On April 25, 2025, the 13th National Technical Exchange Conference on Hydrometallurgy grandly opened in Shenzhen, Guangdong. This grand event brought together numerous authoritative experts, scholars, and business elites in the field of hydrometallurgy to jointly discuss cutting-edge industry technologies and development trends. As a leading company in the evaporator industry, the leadership team of Henan Jiuye Chemical Equipment Co., Ltd. was invited to attend, demonstrating significant influence at the conference.

During the conference, the Chairman of Henan Jiuye Chemical Equipment Co., Ltd. delivered a special report titled "Low-carbon Practices of Jiuye Chemical's New Evaporator Patent Technology in Hydrometallurgical Production: Energy Efficiency Innovation and Enhancement of Carbon Neutrality Sustainability - Applied Technological Breakthroughs for the Future of Green Metallurgy," which became the focus of the entire conference.

During the report, the Chairman of Henan Jiuye Chemical Equipment Co., Ltd. conducted an in - depth analysis of the company's arduous journey and remarkable achievements in the research and development of new evaporator patent technologies. Over the years, Jiuye Chemical has always adhered to the innovation - driven development strategy. With its profound technical foundation and continuous R & D investment, the company has successfully developed a series of energy - efficient evaporator technologies. Among them, the self - developed seven - effect two - stage separate falling - film evaporator has a leading technical level in the industry. This evaporator has not only been widely used in major domestic alumina industries but also successfully entered the international market in 2018, contributing "Chinese wisdom" to the development of the global hydrometallurgy industry.

After these advanced evaporator technologies were applied in hydrometallurgical production, remarkable positive results were achieved. Take the innovative technology of the seven - effect evaporator as an example. Its application has reduced the steam - to - water ratio of the original evaporation station from 0.3 directly to below 0.17, and the production cost per ton of alumina has been reduced by about 50 yuan. Based on the domestic alumina production of around 80 million tons last year, the steam consumption was reduced by 24 million tons, the production cost was reduced by 40 billion yuan, and the carbon emissions were reduced by 6.31 million tons.

In addition, the innovative application of evaporative condensers in alumina evaporation stations saves 3 kWh of electricity for every ton of water evaporated. Calculated based on 3 tons of water evaporation required for the production of each ton of alumina, the domestic alumina industry saves 720 million kWh of electricity annually, resulting in a cost savings of 500 million yuan and a direct reduction in carbon emissions of 484,000 tons. The cumulative reduction of 6.794 million tons of CO? by the two technologies is equivalent to the annual carbon sequestration of approximately 1.85 million hectares of forests (calculated at 3.67 tons of annual carbon sequestration per hectare) or the annual emissions reduction of 2.83 million fuel - powered vehicles (calculated at 2.4 tons of annual emissions per vehicle). These technologies have made significant contributions to the evaporator technology in the alumina industry and provided a practical technical path for the low - carbon transformation of the industry.

In the realm of low - carbon practices, Jiuye Chemical has achieved efficient heat recovery and recycling through the optimization of the evaporator system design, significantly reducing its reliance on external energy sources. The company's Chairman emphasized that Jiuye Chemical has consistently integrated the concept of green development into the entire process of technology research and development as well as product application. It is committed to providing customers with more energy - saving, environmentally friendly, efficient, and stable chemical equipment and system solutions.

The Chairman of Jiuye Chemical's excellent report at this conference comprehensively demonstrated the company's remarkable achievements in the field of evaporator technology. It also provided valuable low - carbon practice references for other enterprises in the industry, injecting strong technological impetus into promoting the green, low - carbon, and sustainable development of the hydrometallurgy industry.

Looking to the future, Henan Jiuye Chemical Equipment Co., Ltd. will take this exchange conference as a new starting point, continuously deepen technological innovation, and further strengthen exchanges and cooperation with all parties in the industry. The company will actively explore more green technologies and solutions applicable to the hydrometallurgy industry, contributing more wisdom and strength to the prosperity and development of China's non - ferrous metal hydrometallurgy industry. It will join hands with industry colleagues to jointly embrace the bright future of green metallurgy. It is believed that under the leadership of innovative enterprises like Jiuye Chemical, the hydrometallurgy industry will surely take more solid steps on the path of green development and write an even more glorious chapter.
