摘要

An entropy-statistical analysis of a 7 tons/h capacity small-tonnage CNG plant functioning in a cycle with external nitrogen expansion cooling demonstrated a probable value of the magnitude of thermodynamic perfection of 33%. Application of a rational multi-stage scheme with pre-cooling and the use of a compressor with isothermal efficiency 0.65 and turbine expansion engine with adiabatic efficiency 0.835 are responsible for the decisive contribution to achieving an increase in efficiency.
