Liquefaction of gases. The process of refrigerating a gas to a temperature below its critical temperature so that liquid can be formed at some suitable pressure, also below the critical pressure. Gas liquefaction is a special case of gas refrigeration. The gas is first compressed to an elevated pressure in an ambient-temperature compressor. As an example of the latter, a "major commercial application of liquefaction is the liquefaction of air to allow separation of the constituents, such as oxygen, nitrogen, and the noble gases." Another is the conversion of solid coal into a liquid form usable as a substitute for liquid fuels. LIQUIFICATION OF GASES We all are familiar with the different phases of matter viz. gas, liquid and solid. You have learned that the basic difference between these phases is the strength of inter-.

Liquefaction Of Gases has an wide importance. Thomas Andrews investigated the complete relationship between volume- temperature and pressure of a substance in gaseous as well as liquid state by studying the behaviour of carbon dioxide. Many gases can be put into a liquid state at normal atmospheric pressure by simple cooling; a few, such as carbon dioxide, require pressurization as well. Liquefaction is used for analyzing the fundamental properties of gas molecules (intermolecular forces), or for the storage of gases, for example: LPG, and in refrigeration and air conditioning. Gases such as nitrogen, oxygen and methane require the use of very low temperatures to liquefy and store them at relatively low pressures. To achieve this, a whole range of cryogenic technologies has been developed to ensure the economical liquefaction of gases. LIQUIFICATION OF GASES We all are familiar with the different phases of matter viz. gas, liquid and solid. You have learned that the basic difference between these phases is the strength of inter-. The study of the compression and expansion of gases is important in the liquefaction of gases. The principles behind refrigeration are based on the cooling of a gas as it expands, and the cooling process absorbs heat from the surroundings and thereby cooling the surroundings.
