Mostra come i gas vengono estratti dall'aria in fase liquida, quindi separati grazie al processo di distillazione frazionata in un'unità di separazione dell'aria (ASU) industriale e poi compressi in bombole di gas.
I gas più tipici prodotti dalla distillazione: Azoto, Ossigeno e Argon (spesso chiamati "gas dall'aria" in contrapposizione ai gas prodotti da altre fonti, solitamente con un processo chimico)
