Claude's Method of Liquefaction of Gases
Claude's method is more efficient than Linde's method. The compressed gas in the insulated vessel (i.e., under adiabatic conditions) is partly used to do work against a piston in a cylinder and partly expanded through a valve. The energy required for adiabatic expansion is supplied by the gas molecules. The energy loss of the gas molecules results in their cooling. The cooled gas obtained by adiabatic expansion is used for cooling the incoming gas in the heat exchanger. The process is repeated till the gas is liquefied.
