Recently, the cold hydrogenation pressure swing adsorption unit for the first phase of the 50,000-ton-per-year high-purity polysilicon project at Xinjiang Jingnuo New Energy—featuring process technology, engineering design, equipment procurement, construction and installation, and commissioning provided by Dakote Energy—was successfully commissioned on its first feed-in and has now passed the owner’s acceptance inspection.
This project has achieved a hydrogen purity of 99.995%, providing a new pathway and a room-temperature solution for the client to recover and utilize cold-hydrogenation tail gas through advanced technologies, thereby producing high-purity hydrogen. This supports energy conservation, emission reduction, and resource efficiency in the production of high-purity crystalline silicon, further lowering production costs.
The successful operation of this project once again demonstrates the maturity and cutting-edge nature of Dakote Energy’s technology, while also fully highlighting the company’s outstanding project management capabilities.
