【Ten Years of Great Progress in Chemical Engineering Technology】038-2023: China’s first hydrogen liquefaction system equipped with domestic continuous heat exchangers was successfully commissioned
Thread Content
Ten years of rapid development in chemical processing equipment – praise for China’s prosperity and strength. This is just a starting point; more participation will make things even more lively. HaiChuan becomes even better with you all; we welcome everyone to join in the forum discussions. Happy May Day! A safe and secure Red May ********************************************* China’s first hydrogen liquefaction system equipped with domestic continuous heat exchangers was successfully commissioned. Recently, the first such system in China, developed by Aerospace Hydrogen Energy Technology Co., Ltd., was brought online successfully, producing liquid hydrogen on a steady basis. All key components, including the control system, catalysts, and continuous heat exchangers, are of domestic origin. This system is the third civilian hydrogen liquefaction system developed and commissioned by China’s aerospace industry since 2020.

The system has successfully addressed the design and implementation of the complex \"flow-heat-solid coupling\" processes in the hydrogen liquefaction process. It has achieved, for the first time in China, the engineering implementation of a continuous normal/parahydrogen conversion heat exchanger, featuring a more compact structure and a significantly improved insulation efficiency of its core component, the cryogenic tank； An advanced intelligent control logic that integrates fault diagnosis, automatic start/stop, and adaptive control under varying operating conditions was optimized and validated. After nearly 100 days of technical discussions and testing, as well as almost a year of efforts dedicated to the development of the equipment, and through rigorous process controls such as individual unit testing, system integration, purging, and system commissioning, the system was successfully brought online in one attempt. It operated continuously and stably for over 72 hours, achieving automated control throughout the entire start-up, operation, and shutdown process. This marks the growing maturity of China’s technologies in the design, manufacturing, integration, and testing of cryogenic industrial-grade equipment.
