Recently, the chlor-alkali integration unit of Phase II of Tianjin Bohua Chemical’s ‘integration of industry and informatization’ relocation and renovation project resumed operations, marking the full commencement of the project’s construction work for 2025. The relocation and transformation project of Tianjin Bohua Chemical Industry, aimed at integrating industrial and information technologies, is a key project in Tianjin, and it plays an important role in promoting the optimization and upgrading of the chemical industry as well as achieving green transformation. The cooling tower project constructed by Cangleng Company, as a key supporting facility for the chlor-alkali integrated plant, will provide efficient and reliable cooling support to ensure the safe and stable operation of the plant. To date, the key tasks for this project, including the installation of fillers in the 8 5000 m³ concrete cooling towers, the setup of the water distribution system, the installation of water collectors, the placement of wind turbines, and the installation of air ducts, have been successfully completed. The next step will be to carry out the commissioning of the turbine blades and drive shafts. This significant progress has laid a solid foundation for the overall advancement of the project, and it also creates favorable conditions for subsequent equipment debugging and trial operation. The “Two-Industry Integration” relocation and transformation project of Tianjin Bohua Chemical Development Co., Ltd. aims to build a modern, high-end petrochemical industry cluster, with a focus on developing the two main product chains of chlor-alkali chemicals and petrochemicals ； “The second phase of the \"Two Integrations\" relocation and renovation project, namely the chlor-alkali integration facility, involves using existing land resources for construction: a 300,000-ton/year caustic soda plant and a 400,000-ton/year VCM plant will be built on Plot 2; a comprehensive laboratory building will be constructed on Plot 3; and a 400,000-ton/year PVC plant will be built on Plot 4. Utility and auxiliary facilities will be installed at each plot, with a total investment of over 5 billion yuan. The project was approved for implementation in 2016; it involves the construction of a 600,000-ton/year caustic soda plant, an 800,000-ton/year vinyl chloride plant, an 800,000-ton/year polyvinyl chloride plant, a 100,000-ton/year hydrogen peroxide plant, a 300,000-ton/year polypropylene plant, a propylene oxide plant that also produces 450,000 tons/year of styrene, an 1.8 million-ton/year methanol-to-olefins plant, as well as supporting utilities, dedicated storage areas, specialized tank farms, docks, a 220KV power station, and a production management area. The total investment in the project is 29.4 billion yuan.
