In the surging wave of the aluminum industry's transformation, at the 12th Aluminum Industry Science and Technology Conference, Henan Jiuye Chemical Equipment Co., Ltd. made a powerful breakthrough with the globally(first-of-its-kind globally) eighth-effect evaporator! Ju Lirang, the Chairman and Senior Engineer, released the report titled "Practice and Exploration of New Energy-saving Technologies in the Evaporation Section of Green Alumina Production", injecting a shot in the arm into the industry during the downturn with disruptive technologies.
As the "ultimate weapon" for the evaporation of low-concentration alumina mother liquor, the eighth-effect evaporator, with core technological innovations such as optimized temperature difference distribution and precise heat balance calculation, achieves the same temperature difference as the seventh-effect evaporator under high-concentration conditions in low-concentration working conditions, ensuring stable operation with zero risk. The thermal balance data verifies its powerful efficiency: compared with the seventh-effect evaporator group, the steam-water ratio drops directly by 0.03. Calculated based on an alumina plant with an annual output of 1.2 million tons, it can save 150,000 tons of steam annually. According to the domestic steam price of 1,800 yuan per ton, it can save 27 million yuan in costs per year; in regions where the steam price exceeds 300 yuan per ton, the annual cost savings soar to 45 million yuan!
Although the renovation investment is approximately 25 million yuan more than that of the seventh-effect evaporator, the payback period is less than seven months (excluding government subsidies). With the protection of multiple patented technologies, it truly achieves "short-term investment and long-term returns." During the critical period when the alumina price is under pressure, the eighth-effect evaporator of Jiuye, with its superior advantages in extreme energy conservation and cost reduction, redefines the industry standards. It is bound to cause a strong stir in the global market and lead the green intelligent manufacturing of the aluminum industry into a new era!
