Summary

THE STUDY OF HEAT PUMPS WITH HEAT TRANSFER FLUID IS BASED ON THE USE OF THE H-LOG P CHART. IN DISTILLATION, THE DIMENSIONING OF A COLUMN FOR THE SEPARATION OF A BINARY MIXTURE BY PONCHON AND SAVARIT'S METHOD IS BASED ON THE USE OF THE ISOBARIC ENTHALPIC CHART (Z-H). THE SYNTHESIS OF THESE TWO DIAGRAMS INTO A THREE-DIMENSIONAL CHART (H-LOG P-Z) GIVES THE WHOLE PLOTTING OF THE CYCLE FOR A DISTILLATION COLUMN-HEAT PUMP SYSTEM. AN EXAMPLE IS GIVEN, CORRESPONDING TO THE DISTILLATION OF CYCLOHEXANE-N-HEPTANE ; THE CHARTS ARE DRAWN FROM A CALCULATION USING AN EQUATION OF STATE, THE MAIN STEPS OF WHICH ARE GIVEN. SUCH A REPRESENTATION MAY BE EXTENDED TO THE STUDY OF HEAT PUMPS WITH MIXED FLUIDS, WITH VARYING COMPOSITION.
