Experimental and theoretical study of pool boiling heat transfer to amine solutions

Abstract

Abstract-In this investigation, a large number of experiments have been performed to measure the nucleate boiling heat transfer coefficients of water/diethanolamine (DEA) and water/monoethanolamine (MEA) binary solutions. Based on these experimental data, effects of physical properties such as surface tension and viscosity of mixtures on nucleate boiling heat transfer coefficients and also on bubble dynamics have been discussed. Meanwhile, some photographs have also been selected which illustrate the behaviours of bubbles near the heat transfer surface. In this article, a new correlation has been developed on the basis of the correlation of Stephan and Körner which is known as a successful correlation for the prediction of nucleate boiling heat transfer coefficients of mixtures. Comparison of the prediction of this new correlation with experimental data indicates that this modification can significantly improve the performance of the Stephan and Körner correlation.

Influence of thermodynamic models on the prediction of pool boiling heat transfer coefficient of dilute binary mixtures

“…For boiling of liquid mixtures with high heat of solutions this correlation overpredicts the data over all ranges of fractions. Recently, Peyghambarzadeh et al [2] proved that this tuning parameter is a function of heat flux. Calus and Rice [3] reported data on boiling under free convection for isopropanol/water and acetone/water binary mixtures and for the three pure components.…”

Investigation of Mixed MEA-Based Solvents Featuring Ionic Liquids and NMP for CO2 Capture: Experimental Measurement of CO2 Solubility and Thermophysical Properties

“…The binary mixture of water + MEA has been noted in the literature to be zeotropic. 63 Furthermore, water is far more volatile than MEA; given that the evaporation rates were determined at 373.15 K, it was assumed that the majority of the water content would evaporate prior to the evaporation of MEA. Based on this assumption, the individual evaporation rates of water and MEA were estimated.…”
