Hydrogen liquefier

Karol Olszewski (1846–1915) – design Władysław Grodzicki – constructor

1903, Kraków, Poland Jagiellonian University Museum, Collegium Maius

The presented device is a type of countercurrent choke apparatus in which condensation of gas occurs after its rapid expansion from high pressure to atmospheric pressure. Part of this gas was then liquefied, while the remaining, non-liquefied cooled gas was returned to the circuit as a coolant. This technique, based on the Joule-Kelvin effect and the countercurrent heat (cold) exchange, allowed liquefying hydrogen in a relatively simple manner.
