Latest Progress on Tianjin Bohua Olefins Project Author/Source: Refining & Chemical Industry Updates Date: May 5, 2020 Clicks: 63 On April 30, the 160-metre tall, detachable main flare tower for Bohua’s relocation project carried out by Tianchen Company was successfully completed, marking the timely achievement of the first milestone in the labor competition aimed at \"fighting the pandemic, ensuring production, demonstrating responsibility, and making contributions\" within the Bohua project. It also represents another key achievement in this project, laying a solid foundation for the subsequent installation of the flare cylinder and the steady progress of the project as a whole. The main flare stack of the Bohua project consists of 3 sets of detachable flare systems, each 160 meters high; it is the tallest structure in the Bohua project as well as in the Nangang Industrial Zone. The lifting of the torch tower structure is one of the key planning tasks for the project, as well as one of the most challenging tasks in terms of construction. The tower has a total height of 150 meters and a weight of nearly 800 tons. It is lifted by methods such as direct installation on the foundation, assembly on the ground, and then lifting using a crawler crane for the main lifting operation along with another crawler crane to assist in moving it into place. As a key project under Tianjin’s 13th Five-Year Plan, the Tianjin Bohua project is being implemented against the backdrop of the coordinated development of the Beijing-Tianjin-Hebei region and the efforts to build a \"beautiful and safe Tianjin\". Taking the olefin plant and caustic soda plant as the industrial foundation (main axis), and based on the chlorine balance principle, this project develops downstream industries and extends the product chain by building upon the existing technologies and plant capacities of the old facilities, while taking into account factors such as raw material sources, sales markets for surrounding products, and the company’s current product portfolio. The relocation and transformation project for Tianjin Bohua’s industrial and chemical operations is located south of Xigangchi in the Nangang Industrial Zone of the Tianjin Economic-Technological Development Area, and east of Nangang Sixth Street. On July 18, 2018, the groundbreaking ceremony for this relocation and transformation project was held in the Tianjin Nangang Industrial Park by Tianjin Bohua Chemical Development Co., Ltd. It was approved for registration on February 3, 2016, and the environmental impact assessment was granted approval in July 2016. The total investment amounts to 29.4 billion yuan, with completion and operation expected by 2020. The project focuses on developing two main product chains: methanol-to-olefins and ethane cracking to produce ethylene, in order to create a modern, high-end industrial cluster. The project will construct 2 × 1.8 million tons per year methanol-to-olefins (MTO) plants, 300,000 tons per year polyethylene (PE) plants, 2 × 300,000 tons per year polypropylene (PP) plants, 600,000 tons per year ion-exchange membrane caustic soda plants, 800,000 tons per year polyvinyl chloride (PVC) plants, 60,000 tons per year ethylene oxide (EO) plants, 40,000 tons per year surfactants (EO, AEO) and water reducers (PEG) plants, a 200,000 tons per year propylene oxide plant with 450,000 tons per year styrene production (PO/SM) facility, 100,000 tons per year polyether PPG plants, 30,000 tons per year polymer polyols (POP) plants, and 100,000 tons per year hydrogen peroxide plants.
