In this work, a simple Arrhenius-type function that is easier than existing approaches, because it is less complicated and has fewer computations, and is suitable for process engineers, is presented here for the estimation of methanol loss in paraffinic hydrocarbons, as a function of temperature and methanol concentration in the water phase. The solubility of methanol in paraffin hydrocarbons is calculated for temperatures between −30 °C and 50 °C and methanol concentrations in the water phase up to a mass fraction of 0.70. Estimations are found to be in excellent agreement with reliable data in the literature, with the average absolute deviation being 2.12%. The tool developed in this study can be of immense practical value for the engineers and scientists to have a quick check on the loss of methanol in paraffinic hydrocarbons phase under various conditions without opting for any experimental measurements. In particular, chemical and process engineers would find the approach to be user-friendly with transparent calculations that involve no complex expressions.
