Helium Recovery System
Helium recovery is a cost saving in processes requiring the use of pressurised helium gas.
A recovery system's main components are:
- A backing helium economiser, capable of reusing up to 70% of the helium.
- A low pressure receiver tank, commonly a flexible globe that operates at atmospheric pressure.
- A helium compressor, with output pressure of up to 200 bar.
- A high pressure tank, where the compressed helium is stored
- A purity analyser, measuring gas thermal conductivity, which guarantees that the Helium concentration is adequate.
- A drying filter, to remove any humidity transported in the helium.
- An oil and particle filter that prevents contamination of the helium.
- A gas mixing unit, normally mixing He and N2, in the required proportions.
- An automatic control system for the entire system.
