A new model for estimating mass transfer coefficients for the extraction of ethanethiol with alkaline solutions in packed columns

The mathematical model for estimating the mass transfer coefficients for the ethanethiol extraction from gasoline, with alkaline solutions was established by processing the data obtained in a laboratory and in a pilot plant experiment. It allows the estimation of overall mass transfer coefficients, taking into account the dispersed phase velocity, the concentration of NaOH solution, the specific area and the porosity of the packing. The model’s parameters were statistical tested in order to confirm the accuracy of the model.
