The remaining cooled gaseous portion is returned through the other side of the heat exchanger where it precools the incoming high-pressure air before returning to the compressor. The liquid portion is usually distilled to produce liquid oxygen, liquid nitrogen, and liquid argon. Other gases, such...

For this, the air sample was first liquefied and after that introduced to the process of boiling. The gases that were liberated during the process of boiling were captured. Three gases that were distinctly identified were oxygen, nitrogen, andargon. Krypton gas was also discovered at that time...
Oxygen gas is commercially extracted by fractional distillation of liquefied air[1]. It can also be obtained by passing dry air through zeolite, a microporous mineral that can absorb nitrogen but leave oxygen[1]. Passing the air through a selectively permeable ceramic membrane can produce highly ...
