A New Tar Sand Recovery Process: Recovery Methods and Characterization of Products

Investigation of Thermal Conductivity and Heat Characteristics of Oil Sands Using Ultrasound Irradiation for Shortening the Preheating Time

“…This frequency was selected in accordance with previous studies and resonant frequency. [15][16][17][18][19][20][21][22] Standard deviation of the mean is less or equal to 0.1 C. DT includes initial temperature. Te shows that the rising temperature with ultrasound irradiation is higher at 0 mm (ch1, ch4).…”

Impact of ultrasonication time on elution of super heavy oil and its biomarkers from aging soils using a Triton X-100 micellar solution

“…Therefore, ultrasound is of undoubted interest as a promising method of influence in the processes of the separation of heterogeneous mixtures. Earlier studies have suggested that the application of ultrasound could significantly increase the efficacy of surfactants in eluting PAHs [10,11], DDT and PCBs [12], diesel fuel [13], and tar sand or oil products [14,15]. However, there have been no reports concerning the effects of ultrasonication time on the remediation of aging soils contaminated with super heavy oil and its biomarkers.…”

Oil sand processing by ultrasonic technique

“…Under the impact of pulsating cavitation bubbles and shock waves, the aggregates of the solid phase break up, erosion and cracks appear in the contaminant films sticking to the particles, and they separate in layers. Through the cracks the leaching solution containing surface active agents formed as a result of sonochemical reactions of the components of the oil products and reagents may infiltrate into the originally closed pores under the action of capillary forces intensified by ultrasonic effect [5][6][7].…”

Aqueous sodium silicate, carbonate, and hydroxide solutions with temperatures of 30-75°and a pH > 7 were used as the working dispersion medium.…”
