The PSA hydrogen purification unit for the integrated alkane resource utilization facility project at Donghua Energy (Ningbo) New Materials Co., Ltd., which was undertaken under the EPC contract by Southwest Chemical Research and Design Institute Co., Ltd. (hereinafter referred to as “Southwest Institute”), was successfully commissioned after being fed with material. Author/Source: Gasification World; Date: 2021-10-20; Clicks: 10. Recently, the PSA hydrogen purification unit in question was successfully put into operation following the completion of the feeding process. The purity of the hydrogen product is greater than 99.999%, meeting the requirements specified in the contract as well as the standards for high-purity hydrogen and hydrogen used in fuel cells. It is currently the largest hydrogen purification facility in China that meets both these standards. This high-purity hydrogen product is used in hydrogen fuel cell applications as well as for the supply of specialty gases. The hydrogen products have now been successfully loaded onto vehicles, and the entire production process is operational; they will serve the development of the hydrogen energy industry in the Yangtze River Delta region. It is understood that this unit is located in the Daxie Development Zone of Ningbo City, Zhejiang Province, and its designed raw gas processing capacity is 8,890 Nm3/h. It represents the fourth pressure swing adsorption unit that Southwest Research Institute has successfully installed and put into operation at Donghua Energy. Currently, all four pressure swing adsorption units are operating safely and stably.
