水电解制氢技术的工业应用
Industrial application of water electrolysis for hydrogen production
通过对碱性水电解制氢工业化生产进行研究,分析水电解制氢的反应机理;通过对核心电解槽设备的选型及电解水制氢装置的施工建设和调试运行,评估碱性水电解制氢技术的经济性。项目运行情况表明,4 000 Nm3/h水电解制氢装置实现成功投产,氢气纯度达99.99%。所制氢气通过输氢管道、管式槽车等送至玉门老市区化工园区企业,实现了从生产到销售的全流程贯通,电解槽制氢单位能耗为3.99 kW·h/m3,为中国石油在绿电制氢技术应用提供了更大的平台。
Through studying on the commercial hydrogen production via alkaline water electrolysis,the corresponding reaction mechanism is analyzed.The economic feasibility of alkaline water electrolysis technology for hydrogen production is evaluated by selecting core electrolyzer equipment,and constructing,commissioning and operating the water electrolysis to hydrogen plant.It is shown by the project operation situation that the 4 000 Nm3·h-1 hydrogen production plant via renewable energy-driven water electrolysis has successfully been put into operation.The produced hydrogen with a purity of 99.99% is transported through hydrogen pipelines and tube tankers to the enterprises in the chemical industrial park in old urban area of Yumen,Gansu,China,realizing the full process from production to sales.The unit energy consumption of hydrogen production by the electrolyzer is 3.99 kWh·m-3,providing a larger platform for PetroChina in the application of green electricity hydrogen production technology.
