The dewaxing of oils using ultrasonics

  • 13 Accesses


  1. 1.

    It has been established that the ultrasonic irradiation of distillate oils subjected to dewaxing, using controlled dilution and MÉK as solvent, enables this process to be intensified to a considerable extent.

  2. 2.

    In the two-stage dewaxing of irradiated suspensions a highly deoiled wax is obtained besides the dewaxed oil. The irradiation of a suspension before the first stage enables filtration to be intensified in both stages.

  3. 3.

    Narrowing of the feedstock fractional composition enables the dewaxing properties to be greatly improved. The use of ultrasonics raises the dewaxing quality still further.
