摘要

液氢能量密度高、运输效率高，成为了氢规模化储运的重要方式。为降低氢液化工艺能耗，提高效率，以双混合制冷剂的氢液化工艺为基础，提出了一种LNG预冷的新型氢液化工艺。该工艺利用LNG冷能预冷，通过混合制冷剂布雷顿循环进行深冷，深冷段采用了四级压缩、三级膨胀和三级正仲氢转化。采用Aspen HYSYS软件对工艺进行了模拟，并利用粒子群算法进行了优化。结果表明，优化后工艺的比能耗可达5.263 kW·h/kg，㶲效率可达58.18%，优于大部分已知氢液化工艺系统。该工艺流程相对简单，能耗低、效率高，可为氢液化工艺的设计和改进提供新的思路，同时拓展了沿海LNG接收站LNG冷能回收利用的新途径。

Abstract

Liquid hydrogen has high energy density and high transportation efficiency, making it an important approach for the large-scale storage and transportation of hydrogen. In order to reduce the energy consumption of hydrogen liquefaction processes and improve efficiency, a new hydrogen liquefaction process based on LNG pre-cooling using dual mixed refrigerants has been proposed. This process utilizes the cryogenic energy of LNG for pre-cooling and employs a Brayton cycle with mixed refrigerants for deep cooling. The deep cooling section involves four-stage compression, three-stage expansion, and three-stage conversion of ortho-para hydrogen. The process was simulated using Aspen HYSYS software and optimized using the particle swarm optimization algorithm. The results show that the optimized process has a specific energy consumption of 5.263 kW·h/kg and an exergy efficiency of 58.18%, surpassing most known hydrogen liquefaction processes. This process has a relatively simple structure, with low energy consumption and high efficiency, which can provide new insights for the design and improvement of hydrogen liquefaction processes and expand the utilization of LNG cold energy recovery in coastal LNG terminals.
