Good News┃Dakote Energy Wins Bid for Shanxi Woneng’s 12,000 Nm³/h Proton Exchange Membrane Fuel Cell Hydrogen Purification Unit Project

Recently, Dakote Energy [Hydrogen Maple (China) Holdings] won the bid for the pressure swing adsorption unit of the 12,000 Nm³/h proton exchange membrane fuel cell–grade hydrogen purification system project at Shanxi Woneng Chemical Technology Co., Ltd., a subsidiary of Hangzhou Oxygen Group Co., Ltd. This unit represents the largest single, industrial-scale hydrogen production facility currently under construction in China for use in proton exchange membrane fuel cells. The project is being implemented under an EPC contracting model, with core equipment delivered as highly integrated skid-mounted modules, thereby effectively meeting the demand for short construction timelines in hydrogen energy projects. The project leverages Dakote Energy’s independently developed pressure swing adsorption (PSA) technology for hydrogen purification, along with specialized high-purity hydrogen-grade adsorbents, to produce hydrogen that meets the quality requirements stipulated in the national standard GB/T 37244-2018 “Fuel Hydrogen for Proton Exchange Membrane Fuel Cell Vehicles.” This hydrogen will serve as the core hydrogen supply source for Hangzhou Woneng Hydrogen Technology Co., Ltd.’s large-scale, integrated “hydrogen-electricity” energy island project. The project is scheduled for completion and commissioning in August 2024. Upon implementation, it will support Hangzhou Woneng Hydrogen Technology Co., Ltd. in developing a comprehensive, large-scale “hydrogen-electricity” energy island that integrates hydrogen refueling, electric vehicle charging, and natural gas filling. The hydrogen purified using Dakote Energy’s PSA technology can effectively meet the energy-supply needs of various types of hydrogen-powered vehicles and other end-use applications, significantly enhancing the economic value of rich-hydrogen tail gases while accelerating the development of the local hydrogen industry chain, fostering a regional green ecosystem, and contributing to the optimization and upgrading of the local economic structure. This project will become a flagship initiative in the fields of new energy and smart logistics in the region, playing a vital role in energy conservation, emissions reduction, and the achievement of the dual-carbon goals. Dakote Energy adheres to the principles of quality first, customer paramountcy, and reputation above all else. The company is committed to ensuring that project construction proceeds safely, efficiently, and to the highest quality standards, striving through concrete actions to deliver outstanding projects, enhance the company’s image, and successfully complete all project objectives. This unit employs our company’s independently developed technologies: — Pressure Swing Adsorption (PSA) technology for hydrogen purification Key features and advantages: — Utilizes multiple proprietary, specialty adsorbents developed and manufactured in-house, delivering performance more than 30% superior to conventional adsorbents; — Employs a patented, self-developed pressure swing adsorption process, offering flexible operation, safe and stable performance, and a compact footprint; — Achieves high hydrogen recovery rates, low energy consumption for hydrogen purification, and reduced operating costs; — The hydrogen purification technology is well-established, with extensive project track record and rich experience in engineering design and plant operations.

Good News┃Dakote Energy Awarded the Title of “2023 Advanced Unit for Civilized Construction of Projects”

On January 20, 2024, at the 2023 Annual Commendation Ceremony held by the project department of Guizhou Qixin Industrial Co., Ltd., the TSA purification unit for synthetic ammonia equipment under the coal deep-processing and comprehensive utilization project undertaken by Dakote Energy on an EPC basis received unanimous recognition from the client during the construction and installation phase. In response, the client conferred upon Dakote Energy the honorary title of “2023 Advanced Unit for Civilized Construction.” The company will continue to devote itself wholeheartedly to the project, rigorously managing project quality, safety, and schedule to ensure the successful completion of all project objectives. This project employs temperature swing adsorption (TSA) technology—developed and manufactured in-house by Dakote Energy—for the removal of tar, benzene, and naphthalene, along with its core adsorbent products. The development of this technology has undergone multiple rounds of innovation, culminating in the successful R&D in 2017 of the third-generation DKT-30D/B specialized adsorbent for benzene and naphthalene removal via TSA, which has since been successfully applied in numerous coking projects, achieving significant breakthroughs in purification performance and service life. To date, this technology and its core products have been successfully deployed in a wide range of similar projects, including those at Shaanxi Longmen Coking, Xinjiang Xinhui Gorge, Shanxi Woneng, Inner Mongolia Black Cat (Phases I and II), Shanxi Yaxin, Shanxi Yixin, Shanxi Tongzhou, Anyang Shunli, Donghai New Energy, Inner Mongolia Guangju, Zhongjin Taihang, Inner Mongolia Hengkun, Guizhou Meijin (Phases I and II), and Guizhou Qixin, among others. This project utilizes our company’s independently developed technology: Temperature Swing Adsorption (TSA) Key features and advantages: Optimal process design allows for the selection of single-stage or multi-stage adsorption beds based on the composition and concentration of impurities in the gas stream, ensuring ideal purification performance; Sophisticated adsorption tower design—including optimal tower diameter-to-height ratio, uniform gas distribution, and effective mechanical water separation—effectively prevents undesirable phenomena such as channeling, bypass flow, and entrainment of mechanical water into the adsorbent bed, thereby maximizing adsorbent efficiency; The use of a third-generation, self-developed and continuously improved specialized TSA adsorbent enables highly effective removal of impurity components (such as tar, naphthalene, and benzene) from the feed gas. This adsorbent boasts low bulk density, high porosity, large specific surface area, and enhanced adsorption capacity, while also facilitating easier and more thorough desorption, thus guaranteeing long-term, safe, and stable operation of the unit.
