Summary

THE RESULTS SUGGEST THAT THE SYSTEM WITH THE SMALLER COLUMN TEMPERATURE LIFT IS THE MOST ECONOMICALLY ATTRACTIVE WHEN PAYBACK PERIOD (PBP) IS THE MAIN ECONOMIC CRITERION. FOR TYPICAL CONDITIONS CONSIDERED, PBP VALUES ARE 2 YR FOR THE METHANOL-ETHANOL SYSTEM, 2.6 YR FOR THE ETHANOL-WATER SYSTEM AND 5 YR FOR THE METHANOL-WATER SYSTEM. FOR ACCEPTABLE ECONOMIC CONDITIONS, RANKINE HEAT PUMP EFFECTIVENESS FACTOR OF THE SYSTEM SHOULD BE AT LEAST 0. 5, AND THE RUNNING TIME SHOULD BE MORE THAN 5,000 H/YR. THE REFLUX RATIO HAS LITTLE INFLUENCE ON THE ECONOMICS OF THE HEAT PUMP ASSISTED DISTILLATION SYSTEM.
