Global industry consumes vast quantities of nitrogen, oxygen and argon annually, all of which is obtained from the air around us. There are two main techniques used to separate the two primary gases from the air. These processes are cryogenic separation and (vacuum) pressure swing adsorption [(V)PSA].
