Abstract: The liquefaction method has become increasingly important in the natural gas trade as a result of both the cost and application difficulties associated with pipe transfer. In this study, enhanced exergy analysis of the cryogenic method used in the liquefaction of natural gas is discussed. When each component is examined, the highest exergy destruction was obtained in the turbine as 1,164 kW. The exergy efficiency of the overall system was calculated as 52.52%. In this study, the most significant consequence of exergy destruction n the turbine was discovered to be caused by unavoidable exergy destruction.

Keywords: liquefied natural gas; LNG; enhanced exergy analysis; liquefaction system; cryogenic.
