A typical helium recycle system is designed to take contaminated helium and remove impurities such as oxygen, nitrogen, and water, down to parts per million (ppm) levels for reuse in manufacturing applications. Recycle systems consist of particulate filters, a compressor system, catalytic reaction and condensate separation, temperature swing adsorption (TSA), and cryogenic adsorption. Applications include gas recovery from the titanium arc-melting industry, gas recovery from MRI equipment, and gas recovery from furnace cool down and inerting in metal production.
Helium recycle systems allow the reuse of contaminated gas, significantly reducing operating costs compared with "once-through" helium
Recycle systems are environmentally friendly because they enable the reuse of a strategic natural resource
TSA technology provides significantly lower process gas losses and less need for maintenance when compared to pressure swing adsorption (PSA) or membrane technology
Presently, there are 7 Cryo Technologies helium recycle systems in service in the titanium production industry.
