In the long journey of alumina production, the issue of energy consumption is like the Sword of Damocles hanging high, restricting the development of the industry. The eight-effect evaporator developed by Henan Jiuye Chemical Equipment Co., Ltd. is like a shining star, illuminating the path of energy conservation and consumption reduction in the alumina industry and opening up a new era of industry development!

As a leading enterprise in the field of evaporator research and development, Henan Jiuye Chemical Equipment Co., Ltd. has always adhered to the concept of innovation-driven development. After the great success of the seven-effect evaporator, the R&D team has deeply analyzed the pain points of the industry, focused on the challenges of low-concentration mother liquor evaporation, and successfully launched the eight-effect evaporator through unremitting efforts.

The technological breakthrough of the eight-effect evaporator is remarkable. The design of thermal balance and temperature difference matching is one of its core highlights. Through scientific and reasonable optimization of temperature difference distribution, the temperature difference of each effect is stably controlled within the range of 3-4¡æ, ensuring the stable operation of the system. Henan Jiuye Chemical Equipment Co., Ltd.'s rich experience in the field of high-concentration seven-effect evaporators has laid a solid foundation for the stable operation of the eight-effect evaporator under low-concentration working conditions. Verified by strict thermal balance calculations, the temperature difference of the eight-effect evaporator under low-concentration working conditions is comparable to that of the seven-effect evaporator under high-concentration working conditions. There is no risk of insufficient thermal power at all, enabling long-term and stable operation. 

In terms of key technological innovation, relying on its profound technological foundation, Henan Jiuye Chemical Equipment Co., Ltd. has made significant breakthroughs in precise thermal balance calculation and the distribution of the area of each effect. This enables the eight-effect evaporator to fully demonstrate its high-efficiency performance during the evaporation process of low-concentration mother liquor. In terms of risk prevention, the eight-effect evaporator also performs outstandingly. Drawing on the successful operation experience of the high-concentration seven-effect evaporator group, even in the face of special situations during the production process, one effect can be flexibly isolated, and the operation mode can be switched to that of the seven-effect evaporator group. Moreover, the seven-effect evaporator group after isolation operates more reliably, effectively reducing production risks.

In terms of energy-saving benefits, the eight-effect evaporator can be regarded as a "pioneer in energy conservation". Taking the 600t/h evaporator of an alumina plant with an annual output of 1.2 million tons as an example, compared with the seven-effect evaporator, the steam-water ratio of the eight-effect evaporator group can be reduced by approximately 0.03, and the annual steam savings can reach as high as 150,000 tons. Calculated at the domestic steam price of 180 yuan per ton, the annual steam cost savings can reach 27 million yuan. In regions with higher steam prices, such as Guinea, the annual steam cost savings can even exceed 45 million yuan. Such remarkable energy-saving benefits not only save a large amount of costs for enterprises but also help enterprises take solid steps in environmental protection, reduce carbon emissions, and practice the concept of green development.

The emergence of the eight-effect evaporator of Henan Jiuye Chemical Equipment Co., Ltd. has injected new vitality into the alumina industry and led the industry to forge ahead bravely towards a new era of energy conservation and consumption reduction!
