Abstract
The kinetics of the extraction of oil products (bitumen, oil, and fuel oil) from natural and model oil-bearing sands after ultrasonic treatment was studied. The effects of the process temperature, the nature and properties of the separated components, and the concentrations of the added reagents on the rate and extent of oil product extraction were also studied. The functional form of the dependences of the separation efficiency on the mean size of the solid particles and the working medium temperature was determined. The working solution of sodium silicate can be recycled in the separation, and its reuse can even accelerate the extraction of oil products at the first stage. Based on the obtained data, we created and tested a universal pilot apparatus for ultrasonic oil extraction from oil-bearing sands and the purification of soils contaminated with oil products.
