  • Cryogenic liquefier/chiller
    Patent number: 6591632
    Abstract: A system for chilling and/or liquefying a fluid wherein a multicomponent refrigerant in a circuit is compressed, condensed, expanded and warmed to cool one or more portions of the fluid which are then turboexpanded to generate refrigeration and which are then used to provide refrigeration to a remaining portion of the fluid so as to chill and/or liquefy that remaining portion.
    Type: Grant
