NEW METHOD TO CORRELATE AND PREDICT VAPOUR-LIQUID EQUILIBRIUM DATA FOR SALT SOLUTIONS TO BE USED FOR HEAT PUMP SIMULATIONS.

Author(s) : RANE M. V., LALVANI S. B., HELMER W. A.

Summary

A METHOD IS PRESENTED TO CORRELATE EXPERIMENTAL VAPOUR-LIQUID EQUILIBRIUM (VLE) DATA FOR DIFFERENT AQUEOUS SALT SOLUTIONS. LOG-POLYNOMIAL EXPRESSIONS ARE USED FOR CORRELATION OF THE DATA. UP TO 5 DIFFERENT CURVES MAY BE USED TO FIT THE DATA OVER THE ENTIRE RANGE OF CONCENTRATION. CORRELATIONS ARE OBTAINED FOR AQUEOUS SOLUTIONS OF SODIUM HYDROXIDE AND A TERNARY NITRATE MIXTURE. THE RESULTS SHOW, FROM THE PERCENTAGE ERROR IN PREDICTING VLE DATA, THAT THIS TECHNIQUE IS MORE ACCURATE THAN EXISTING METHODS. ERROR IN CORRELATING VAPOUR PRESSURE AND SATURATION TEMPERATURE FOR WATER IS EXTREMELY LOW, THE AVERAGE ERROR BEING LESS THAN 0.1%. THE CRYSTALLIZATION CURVE IS ALSO OBTAINED FOR SODIUM HYDROXIDE-WATER SOLUTION.
