Recently, the PVC project as part of Tianjin Bohua Chemical’s transformation initiative, undertaken by China Tianchen Engineering Co., Ltd., achieved three key milestones: the successful initial power connection for the 35kV and 10kV high-voltage systems in the PVC substation, the successful initial power connection for the 10kV system in the auxiliary low-voltage substation, and the successful individual testing of the circulation pump motors. These achievements mark the official entry of the project into the phase of comprehensive equipment commissioning, laying a solid foundation for subsequent testing with actual materials. Tianjin Bohua’s project for the relocation and transformation in line with the principles of industrialization and informatization is a key project in Tianjin. Once completed, it will help promote energy conservation, emission reduction, and environmental improvement, facilitate structural adjustments and transformation of the enterprise, as well as optimize the urban layout and industrial structure. During the construction process, in the face of challenges such as tight deadlines and complex concurrent tasks, Tianchen Company’s project team managed resources in a scientific manner, optimized the construction procedures, and strictly controlled safety and quality risks. They conducted multiple joint inspections with the owner and supervision unit to ensure zero errors during the power reception process ； During the commissioning of the circulating water pump, an intelligent monitoring system is used to collect data on vibration, temperature, etc., in real time, thereby accurately verifying the performance of the equipment and ensuring that it meets the required standards right from the start of commissioning. Currently, the project team is making every effort to carry out subsequent tasks such as pressure testing of process pipelines and joint debugging of the DCS system, in order to push forward toward the full delivery of the project. The “Two Industrializations” relocation and transformation project of Tianjin Bohua Chemical Industry Development Co., Ltd. aims to build a modern, high-end petrochemical industry cluster, with a focus on developing the two major 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 utility facilities, storage areas for internal use and specialized purposes, docks, 220KV power stations, and production management areas. The total investment in the project is 29.4 billion yuan.
