Abstract�� With oil sand cleaning agent by self-made,separation on Inner Mongolia Zha Lai Te Qi oil under ultrasonic was performed.The effects of ultrasonic frequency,ultrasonic intensity,cleaning time,cleaning temperature on oil sand separating were investigated.Under ultrasonic cavitations,at ultrasonic frequency of 28 kHz,ultrasonic intensity of 7.06 W/cm~2,the ratio of cleaning agent to oil sand 0.8��1,system temperature 60 ��,cleaning time 13.0 min,the oil extraction rate achieved 94%.The result of the research proved that the oil extraction rate was improved greatly under the ultrasonic wave action.
