Prediction Model for Surface Tension of Methyldiethanolamine (MDEA) Aqueous Solutions

In this study, Surface Tension of Aqueous Solution of Alkanolamines (MDEA and DEA) has investigated as a function of concentration and temperature (in the range 298.15-328.15K). Temperature dependence of surface tension is linear. Using Experimental Results published in literatures, line parameters have determined. Concentration dependence can be described, using an exponential function. The best coefficients for mentioned function calculated, using error minimizing method. Combination of temperature and concentration dependence results in an overall relationship for surface tension prediction. Such a relationship is useful in column design and optimization (minimizing problems such as flooding and foaming).
