Air separation - Wikipedia

Pure gases can be separated from air by first cooling it until it liquefies, then selectively distilling the components at their various boiling temperatures. The process can produce high purity gases but is energy-intensive. This process was pioneered by Carl von Linde in the early 20th century and is still used today to produce high purity gases. He developed it in the year 1895; the process remained purely academic for seven years before it was used in industrial applications for the first time (1902).

Cryogenic Separation - an overview ScienceDirect Topics

Cryogenic separation is a commercial process that takes place at very low temperature, where the component of feed gas starts to liquefy [76–81].An additional compression and cooling for the feed gas is necessary for process operation. Cryogenic process for separation involves cooling of the gas to a very low temperature so that CO 2 can be liquefied and separated [2].

This is how

C. As it expands in the separation columns, it cools down still further (reversed bicycle pump effect). As a result it liquefies to some extent (the temperature being lower than the boiling point). Cooling and separating By means of the separation column, the air is separated into its components. This is a purely physical process,
