  • Patent number: 8480859
    Abstract: An apparatus to decrease viscosity of crude oil or bitumen and increase the rate of fractional extraction by breaking the high molecular chains in crude oil or bitumen undergoing treatment which includes a flow of crude oil or bitumen inside the treatment unit under simultaneous affection by cavitations and vibrations on different frequencies and between at least two opposite conical jets formed inside the diffusers having the same axis of symmetry and interacting with each other under the conditions of an auto-oscillations of the periodic backward flows of fluid inside each conical jet due to a periodic negative pressure inside each conical jet and the periodic negative pressure is determined in accordance with the following formulae: P a = P 0 - ? ? ? ? ? V 2 2 , ? wherein ? ? V = f ? ( D 4 - 2 ? R ) Sh , Pa is negative pressure in backward flow between the opposite conical jets.

  • Patent number: 7059591
    Abstract: The method and apparatus for making a micro-dispersed gas-liquid mixture which includes a gas-liquid ejector unit, a cavitation unit and a jet dispersing unit installed in a sequence. All above referenced units are installed into a cylindrical housing which in turn includes bottom and top covers and also has a first partition having a conical orifice separating a gas-liquid ejector unit from a cavitation unit and a second partition separating a cavitation unit from a jet dispersing unit. The gas-liquid ejector unit has an inlet located at the bottom of the cylindrical housing for liquid and the inlet located on side surface of housing for gas, these being between bottom cover of the housing and the first partition. In addition, the inlet for liquid is a nozzle the top having both outside and inside parts of which are adapted to the conical orifice of first partition to provide a required flow-rate of an ejected gas through the gas inlet.
