When helium is being produced for commercial use, purification is a crucial cog in the machine.
For nearly all production across North America and more widely, relatively small concentrations of helium are being extracted from natural gas resources and purified.
The process to make this happen takes in well-established technologies like pressure swing adsorption, cryogenics, and membranes – often in some combination, depending on the characteristics of the natural gas at the source.
