The by-product salt produced by the tripolyhydrogen chloride project of Lingang Chemical is recycled as the raw material of the ionic membrane caustic soda project; the waste hydrogen chloride produced by Cangzhou Dahua is provided to Jinniu Chemical for PVC production raw materials... In Bohai New District, through The linkages within and between enterprises, as well as the linkage between upstream and downstream, and the industrial chains that depend on each other and serve as driving forces for each other, bring strong impetus to economic development.
In the Bohai New Area, there is a very "exquisite" principle for displaying projects: all projects that can form a circular industrial chain are given priority to enter the area; enterprises that can form a circular industrial chain must be placed in the same planning area. Under the guidance of this principle, the Bohai New Area further optimizes the allocation of industrial resources, straightens out the upstream and downstream relations of related products, and focuses on the requirements of "building chains, extending chains, supplementing chains, and strengthening chains", and initially builds a petrochemical and coal chemical industry. Based on the salt chemical industry, the green chemical industry system supported by several branch chains, led by the "olefin industry chain, aromatic hydrocarbon industry chain, comprehensive utilization industry chain of concentrated seawater, and clean and efficient energy utilization industry chain", has realized the reduction of resources. Quantify and reuse.
The "triene" (ethylene, propylene, butene) in the olefin industry chain is an important chemical raw material in my country, especially ethylene and propylene are the two most widely used raw materials, mainly used in high-end synthetic resins, special fibers, Specialty rubber, biomedicine, high-end specialty chemicals and specialty chemicals, etc. Around the "triene" raw material, Bohai New Area has built a number of small industrial chains such as "ethylene-vinyl chloride-polyvinyl chloride-pipes, profiles, films" and "propylene-polypropylene-cast film-protective clothing and masks" , Hebei Baosheng has an annual output of 150,000 tons of polystyrene, Wuzhou Kaiyuan has an annual output of 10 million cubic meters of insulation materials, Budfu has an annual output of 200,000 tons of acrylic emulsion, Lihe Zhixin has an annual output of 300,000 tons of polypropylene, and Haide Plastics has an annual output of 10 million cubic meters. 15,000 tons of PE breathable cast film and 370 million masks per year and other projects. Among them, the Lihe Zhixin high-performance resin project is a key node project in the upper and middle olefin industry chains. It can digest the ethylene and propylene by-products of existing enterprises in the park such as Xinhai Chemical, and further extend to new materials, optimize and upgrade the existing Petrochemical industry structure. This project adopts advanced production technology and advanced pressure swing adsorption technology to recycle all the exhaust gas, basically realizing "zero emission" of exhaust gas. At the same time, the project products are widely used in packaging, automobiles and home appliances, which will effectively alleviate the dependence on imported products.
"Triphenyl" (benzene, toluene, xylene) in the aromatics industry chain is an important chemical raw material in the fields of engineering plastics, synthetic fibers, dyes, paints, pesticides, spices, etc. Currently, Bohai New Area has CNOOC Zhongjie Petrochemical, Xinhai Chemical, Hebei Xinqiyuan and other enterprises produce "triphenyl", forming "toluene-TDI-polyurethane resin-polyurethane foam-car seats, mattresses, pavement materials" and "benzene-aniline-diphenylmethane diisocyanate (MDI)—Insulation materials, pavement materials” and other small industrial chains have built Cangzhou Dahua with an annual output of 150,000 tons of TDI, Cangzhou Junchi Weiye polyurethane integration, and Huateng Wanfuda with an annual output of 4,000 tons of polyurethane adhesives and other items.
Relying on rich salt industry resources, Bohai New Area further develops 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., with an existing raw salt production capacity of 1 million tons. Projects including seawater desalination with a daily output of 82,500 tons, ion-exchange membrane caustic soda with an annual output of 460,000 tons, bromine with an annual output of 2,000 tons in Cangyan, and Canghai Cultural Scenic Area and other projects.
In the industrial chain of clean and efficient utilization of energy, it focuses on green energy industries such as coal-to-hydrogen and comprehensive utilization of hydrogen energy. , natural gas and other projects. The industrial chain of "hydrogen production-midstream purification, hydrogen storage-downstream application (chemical hydrogenation, hydrogen batteries, hydrogen vehicles, hydrogenation stations)" has been constructed, and the project of clean and efficient comprehensive utilization of hydrogen energy coal is being accelerated.
Aiming at the problems of high technical content of chemical products and the increase in production costs of new products developed by enterprises in other places for pilot tests, the Bohai New Area supports key enterprises in the park to establish pilot test bases, and organizes technical exchanges between enterprises to realize scientific research and technology. Circulation of elements among firms. At the same time, pay close attention to environmental protection, strive to adapt harmoniously to the development of the industrial chain, and provide guarantees for the realization of high-quality economic development through the establishment of policy incentives, reserve skills and technological transformation projects and other mechanisms.
