The thermodynamic efficiency analysis of the installations for vapors condensation of the liquefied natural gas
The research results of the thermodynamic efficiency of installations for the vapors condensation of liquefied natural gas used in cryogenic long-term storage tanks are introduced. It is shown that the use of preliminary propane cooling allows to increase significantly the thermodynamic perfection degree of installations, and the maximum efficiency ratio is achieved by using a mixed cooling agent in a cycle with a multi-flow heat exchanger. In such a case highest power consumption for entropy production fall on the compressor and throttle.
