323 days: Fushima Company’s Phase 1 fertilizer production facility has set a new record since its commissioning in 1996

“322 days, 323 days. ”On the large screen in the main control room of Toyoshima Company’s first-phase fertilizer plant, the number of days the unit has been in operation has been updated to 323 days, a figure that breaks the historical record set by this unit since it began operations in 1996. Warm applause erupted at the scene, and the technicians wore proud smiles on their faces; at this moment, they had achieved a new milestone in terms of the long-term operation of Toyoshima Company’s first-phase fertilizer production facility. 　　Long-term operation is a highly challenging goal in the field of chemical production; especially for older plants that have been in use for over 20 years, it resembles a \"marathon\" against equipment fatigue, natural conditions, and process limitations. Within the industry, there are very few fertilizer production facilities that can operate continuously for over 300 days. Especially given the extreme climate conditions in the south, characterized by high temperatures, high humidity, and typhoons, it was considered an \"almost impossible task\" for the old production line at Tomishima to achieve such continuity in operation. 　　Difficulties have been looming from the very beginning. At the beginning of the long-term operation period, technicians observed that the efficiency of the gas turbine turbine fluctuated significantly under conditions of large day-night temperature differences. “Just as a person’s breathing speeds up and slows down, the system can also become ‘uncomfortable’. ”The technician used an analogy. Through repeated monitoring and testing, they ultimately optimized air intake distribution by adjusting the compressor inlet dampers and replacing high-performance filters, thereby significantly improving the stability of the compressor’s performance. 　　A greater challenge comes from extreme weather. As summer arrived, Typhoon Meranti struck the plant directly, and the persistent high temperatures placed significant strain on the plant’s cooling systems. The efficiency of the surface cooler in the boiler feedwater vacuum system declined significantly, nearly leading to a reduction in the plant’s capacity or even its shutdown. 　　“We barely slept those days. ”The technician in charge of solving this issue recalled, “We installed a spray water system outside the surface cooler to optimize the return path of the condensate, essentially putting a ‘cooling cap’ and ‘ventilated clothing’ on the equipment.” ”They also formulated special emergency response plans for extreme weather, successfully withstanding the severe impacts of the natural environment. 　　Technical upgrades are only the foundation; deeper support comes from the restructuring of management models. Tomishima Company implements a detailed management system for key equipment based on the principle of dividing tasks by area, position, and individual; by leveraging intelligent monitoring systems and preventive maintenance platforms, it achieves a shift from \"reactive maintenance\" to \"proactive intervention\". 　　“Each potential risk has a dedicated file, a responsible person, and a timeline for correction; after the issue is resolved, a follow-up check is required. ”Ke Zhen, the equipment technician, explained, “We now also use an intelligent management platform; employees can take photos of potential problems and upload them, and the system classifies them intelligently, which greatly improves the efficiency of handling such issues.” ” 　　The long-term stable operation of fertilizer production facilities is directly related to the availability of agricultural inputs. As an important support for agricultural production, the stability of fertilizer production is of great significance for ensuring food security. Through technological upgrades and innovation as well as intelligent management, Tomishima Corporation ensures that its older equipment continues to operate at a very high level. 　　“323 days is not an end, but a new beginning. ”Yan Junkai, general manager of the Fertilizer Department at Fudao Company, said, “We will continue to pursue technological innovation and management improvements, constantly enhancing the operational efficiency of our facilities, so as to make greater contributions to supporting agricultural production.” ”
