EVALUATION OF THERMODYNAMIC PROPERTIES OF BINARY FLUID MIXTURES.

Author(s) : BORDE I., JELINEK M.

Summary

FOR NONELECTROLYTE REFRIGERANT-ABSORBENT COMBINATIONS, VAPOUR-LIQUID EQUILIBRIA DATA ARE MEASURED AND REDUCED TO THERMODYNAMIC PROPERTIES. NONIDEALITIES IN THE VAPOUR PHASE ARE DESCRIBED BY A VIRIAL EQUATION OF STATE, WHICH RELATES THE COMPRESSIBILITY FACTOR TO THE INDEPENDENT INTENSIVE VARIABLES OF COMPOSITION, TEMPERATURE, AND PRESSURE OR DENSITY. WITH THE CALCULATED EXCESS ENTHALPIES AND ENTROPIES, THE ENTHALPY-CONCENTRATION AND EXERGY-CONCENTRATION DIAGRAMS WERE CONSTRUCTED AND EXEMPLIFIED BY THE PAIR R22-MPL (N-METHYL-2-PYRROLIDONE). THE INFLUENCE OF SEVERAL THERMODYNAMIC PROPERTIES, AND ESPECIALLY THE EXCESS ENTHALPY, ON THE TOTAL PERFORMANCE OF ABSORPTION UNITS WAS ANALYZED WITH THE VIEW OF ESTABLISHING A DATA BASE TO ENABLE PREDICTION OF THE PERFORMANCE OF DIFFERENT BINARY COMBINATIONS IN ABSORPTION SYSTEMS.
