초록정보

The recovery of CFCs and HCFCs using absorption process was investigated. In this experiment, the solubility measurement and the absorption process were performed. The solubilities of chlorodifluoromethane(R-22) and dichlorodifluoromethane(R-12) in organic solvents were measured in the range of low pressure and several temperatures (278.15 - 338.15 K). Organic solvents used in this system are olive oil and oleic acid. Henry's law is applied in the lower temperature range and the solubilities of R-22 show negative deviations from Raoult's law. In this study temperature and pressure dependence are correlated using the low pressure data reduction. The correlation of gas solubility data, using Krichevsky-kasarnovsky equation and Van't Hoff expression are obtained. Values of Henry's constant, partial enthalpy and partial entropy in organic solvents have been determined for both gases. The solubilities increase with increasing pressure and decreasing temperature and both gases are more soluble in olive oil than in oleic acid. Higher solubilities of R-22 than those of R-12 were explained qualitatively by the concept of hydrogen bonding with the various oils. Also the absorption in packed column was performed at determined conditions. In this study, characteristics of hydraulic and mass transfer were investigated in a packing tower of height using 1/4 inch glass rasching ring. Test systems of R-22/olive oil and R-12/olive oil were studied experimentally under steady state. The scope of test included investigation of dry and wetting pressure drop, physical law and absorption efficiency as a function of gas and liquid load. The gas flow rate was 10 - 30cm/s and the relation of overall mass transfer coefficient to gas and liquid flow rates was obtained by the empirical equation.
