Measurement of mono ethylene glycol volume fraction at varying ionic strengths and temperatures

The volume fraction (Fvm), nD, EC, and TDS of MEG solutions have been measured at (283.15, 298.15, and 323.15) K, (10-100) vol. %, and at (0, 0.125, 0.25, 0.5, 1.0) M NaCl total volume of solution) ionic strength (IS). The experimental results were then correlated to develop a simplistic model capable of estimating the volume fraction of MEG mixtures at varying ionic strengths. The proposed models will therefore allow a quick and convenient method for the determination of MEG concentrations in the field to quickly identify undesirable changes in produced lean MEG concentration.
