Study Notes
Air Separation
- Air is separated into its constituents via a two-step process.
- Liquefaction: Air is cooled to very low temperatures.
- Fractional distillation: Liquefied air is placed in a chamber attached to a fractionating column. Nitrogen has the lowest boiling point and is the first to boil off, hence it is collected at the bottom.
