单词	liquefaction of gases
释义	liquefaction of gases 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) by vapour compression, provided that the substance is below its critical temperature; (2) by refrigeration at constant pressure, typically by cooling it with a colder fluid in a countercurrent heat exchanger; (3) by making it perform work adiabatically against the atmosphere in a reversible cycle; (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
