A physicomathematical model for electrohydrodynamic spraying (EHDS) of a conductive liquid and the mass transfer in a parallel plate electrodes system of an EHDS distillation column is presented. The influence of the electric field on the formation and general characteristics of the finely dispersed aerosol flow of the conductive liquid in EHDS distillation columns has been determined from the model. It allows to explain in detail the mechanism of the influence of the electric field on the mass transfer in the gas-liquid system. In addition. the maximum possible liquid flow rate in the mass transfer section of the EHDS distillation column has been estimated. The role of process parameters is discussed in detail.
