Although it principally resembles a refrigerator, production of LNG is a complex and energy demanding process. At Hammerfest LNG the Statoil/Linde developed mixed fluid cascade process liquefy natural gas from gaseous to liquid at temperatures at 110 K. From an operational perspective, the process i...
