随着氢能产业的快速发展，未来其对水的消耗量将会激增.质子交换膜(PEM)电解水制氢作为最有潜力的制氢工艺之一，其过程需要高品质淡水资源.反渗透海水淡化作为开源增量技术，是解决淡水资源紧缺的重要途经.为缓解电解制氢对高品质淡水的需求压力，本研究通过对膜集成工艺组合研究，以海水为原水，对比了不同膜集成工艺淡化处理效果和有无能量回收装置工艺的能耗情况.设计试验装置处理规模为40 m3/d，工艺流程主要包括介质过滤、三级反渗透和EDI，并采用高压泵能量回收一体机进行集成化设计.试验结果显示，产水电导率（25 ℃）≤0.1 mS/m，吨水电耗约为2.9 kW·h，与无能量回收相比能耗节约49%，形成适用于PEM电解水制氢用水的膜集成海水淡化工艺. |

With the rapid development of the hydrogen energy industry, its water consumption will surge in the future. PEM electrolysis of water for hydrogen production is one of the most promising hydrogen production processes, which requires high-quality fresh water resources. Reverse osmosis seawater desalination, as an open-source incremental technology, is an important way to solve the shortage of fresh water resources. To alleviate the demand pressure for high-quality fresh water in electrolytic hydrogen production, this study compared the desalination treatment effects of different membrane integration processes and the presence or absence of energy recovery devices using seawater as raw water through a combination of membrane integration processes. The designed experimental device has a processing capacity of 40 m3/d, and the process mainly consists of medium filtration, three-stage reverse osmosis, and EDI, with an integrated design using a high-pressure pump energy recovery machine. The experimental results show that the conductivity of the produced water (25 ℃) is ≤ 0.1 mS/m, and the power consumption per ton of water is about 2.9 kW·h. Compared with no energy recovery, it can save 49% of energy consumption, forming a membrane integrated seawater desalination process suitable for PEM electrolysis water hydrogen production water, providing technical reference for seawater desalination in hydrogen production water. |
