liquefaction of gases

Physics

The conversion of a gaseous substance into a liquid. This is usually achieved by one of four methods or by a combination of two of them:
1. (1) by vapour compression, provided that the substance is below its critical temperature;
2. (2) by refrigeration at constant pressure, typically by cooling it with a colder fluid in a countercurrent heat exchanger;
3. (3) by making it perform work adiabatically against the atmosphere in a reversible cycle;
4. (4) by the Joule–Thomson effect (see also Linde process).
Large quantities of liquefied gases are now used commercially, especially liquefied petroleum gas and liquefied natural gas.
