Clicks: 108. Recently, the C3 separation tower for Tianjin Bohua Chemical Development Co., Ltd.’s “two-industry” relocation and renovation project, which was contracted by Tianchen Company, was successfully hoisted into place. The Bohua project is a key initiative for Tianchen Company to implement refined management. Among them, the lifting of the C3 separation tower is of paramount importance among the large-scale lifting tasks for the Bohua PP project. The overall height of the C3 separation tower is nearly 80 m, and its weight is nearly 150 t. Following thorough preliminary preparations, the installation of pipeline systems attached to the tower, ladder platforms, anti-corrosion and insulation measures, electrical supports, and pipelines was completed. The \"Two-Innovation\" relocation and transformation project of Tianjin Bohua Chemical Development Co., Ltd. involves the construction of 2×1800,000 tons/year methanol-to-olefins (MTO) plants, 300,000 tons/year polyethylene (PE) plants, 2×300,000 tons/year polypropylene (PP) plants, 600,000 tons/year ion-exchange membrane caustic soda plants, 800,000 tons/year polyvinyl chloride (PVC) plants, 60,000 tons/year ethylene oxide (EO) plants, 40,000 tons/year surfactants (EO, AEO) and water reducers (PEG) plants, a 200,000 tons/year propylene oxide plant coupled with a 450,000 tons/year styrene plant (PO/SM), 100,000 tons/year polyether PPG plants, 30,000 tons/year polymer polyols (POP) plants, and 100,000 tons/year hydrogen peroxide plants. Among them, the 1.8 million tons per year methanol-to-olefins project utilizes the DMTO-Ⅱ methanol-to-olefins proprietary technology of Xinxing New Energy Technology Co., Ltd. http://img.yf116.cn/image/img/20191203/2116357659552.jpg The “integration of industry and information technology” relocation and transformation project of Tianjin Bohua Chemical Development Co., Ltd. is located to the south of Xigangchi in the Nangang Industrial Zone of Tianjin Economic-Technological Development Area, and to the east of Nangang Sixth Street. With Tianjin Dagu Chemical Co., Ltd. and Tianjin Botian Chemical Co., Ltd. as the main entities involved, the project relies on olefin production facilities and caustic soda production facilities as its core industrial components. Based on the principle of chlorine balance, and taking into account the existing technologies and scale of the old factories, as well as factors such as raw material sources, surrounding product markets, and the company’s current product portfolio, downstream industries have been developed successively to extend the product chain. In August 2016, Pan-Pacific Energy Company, a wholly-owned subsidiary of Shanghai BIKO Clean Energy Technology Co., Ltd., and Bohua (**) Co., Ltd., a wholly-owned subsidiary of Tianjin Bohai Chemical Group Corporation, officially signed a methanol purchase agreement with an annual capacity of 1.8 million tons in Tianjin. The agreement will meet the long-term demand for methanol feedstock in Bohai Chemical’s new methanol-to-olefins plant, and it will utilize the inexpensive natural gas resources in North America to produce methanol, thereby supporting the development of methanol-to-olefins and other downstream methanol industries along China’s coast.
