Helium recovery and liquefaction

The indicated result will be the suggested number of helium gas tanks with 1000 liters volume, pressurized up to 5 bar. At a value above 5, we suggest using a high pressure recovery system (HPR), as the footprint of a corresponding medium pressure recovery system (MPR) would be much larger.
