small hydrogen liquefaction device (≤2tpd)
large-scale hydrogen liquefaction plant (≥2tpd)
hangyang has more than 50 sets of vertical and horizontal hydrogen compressors, which are widely used in coal chemical and petrochemical fields.the hydrogen liquefaction unit adopts the mature compressor model of hangyang, and the compressor efficiency is comparable to that of similar imported products hangyang compressor equipment cost is 30~50% lower than similar imported products
hydrogen plate fin heat exchanger
hangyang plate plant has carried out heat exchanger technology research and brazing technology upgrade. the maximum design pressure is 13.5mpa, and the leak rate is increased to <10-9 pa m³/s
hydrogen expander (oil bearing)
the first domestic hydrogen booster turboexpander and the first domestic hydrogen expansion generator set are widely used in the field of alkane dehydrogenation
in 2018, it passed the appraisal of scientific and technological achievements, filled the domestic gap, and realized the localization of imported high-end devices.
advantages: single-stage high enthalpy drop, high rotational speed, zero leakage of seal, high reliability
as of 2021, the performance of hydrogen/hydrogen-rich expanders has reached 18 sets
helium gas shaft expander
hangyang has equipped several sets of helium liquefaction equipment with high-speed helium gas shaft expanders with a maximum speed of 256,000rpm
liquid hydrogen/liquid helium valve
hangyang tooling pump valve co., ltd. has developed regulating valves and manual valves for liquid hydrogen/liquid helium media, which are matched with several sets of liquid hydrogen and liquid helium devices such as guofu hydrogen energy, aerospace 101, and chinese academy of sciences.
the liquid hydrogen test shows that the liquid hydrogen valve has good operating performance, valve seat sealing performance, adjustment performance, leakage fugitiveness and low heat consumption under low temperature operating conditions under 20k ultra-low temperature conditions.
drafting industry standards for liquid hydrogen valves
