Abstract
Monoethanolamine solutions is one of several chemicals used for the absorption of acid gases since 1930. Physical and chemical
properties of these amine solvents have also been studied by various research groups. One of the important thermodynamic data
is surface tension, and in this paper, an evaluation onto techniques used to represent experimental surface tension data of MEA
solutions were performed. Surface tension of aqueous MEA solutions were measured at temperatures between (303.15 and
338.15) K and compared with values from literature. Three different methods were used to correlate the experimental data.
Analysis of suitability of these methods is presented in this paper and impact of the data deviation on engineering calculations
will be discussed.
