Cryogenic Air Separation Plant (O₂, N₂, Ar na ol liklik ges)

Wanpela 'air separation plant' (ASP) i save separetim win bilong win i go long ol bikpela samting bilong en, olsem 'nitrogen' na 'oxygen', na sampela taim tu 'argon' na ol narapela 'rare inert gas'.

Rot we planti man i save yusim long separetim win em long 'low-temperature distillation. Dispela rot em ol i save yusim long seperetim ol hai-puriti oksijen, naitrojen, na argon insait long ol narapela indastri. Na tu, ol samting we i save kamapim ol liklik ges, olsem neon, krypton, na xenon, em i kam long rot bilong rausim win long rot bilong tupela 'distillation columns'.
