Abstract
The method of statistical entropy analysis of small-scale LNG plants is developed on the basis of the first and second laws of thermodynamics. The analysis stages are shown and the main calculation relationships are given. Average statistical data are used in the calculations to indicate the ranges of possible variations of quantities, such as ambient temperature, under-recuperation in heat exchanger, heat influxes from the surroundings, efficiency of compressors and expanders, etc. The proposed method can be used to calculate the work required to compensate for the entropy produced in the core units of the plant and so to determine as early as in the design stage the most power consuming components for their updating or replacement.
