition.

the leading role of regional economy

as a major chemical project located in Shaanxi's Jingbian Economic and Technological Development Zone, the construction of the unit will inject new vitality into local economic development. The project can not only promote the development of related industrial chains, but also create local employment opportunities and promote the optimization and upgrading of regional industrial structure.

from a market perspective, EVA, as an important chemical intermediate and functional material, continues to grow in demand in areas such as photovoltaics, packaging, shoe materials, wires and cables. Especially with the promotion of the national "double carbon" goal, the demand for EVA in the photovoltaic industry will maintain a strong growth momentum.

Through multi-product flexible production design, the project can adjust the product structure in time according to market changes and effectively avoid the market risk of a single product. At the same time, relying on the existing production capacity base and perfect sales network, the new capacity is expected to quickly achieve marketization.
