Abstract

Using earlier results, as well as our own experiments, we have shown the existence of an optimum frequency in a demulsification process utilizing an AC electric field. within a frequency range of 20 Hz to 100KHz we have determined voltage curves with different insulation and emulsions, these demonstrate why demulsification by means of an AC field is more efficient than that of a DC field. By analyzing the data obtained in measurement of dielectric properties of the system, we found that fm is about the same of (omega)p instead of fp. To go into it seriously, we concluded that the optimum condition is T(m) = T(P), at whichresonance occurs in the system and hence it promotes coalescence.
