DEVICE FOR REDUCING VISCOSITY OF OIL AND PETROLEUM PRODUCTS Russian patent published in 2017 - IPC F17D1/16 

FIELD: agriculture.

SUBSTANCE: invention relates to the oil industry and can be used in the extraction and transportation of heavy crude oils and petroleum products. The apparatus comprises an ultrasonic piezoelectric module connected to the pipeline by means of flanges ,consisting of a cylindrical piezoelectric element with a segment of metal pipe disposed inside, having an acoustic contact with the piezoelectric element, wherein the diameters of the cylindrical piezoelectric element and of the metal pipe segment, as well as the resonant frequencies of the ultrasonic vibrations source, correspond to the condition of excitating the cylindrical standing wave in the segment of the metal pipe filled with oil.

EFFECT: invention provides increasing efficiency of the process of extracting and pumping heavy oils and petroleum products due to reducing their viscosity as a result of the simultaneous cavitation and thermal impact of the ultrasonic standing waves of high intensity without increasing the total power consumption.
