STUDY OF HEAT AND MASS TRANSFER IN PULSED COLUMN FOR GAS-LIQUID-LIQUID ABSORPTION SYSTEM.

Author(s) : PURWANTO W. W., PREVOST M.

Summary

AN INVESTIGATION OF SIMULTANEOUS HEAT AND MASS TRANSFER IN A THREE-PHASE SYSTEM (TWO IMMISCIBLE LIQUIDS AND ONE VAPOR PHASE), EQUIPPED WITH A PULSED PERFORATED PLATE COLUMN, IS REPORTED. THIS SYSTEM ESSENTIALLY CONSISTS OF AN ABSORPTION OF WATER VAPOR (GAS DISPERSED PHASE) IN LITHIUM-BROMIDE SOLUTION (LIQUID CONTINUOUS PHASE) ACCOMPANIED BY LARGE HEAT EFFECTS AND THE DIRECT CONTACT HEAT EXCHANGE BETWEEN THIS PHASE AND DODECANE (LIQUID DISPERSED PHASE). IN THE ABSENCE OF SEPARATING WALLS, IT HAS THE APPARENT ADVANTAGE OF REDUCING RESISTANCE TO HEAT TRANSFER AND CORROSION PROBLEMS. A MODEL DESCRIBING TRANSFER PROCESSES HAS BEEN ESTABLISHED. THIS MODEL IS BASED ON CONSERVATION EQUATIONS (MASS AND ENERGY). STEADY-STATE TWO-LIQUID TEMPERATURE PROFILES AND THE CONTINUOUS PHASE CONCENTRATION PROFILE WERE MEASURED EXPERIMENTALLY.
