The effect of ultrasonics on the dewaxing of oil

  • Published:
Chemistry and Technology of Fuels and Oils Aims and scope

Conclusions

  1. 1.

    Optimum conditions have been established in laboratory experiments for the ultrasonic irradiation of distillate raffinates which enables the filtration rate of suspensions to be raised by a factor of 1.5–2 and the oil content in slack wax to be lowered by a factor of 2, with a corresponding increase in the yield of dewaxed oil.

  2. 2.

    The use of ultrasonic processing raises the dewaxing efficiency not only for high-sulfur feedstock but also for non-sulfur feedstock.

  3. 3.

    Under the irradiation conditions used by us residue feedstock filters 1.5–2 times worse than if ultrasonics are not used. The extent of deoiling of petrolatum with ultrasonic irradiation and the yield of dewaxed oil is higher than in experiments in which ultrasonics are not used.
