On the afternoon of March 11, 2025, Ju Lirang, the Chairman of Henan Jiuye Chemical Equipment Co., Ltd., a well-known domestic evaporator manufacturing enterprise, led Dong, the Executive Vice President, and Dai, the Vice President, to visit Xiamen Tungsten Co., Ltd. (hereinafter referred to as "Xiamen Tungsten") and the Xiamen Tungsten New Energy Factory for exchanges and learning. This trip focused on the application and innovation of evaporator technology in the evaporation and concentration process during APT production and in the field of new energy materials. The aim is to promote the coordinated development of the upstream and downstream of the industrial chain, explore new paths for energy conservation and consumption reduction, and contribute to the realization of the "dual carbon" goal.  

01: Entering Xiamen Tungsten Co., Ltd. to jointly explore new processes for energy conservation and consumption reduction in the production process of ammonium paratungstate (APT)

The first stop of the exchange delegation was Xiamen Tungsten Co., Ltd. Accompanied by Mr. Hu, the Deputy General Manager of Xiamen Tungsten's Jialu and Haicang branches, the delegation visited the ammonium paratungstate (APT) evaporation and crystallization production line and the intelligent control center. As a leading global enterprise in tungsten products, Xiamen Tungsten has strict requirements for the stability, energy efficiency, and environmental protection performance of evaporation equipment during the APT production process. The two sides carried out technical discussions on topics such as "optimization of the evaporation process" and "recovery and utilization of waste heat". Chairman Ju Lirang said, "The high-efficiency multi-effect evaporation system and MVR falling-film evaporator independently developed by our company can precisely match the APT production scenarios. Through intelligent control, the energy consumption can be reduced by more than 30%. We look forward to jointly building a demonstration project with Xiamen Tungsten."

02: Visiting the New Energy Materials Base and Discussing the Resource Utilization of Ammonium Chloride Together

At Xiamen Tungsten New Energy Factory, a leading enterprise in the field of new energy materials, the exchange delegation focused on learning about the recycling and treatment process of ammonium chloride (NH?Cl) by-products. Engineer Li from the new energy factory introduced that with the rapid development of the lithium battery industry, the efficient separation and recycling of ammonium chloride have become the key to reducing costs and increasing efficiency. The team from Henan Jiuye Chemical Equipment Co., Ltd. demonstrated a modular MVR evaporation and concentration solution on-site. This technology can increase the treatment efficiency of ammonium chloride solutions by 30% and achieve near-zero wastewater discharge. The two sides reached a preliminary intention to jointly develop customized evaporation-crystallization combined production equipment to promote the upgrading of green manufacturing of new energy materials.  

03: Anchor on Technological Innovation and Jointly Draw a Blueprint for Cooperation

At the symposium, the person in charge of Xiamen Tungsten Co., Ltd. and Xiamen Tungsten New Energy Factory highly recognized the technical accumulation of Henan Jiuye Chemical Equipment Co., Ltd. in the field of evaporation. The three parties discussed topics such as "joint research and development of process equipment" and "energy conservation and consumption reduction during the evaporation process of APT production". Chairman Ju Lirang emphasized, "As a full-chain service provider of evaporation systems, we will continuously focus on the pain points of our customers and create incremental value for our partners through process innovation." At the end of the meeting, all parties agreed to establish a special working group to accelerate the technical docking and the implementation of projects.

This exchange and learning activity marks that the cooperation among Henan Jiuye Chemical Equipment Co., Ltd., Xiamen Tungsten Co., Ltd., and Xiamen Tungsten New Energy Factory has entered a new stage. In the future, the three parties will rely on their respective technical advantages to deepen coordination in areas such as energy conservation and consumption reduction in APT production and the circular economy of new energy materials. They will use intelligent and green solutions to empower the high-quality development of the industry.
