Replies are encouraged – feel free to discuss! ------------------------------------------- China’s first set of industrial-grade helium liquefaction equipment with a capacity of 140 L/h, along with the first 10 m3 liquid helium storage tank, have passed inspection. On December 6, 2022, the China General Machinery Industry Association held an inspection meeting in Beijing, Chengdu, and Ordos, using both on-site and video conferencing methods, for the “Industrial-grade helium liquefaction equipment for high-pressure helium ultra-low temperature purification” (140 L/h industrial-grade helium liquefaction equipment and 10 m3 liquid helium storage tank), which was developed by Sichuan Air Separation Equipment (Group) Co., Ltd. The meeting was chaired by Huang Li, president of the China General Machinery Industry Association. Sui Yongbin, former chief engineer of the China Machinery Industry Federation, served as the head of the expert panel of the appraisal committee. The panel was composed of experts from organizations such as the China Machinery Industry Federation, Beijing Aero-Engine Research Institute, Sinopec North China Bureau, Yanchang Petroleum, a unit of the People’s Liberation Army, the School of Energy Engineering at Zhejiang University, the School of Energy and Power Engineering at Huazhong University of Science and Technology, CNPC Planning Institute, Xichang Satellite Launch Center, China Academy of Engineering Physics, CNPC Southwest Branch, Tasixi Natural Gas Plant of CNPC’s Tarim Oilfield, and Shenmu Zhongsheng Energy. The experts present listened to the summary report on the project development provided by the development team, and reviewed the relevant technical documents. Some experts visited the installation site before the conference to witness its industrial operation. The appraisal committee believes that China’s first set of industrial-grade helium liquefaction equipment with a capacity of 140 L/h has been developed; this equipment features a technology for the ultra-low-temperature purification of high-pressure helium, enabling the simultaneous production of high-pressure, high-purity helium and liquid helium. The purity of the high-purity helium product reaches 99.9999%, while the recovery rate is 99.6%. In full liquefaction mode, the output of liquid helium is 142 L/h. The purity and recovery rates of the helium products produced by this equipment are at the international leading level. The first 10m3 liquid helium storage tank developed in China features a high-vacuum multi-layer insulation structure equipped with a fully enclosed cryogenic shield made of liquid nitrogen, as well as a multi-point segmented combined support technology; these elements effectively reduce heat loss from the liquid helium storage tank, and its key performance indicators have reached international advanced levels. The complete set of equipment possesses independent intellectual property rights, breaking through foreign technical barriers; it is of great significance for ensuring China’s helium supply, offers significant economic and social benefits, and has broad prospects for widespread application.
