Recently, the alumina industry has welcomed a major milestone achievement! The "Thermal Optimization and Energy-Saving Technology and Equipment for Evaporators" developed by Zhengzhou Non-Ferrous Metals Research Institute Co., Ltd. of CHALCO has garnered intensive attention from authoritative media outlets. It has not only been featured on the front page of Science and Technology Daily, but also appeared in the special segment of Economic Information Network on CCTV-2 Finance Channel. Boasting internationally advanced technological achievements, this innovation has thoroughly addressed the long-standing industry pain point of high energy consumption in alumina evaporators, accelerating the green and low-carbon development of the aluminum industry.

Unite Aspirations, Compose Splendor Together | Juyeh Chemical’s In-Depth Participation in Benchmark Projects

Behind this landmark technological breakthrough is the joint contribution of Henan Huahui Non-Ferrous Engineering Design Co., Ltd. and Henan Juyeh Chemical Equipment Co., Ltd. As a technology-focused enterprise deeply rooted in the chemical evaporation equipment sector, Henan Juyeh Chemical Equipment Co., Ltd. has been fully engaged in the entire process—including design, procurement, manufacturing, installation and commissioning—of the evaporator projects for CHALCO Huayin, Zhongzhou and Shandong branches, which are general contracted by Henan Huahui Non-Ferrous Engineering Design Co., Ltd., a subsidiary of Zhengzhou Non-Ferrous Metals Research Institute of CHALCO. With robust equipment manufacturing strength and professional project implementation capabilities, Juyeh Chemical has served as a solid pillar for the industrial application of this energy-saving technology.

Evaporators are the core energy-consuming equipment in alumina production, accounting for 25% to 30% of the industry’s total energy consumption and nearly half of the steam consumption, making them a critical link for cost reduction and efficiency enhancement. Juyeh Chemical precisely meets the project’s technical specifications, and relying on its years of profound expertise in the R&D, manufacturing and installation of evaporation equipment, has fully ensured the efficient and steady progress of the projects, enabling "green energy-saving new momentum" to effectively empower the entire alumina production process.

Strength Ensures Progress, Ingenuity Forges Excellence | Juyeh Chemical’s Long-Term Commitment to the Evaporator Sector

This remarkable achievement in collaboration with Henan Huahui Non-Ferrous Engineering Design Co., Ltd., a subsidiary of Zhengzhou Non-Ferrous Metals Research Institute of CHALCO, is no accident. Henan Juyeh Chemical Equipment Co., Ltd. has long focused on the R&D and manufacturing of chemical evaporation equipment, with years of intensive experience in the renovation and new construction of evaporators for the alumina industry. The company holds nearly 40 national patents related to evaporators, leading the industry in core technical strength.

In 2012, the company’s independently developed patented seven-effect two-stage energy-saving evaporator technology reached international advanced levels, and this groundbreaking achievement earned it the Second Prize of Scientific and Technological Progress awarded by the China Non-Ferrous Metals Industry Association and other authoritative scientific and technological awards in 2013. In 2025, the company overcame another industry challenge and launched the world’s first patented eight-effect evaporator technology, further setting a new benchmark for evaporation energy efficiency in the industry. Its core products, including seven-effect two-stage energy-saving evaporators, falling film evaporators and eight-effect high-efficiency evaporators, have become the preferred choice for numerous alumina enterprises thanks to their advantages of low steam consumption, high efficiency, easy renovation and stable operation.

Over the years, Juyeh Chemical has always adhered to technological innovation and quality excellence, taking patented technologies as the core and scientific and technological achievements as the support. Keeping pace with the industry’s green and low-carbon transformation trend, the company fully caters to the project demands of top scientific research institutes and large-scale enterprises. Relying on the mature patents for seven-effect evaporators, cutting-edge patents for eight-effect evaporators and the technical accumulation from multiple scientific and technological awards, it provides one-stop full-chain services ranging from equipment design and manufacturing to on-site installation and operation and maintenance support.

This participation in CHALCO’s benchmark evaporator projects is not only a powerful testimony to the company’s patented technologies and project implementation capabilities, but also demonstrates Juyeh Chemical’s responsibility and commitment to helping the industry break through energy consumption bottlenecks and implement the dual carbon goals.
