Previously, we interviewed General Manager Ju of Jiuye Chemical, conducting an in-depth analysis of the technical advantages, energy-saving effects, and payback period of the world's first Eight-Effect Evaporator — a discussion that garnered widespread attention in the industry. Many readers left comments asking: After the launch of this groundbreaking technology, what has been the response in the domestic and international markets? Having previously encountered intellectual property (IP) challenges due to the imitation of its Seven-Effect Evaporator, how will Jiuye protect the technological achievements of its Eight-Effect Evaporator this time? With these questions in mind, we interviewed General Manager Ju again to bring you the latest authoritative responses

1.Explosive Response to the Eight-Effect Evaporator: More Enthusiastic Than That of the Seven-Effect (Evaporator), with Overseas Enterprises Proactively Extending Olive Branches.

When asked about the market feedback on the Eight-Effect Evaporator, General Manager Ju admitted frankly: "The response this time is more intense than when we launched the Seven-Effect Evaporator 13 years ago, and the attention it has generated in the alumina industry far exceeds expectations!" Behind this enthusiasm lies Jiuye’s confidence, which is rooted in its established reputation built on years of accumulated technological expertise.

01：Domestically: Enterprises' shift to abandoning the seven-effect (evaporator) and opting for the eight-effect (one) has become a new trend

Leveraging over a decade of stable application of its Seven-Effect Evaporator (now, newly built alumina plants have generally adopted seven-effect technology, with none opting for equipment with fewer than seven effects) and the successful cases of its Evaporative Condensers that have seen widespread adoption, Jiuye has established a benchmark for "reliable technology and energy-saving effectiveness" in the industry. Since the launch of this eight-effect technology, two coastal enterprises in China have already proactively adjusted their plans: the Seven-Effect Evaporator projects they originally planned to launch have all been switched to purchasing eight-effect equipment, showcasing their recognition through concrete actions.

02：Overseas: Regions with high energy costs have become the "core target regions"

In overseas markets where energy prices remain persistently high, the advantages of the Eight-Effect Evaporator stand out even more prominently — with the response in the Guinea market being the strongest. General Manager Ju revealed: "Guinea has high energy costs. Compared with the Seven-Effect (Evaporator), the Eight-Effect Evaporator offers a higher return on investment and achieves a more significant reduction in alumina production costs, so local enterprises have shown extremely high interest in it." Even Aluminium de France (which was once a global leader in alumina technology) — a company that exported complete sets of alumina technology to China in the early stage of China's reform and opening-up — now proactively seeks cooperation with Jiuye. For the alumina plant it is constructing in Guinea, the company has not only shown strong interest in the eight-effect technology but also invited Jiuye to customize an exclusive eight-effect solution for it. "They have to admit that we are now far ahead in the field of evaporation technology," General Manager Ju added. Furthermore, a number of enterprises in Malaysia have clearly stated that they will give priority to selecting the Eight-Effect Evaporator in the future, marking the initial success of Jiuye's overseas market expansion.

2.Learning from Past Lessons! From the "IP Compromise" of the Seven-Effect (Evaporator) to the "Strict IP Protection" of the Eight-Effect (Evaporator), Jiuye Has Strengthened Its IP Defense Line

Thirteen years ago, Jiuye pioneered the seven-effect evaporator technology globally, yet it faced difficulties in intellectual property (IP) protection due to imitation issues — even though it held patents and resorted to legal means, it still failed to protect its achievements. Speaking of this experience, General Manager Ju spoke with resolve: "When launching the eight-effect technology this time, we have learned from past lessons and made more comprehensive preparations, covering everything from patent layout to protection strategies!"

01：Full-Coverage Patents: Multiple Patents Weave a Tight Protection Network

Unlike the single-patent portfolio of the seven-effect technology, Jiuye has applied for multiple patents for the eight-effect evaporator this time, achieving comprehensive patent coverage with no blind spots across core technical principles, equipment structural design, and process optimization details. General Manager Ju emphasized: "We have proactively anticipated potential technical vulnerabilities and imitation risks, making our patent protection more multi-layered and airtight."

02.Balancing Internal and External Efforts: Riding the Momentum of Supportive Policies and Enhancing Internal Capabilities

In addition to upgrading its patent portfolio, Jiuye has also strengthened its IP protection capabilities from two aspects: On one hand, it relies on the domestic policy environment where the intensity of intellectual property (IP) protection is constantly increasing, providing more solid legal support for IP enforcement; On the other hand, it has enhanced its own patent drafting standards and litigation strategy capabilities. "In the past, we had shortcomings in patent details and IP enforcement skills. Now, through collaboration with professional teams, we can not only draft high-quality patents but also more accurately protect our rights when disputes arise," (General Manager Ju stated).

General Manager Ju stated with full confidence: "This time, we have complete assurance that we can protect the intellectual property (IP) rights of the Eight-Effect Evaporator and prevent the 'imitation dilemma' from recurring!"

Conclusion: Technology Innovation – Embarking Anew, Jiuye Leads the Alumina Industry into the Next Decade

From the Seven-Effect (Evaporator) to the Eight-Effect (Evaporator), and from a "technology follower" to a "global leader", Jiuye has proven through constant breakthroughs that only by adhering to independent R&D and strictly controlling technical quality can it gain a firm foothold in industry competition. Today, the Eight-Effect Evaporator is about to be implemented in Indonesia; domestic and overseas orders as well as cooperation intentions are constantly emerging; and its intellectual property (IP) protection system is also becoming increasingly sound.

As General Manager Ju stated, this technology is not only a new achievement of Jiuye, but also will "promote in-depth innovation in alumina evaporator technology and lead the development of the next decade". For alumina enterprises that pursue energy conservation and cost reduction and layout the global market, the Eight-Effect Evaporator may well be the "golden key" to unlocking future development.
