Abstract
In the liquefaction of a gaseous fluid wherein a refrigerant fluid having at least two components is used, at least two conditions parameters of the refrigerant fluid are determined. The determined values are used to control regulating members of the flow rates of the refrigerant fluid at specified operations of the liquefaction process.
