Ten years of rapid development in chemical technology – praise for China’s prosperity and strength. This is just a starting point; more participation from everyone will make things even more lively. Haichuan becomes even better with you here; we welcome everyone to join in the forum discussions. The fragrance of rice flowers in August ----------------------------------------- On August 1, 2023, Yulin Refinery, together with Workshop 3, managed to localize the K304 booster fan, a key imported component of the 1 million tons per year continuous reforming unit’s regeneration system, and completed its installation on-site. 　　The original fan was manufactured by a foreign company; since the continuous reforming unit came online in 2015, this fan has been in operation with regular maintenance, and all spare parts required for its repair must be imported. The full localization of these fans is expected to break the complete reliance on foreign technology for key equipment in the regeneration system, enabling the use of domestically produced equipment as a replacement for the first three imported fans in this system. This will not only accelerate the process of localizing such equipment but also lead to significant cost savings and improved efficiency, with an estimated cost reduction of 50%. 　　This domestically produced fan is the key power device that enables continuous flow in the catalyst regeneration system; it is a device requiring high levels of technical precision and operating at high speeds. Its manufacturing process is lengthy, and its design and production are challenging, which is why imported products are generally used for similar systems in China. Based on thorough market research, on-site inspections, technical evaluations, on-site measurements, data collection, and specialized studies, Yulin Refinery formulated its recommendations regarding the use of domestic fans. Through a bidding process, leading domestic equipment manufacturers were assigned the task of designing and producing these fans. 　　At present, the main unit of the fan has been installed, the foundation grouting work is complete, the electrical and instrumentation wiring has been finished 100% on site, and the fan interlock configuration is under debugging. Once the fan is put into use, it can increase the safety factor of the regeneration system’s operation; meanwhile, the use of domestic spare parts is expected to significantly reduce the operating costs of the equipment.
