Four National Chemical Industry Chains! Strengthening The Bones Of Green Chemical Development

The by-product salt produced by Lingang Chemical's trimer hydrogen chloride project is recycled as raw material for the ion membrane caustic soda project; the waste hydrogen chloride produced by Cangzhou Dahua is provided to Jinniu Chemical to work as raw material for PVC production ...... In Bohai New Area, through the linkage within and between enterprises and between upstream and downstream, a lip-to-tooth, mutually The industry chains that power each other bring strong impetus to economic development.

In the Bohai New Area, there is a very "delicate" principle for setting up projects: all projects that can form a circular industrial chain are given priority to be approved and run in the area; enterprises that can form a circular industrial chain are placed in the same planning area.

Under the guidance of this principle, Bohai New Area has further optimized the allocation of industrial resources, rationalized the upstream and downstream relationship of related products, and built up a preliminary structure based on petrochemical, coal chemical and salt chemical industries, with "olefin industry chain, aromatic hydrocarbon industry chain, thick The green chemical industry system is led by the petrochemical, coal chemical and salt chemical industries, led by the "olefin industry chain, aromatic hydrocarbon industry chain, concentrated seawater comprehensive utilization industry chain and energy clean and efficient utilization industry chain", and supported by several branch chains, so as to realize the reduction and reuse of resources.

The "trienes" (ethylene, propylene and butene) in the olefin industry chain are important chemical raw materials in China, especially ethylene and propylene, which are the two most widely used raw materials and are mainly used in high-end synthetic resins, special fibres, special rubber, biopharmaceuticals, high-end special chemicals and special chemicals.

Around the "trienes" raw materials, Bohai New Area has also built "ethylene - vinyl chloride - polyvinyl chloride - pipes, profiles, films" "Propylene - polypropylene - cast film - protective clothing, masks" and other small industrial chains, built Hebei Baosheng annual output of 150,000 tons of polystyrene, Wuzhou Kaiyuan annual output of 10 million cubic meters of insulation materials, BDF annual output of The company has completed a number of projects, including 150,000 tons of polystyrene per year in Hebei Baosheng, 10 million cubic meters of insulation materials per year in Wuzhou Kaiyuan, 200,000 tons of acrylic emulsion per year in Badrich, 300,000 tons of polypropylene per year in Lihe Zhixin, 15,000 tons of PE permeable cast film per year in Hyde Plastic, and 370 million masks per year.

Among them, the Lihe Zhixin high-performance resin project is a key node project in the olefin industry chain, which can digest the ethylene and propylene by-products of Xinhai Chemical and other existing enterprises in the park locally, further extend them to new materials and optimize and enhance the structure of the existing petrochemical industry.

The project adopts advanced production technology and recycles all the emitted gases through advanced variable pressure adsorption technology, basically achieving "zero emission" of waste gases.

At the same time, the project's products are widely used in packaging, automobiles and home appliances, which will effectively alleviate the reliance on imported products.

The "tritylene" (benzene, toluene and xylene) in the aromatic hydrocarbon industry chain is an important chemical raw material for engineering plastics, synthetic fibres, dyes, paints, pesticides and fragrances, etc.

At present, there are CNOOC Zhongjie Petrochemical, Xinhai Chemical and Hebei Xinqiyuan producing "tritylene" in Bohai New Area. "The product line of "toluene - TDI - polyurethane resin - polyurethane foam - car seats, mattresses, paving materials" has been formed. "benzene-aniline - diphenylmethane diisocyanate (MDI) - insulation materials, paving materials" and other small industrial chains have been built, and Cangzhou Dahua with an annual output of 150,000 tons of TDI, Cangzhou Junchi Weiye polyurethane integration, Huateng Wan Fuda with an annual output of 4,000 tons of polyurethane adhesives and other projects.

Relying on rich salt resources, Bohai New Area has further developed seawater desalination and comprehensive utilization of concentrated brine industries, gathering key enterprises such as Cangzhou Salt Industry Group, Hebei Lingang Chemical Industry, Cangdong Power Plant, etc.

The existing raw salt production capacity is 1 million tons, and projects such as 82,500 tons of seawater desalination per day, 460,000 tons of ion membrane caustic soda per year, 2,000 tons of bromine per year of Cangzhou Salt, and Canghai Cultural Scenic Area have been built.

In the energy clean and efficient utilization industry chain, the green energy industry, such as coal hydrogen production and comprehensive utilization of hydrogen energy, has gathered such enterprises as Zhengyuan Hydrogen Energy, Xinguo Hydrogen Energy and Zhongxiang Energy, and built such projects as hydrogen production, hydrogen purification and natural gas.

The industry chain of "hydrogen production - midstream purification, hydrogen storage - downstream application (chemical hydrogenation, hydrogen battery, hydrogen car, hydrogen station)" has been built, and the project of clean and efficient comprehensive utilization of hydrogen coal is being accelerated.

In view of the high technical content of chemical products and the increase in production costs for enterprises to conduct pilot tests in the field for new product research and development, Bohai New Area supports key enterprises in the park to establish pilot bases and organizes technical exchanges between enterprises to realize the circulation of scientific research and technical elements among enterprises.

At the same time, we pay close attention to environmental protection governance and strive to harmoniously adapt to the development of the industrial chain. We also provide guarantees for achieving high-quality economic development by establishing mechanisms such as policy incentives and reserving skills for technical reform projects.
