I. Insights from the Parade: The “Self-Supporting and Controllable” Foundation of a Major Country’s Innovation

The grand military parade at Tiananmen Square on September 3 presented a stunning feast of equipment, sounding a powerful clarion call for China's innovation. The new-type aircraft carriers, stealth fighters, strategic missiles and other domestic active-duty main battle equipment on parade not only demonstrated the leapfrog upgrading in the national defense field, but also, with their "fully self-supporting and controllable" hardcore strength, proved China's innovation confidence in moving from "following" and "keeping pace" to "leading".

From the micron-level precision manufacturing of core components to breakthroughs in the collaborative integration of equipment systems, every detail interprets the strategic resolve of "grasping key technologies in our own hands" and sets a benchmark of "striving for excellence and pursuing independent innovation" for all industries. In the industrial sector, Henan Jiuye Chemical deeply engages in the evaporation and crystallization track, and responds to the mission of a major country with its continuously iterated core technologies, becoming a vivid microcosm of "Made in China" advancing toward high-quality development.

II. Looking Back at 2012: Seven-Effect Technology Reshapes the Industry Landscape and Builds a Strong Reputation for China's Evaporation Sector

Back in 2012, with its pioneering innovative courage, Henan Jiuye Chemical launched the world's first seven-effect evaporator technology, reshaping the technological landscape of the alumina production field in one fell swoop. At that time, traditional evaporation equipment generally faced bottlenecks of low energy efficiency and high energy consumption, while the monopoly of foreign technologies in turn led to persistently high costs for enterprises' upgrading.

Jiuye's breakthrough in seven-effect technology not only broke this deadlock, but also helped the industry reduce costs and improve efficiency with a revolutionary energy-saving solution — this marked the first time that China's evaporation technology stood at the forefront of the world, and also laid a solid foundation for subsequent technological iterations.

III. Iterative Upgrading: The "Hardcore" Technological Restructuring of the Eight-Effect Evaporator

Today, Henan Jiuye Chemical continues to write a brilliant chapter — it has not only successfully developed the world's first eight-effect evaporator, but also formally signed a contract for the Indonesia Alumina Project, and is about to bring this "Created in China" achievement to the global market. From "seven-effect" to "eight-effect", while it may seem like a simple progression in numbers, it is actually an in-depth restructuring of evaporation technology:

In terms of material selection, it broke through the bottleneck in corrosion and wear resistance, solved the problems of fouling and corrosion under special working conditions, and greatly extended the service life of the equipment. In process design, it optimized the path of cascaded steam utilization, raising the recovery efficiency of secondary steam to a new level. During system integration, it was equipped with an intelligent control system that can match working condition parameters in real time, ensuring stable and efficient operation of the equipment under different loads. Every upgrade embodies the ingenuity of the R&D team and also marks that China's evaporation equipment technology has entered the global leading ranks.

IV. Three Core Technological Advantages: Defining New Heights for Global Evaporation Equipment

Under the dual driving forces of the Belt and Road Initiative and the global demand for green development, this world's first-launched eight-effect evaporator is redefining the performance standards of global evaporation equipment with two core technological advantages:

1. More Efficient Heat Energy Utilization: Break Through the Bottleneck of Steam-Water Ratio and Materialize Energy-Saving Benefits

   Relying on multi-dimensional cascaded heat exchange technology, it accurately converts the secondary steam generated by the previous effect into the heating source for the next effect, realizing the "cascaded relay" of steam energy. Compared with the seven-effect evaporator, the eight-effect equipment reduces the steam-water ratio by approximately 0.03 by adding one additional effect — this seemingly minor numerical optimization delivers remarkable results in actual production.

   Take an alumina plant with an annual output of 2 million tons as an example: when equipped with two sets of 450t/h eight-effect evaporators, its annual steam savings can reach 227,000 tons. Calculated at the domestic steam price of 100 yuan per ton, its annual steam cost savings amount to as much as 22.7 million yuan. Even in overseas regions such as Indonesia, since local coal prices are similar to those in China, the energy-saving benefits for projects of the same scale remain valid, alleviating the pressure of operating costs for enterprises at the source.

2. More Prominent Green Attributes: Full-Cycle Carbon Reduction, Aligning with the Global "Dual Carbon Goals"

   The "green genes" of the eight-effect evaporator are reflected in its full life cycle: First, the reduction in steam consumption directly reduces the combustion volume of coal and other fuels, thereby indirectly reducing the emissions of pollutants such as sulfur dioxide and nitrogen oxides; Second, the main body of the equipment adopts recyclable corrosion-resistant alloy materials, which reduces resource waste; Third, combined with process improvement, it further reduces wastewater discharge during the production process.

   Data shows that this equipment can enable a reduction in the unit cost of alumina by 11 yuan per ton, with annual energy-saving benefits amounting to 21.95 million yuan — it not only helps enterprises achieve the dual goals of "cost reduction + carbon reduction" but also provides a replicable "China's solution" for the global industrial green transformation.

   V. From "Products" to "Standards": China's Technology Empowers Global Industries

   From the seven-effect technology breaking into the market in 2012 to today's eight-effect equipment embarking on overseas export, Jiuye Chemical's development path is a microcosm of "Made in China" upgrading from "product export" to "technology export" and "standard export".

   The overseas launch of the eight-effect evaporator this time is not only a technological implementation, but also means that the design standards, engineering specifications and green concepts of China's evaporation equipment will be deeply integrated into the industrial development along the Belt and Road Initiative. When the eight-effect evaporator is put into operation overseas, it will bring not only tangible economic benefits, but also enable the world to see the reliability and advancement of "China's technology", paving the way for more Chinese industrial technologies to go global.

   VI. Conclusion: Taking Innovation as the Pen, Writing a New Chapter of "Created in China"

   When the "China Speed" at the military parade stirs people's hearts, and "Great Power Innovation" becomes the main theme of the times, Henan Jiuye Chemical, through the overseas launch of its eight-effect evaporator, has written a vivid footnote to "Made in China + China's Solution".

   From the independent and controllable nature of national defense equipment to the technological leadership of industrial equipment, the story of China's innovation has never been a coincidence of isolated breakthroughs, but an inevitability driven by countless enterprises like Henan Jiuye Chemical—enterprises that dedicate themselves to intensive cultivation and persist in overcoming challenges in their respective fields. In the future, with the widespread application of the eight-effect evaporator overseas, we will witness "China's Technology" injecting green impetus into the global alumina industry; on a broader track, we also look forward to more Chinese enterprises taking innovation as their pen to paint a splendid picture of "Created in China" on the world stage, allowing the confidence derived from independent innovation to become an important force driving the progress of global industries.
