Recently, the evaporator renovation project of Guangxi Huayin Aluminum Co., Ltd., undertaken by Henan Jiuye Chemical Equipment Co., Ltd., has reached a major milestone — the first and second effect separation chambers of the seven-effect evaporation station have all been successfully hoisted!

Project Background: Green Upgrade of a 100-Billion-Yuan Aluminum Enterprise

Guangxi Huayin Aluminum Co., Ltd. is a backbone enterprise in Guangxi's 100-billion-yuan aluminum industry. Jointly funded by Guangxi Investment Group (34%), Minmetals Aluminum (33%), and Aluminum Corporation of China (33%), it has an annual output of 1.6 million tons of alumina and serves as a demonstration base for the ecological aluminum industry in Baise, Guangxi.

The evaporation workshop to be renovated currently has 4 sets of 220t/h six-effect three-flash evaporators, all put into operation at the end of 2007. With the increasing requirements for green and low-carbon development, Huayin Aluminum launched the "Three-Year Plan for Equipment Quality Improvement". Relying on its leading advantages in evaporation technology, Jiuye Chemical successfully won the bid for this renovation project.

Core Technology: Seven-Effect Evaporation, Leading the Industry

What Jiuye Chemical has built for Guangxi Huayin Aluminum is its patented technology — the seven-effect two-stage split-type falling film evaporator.

This technology boasts three subversive advantages:

First, it achieves an energy efficiency revolution. The technology reduces the steam-water ratio from 0.3 to below 0.17, and its heat utilization rate is 3.5 times that of traditional equipment. This improvement brings significant energy-saving benefits, with an expected annual steam saving of 12,000 tons, which is equivalent to the environmental benefit of planting 26,000 fir trees.

Second, it has the advantage of space saving. Through a three-dimensional layout design, the equipment footprint is reduced by 67%, saving valuable space resources for the plant area. The saved space is equivalent to rebuilding 1/3 of a workshop.

Third, it features intelligent control capability. Relying on the PLC system to realize real-time dynamic optimization, the control accuracy reaches ±2%, ensuring the equipment maintains stable and efficient operation even when the environment fluctuates.

Critical Moment: Precision Hoisting Demonstrates the Strength of "Jiuye Intelligent Manufacturing"

The first and second effect separation chambers hoisted this time are large-scale stainless steel equipment, with the heaviest single piece exceeding 100 tons. Facing various challenges in each hoisting operation, the Jiuye project team carefully planned and implemented with precision.

"The successful hoisting this time is not only the placement of equipment, but also a manifestation of Jiuye's full-chain service capabilities covering 'design, manufacturing, installation, and operation and maintenance'," said the project leader. "We will continue to uphold the craftsman spirit to build high-quality projects and ensure the project is put into operation as scheduled."

Green Value: A New Benchmark for Energy Conservation and Cost Reduction in the Industry

After Jiuye's seven-effect evaporation technology is put into operation in the Huayin project, it is expected to bring significant economic and environmental benefits:

? Annual steam saving of about 12,000 tons, directly reducing production costs by over 10 million yuan.

? Significant reduction in carbon emissions, equivalent to increasing the carbon sequestration capacity of 1.85 million hectares of forests in Baise every year.

? **43% saving in circulating water volume**, responding to the national water conservation call and contributing to green and sustainable development.

Jiuye's Strength: The "National Team" in the Evaporation Field

As a national high-tech enterprise and a "Specialized, Refined, Differential and Innovative" small giant enterprise in Henan Province, Jiuye Chemical has been deeply engaged in evaporation technology for 26 years, holding nearly 40 patents related to evaporators. Its leading product, the "energy-saving seven-effect two-stage falling film evaporator", has reached the world's leading technical level.

In recent years, Jiuye's products have been successfully applied in more than 30 large-scale alumina projects around the world, including:

? Guangxi Tiandong Jinxin 580t/h evaporator — the world's largest seven-effect evaporator in the alumina industry, winning the "Excellent Construction Unit" award.

? Chinalco Guangxi Huasheng 2 million-ton project — winning the "Non-Ferrous Metal Industry High-Quality Project" award.

? Oleguinea, Jiugang Jamaica, Jinjiang Indonesia and other overseas projects, demonstrating the strength of "Made in China".

Future Outlook: Jointly Creating a New Blueprint for the Green Aluminum Industry

With the successful hoisting of the first and second effect separation chambers and five sets of flash evaporators, the Guangxi Huayin project has entered the peak period of equipment installation. Jiuye Chemical will continue to uphold the concept that "low carbon is not a cost, but a competitive advantage" to ensure the smooth commissioning of the project.

By then, Guangxi Huayin Aluminum will have an industry-leading high-efficiency and energy-saving evaporation system, which will not only greatly improve production efficiency and reduce operating costs, but also set a new model for the green and low-carbon development of China's aluminum industry!
