Cavitation technology application


Cavitational effect is accompanied by microexplosions, ultrasound and also by mechanical cuts and encounters from exposure of the hundred of cuts pairs which are moved towards each other with the high linear speed. The value of that speed is reach to a few dozen of meters per seconds which gives a possibility to cut dispersed matters to the smallest microparticles. In fact it is a micropulse. Per one minute occur hundreds of thousands of micropulses.

The methods of petroleum and petroleum residues processing are based on phase transition which is typical for dispersed system. An effect on phase transitions kinetics can be achieved by chemical agents and physical fields. As a result the nuclear radius is changed, changed also the thickness of adsorptive solvation sphere of compound recurring unit. This unit is an element of petroleum dispersed system. These processes allow increasing the desired petrochemical products yield, improve their quality and reduce energy consumption.



Light fuel product yield increasing


The idea of long-chain organic compounds crushing into short-chain which create a new compounds leads to creation of light fuel products is not new. Those researches were started in the 1960s by soviet scientists. But today, at the time of high prices on the petroleum and its processing cost increase, cavitational technologies are particularly topical.


For today the method of cavitational oil processing is most qualitative. Specific density of light fuel products is increased after cavitational treatment of petroleum.




Vortex Cavitational Hardware


The main direction of an ultrasonic vortex cavitational generator application (or AVS unit by PC GlobeCore) is petroleum industry.


Cavitational hardwares are used for creation of oil-fuel, oil-mazut mixtures and emulsions. These emulsions are often used to increase the combustion efficiency or utilization of watered fuels.


Cavitational process has a great destruction power which can be used for desintegration of solid substances contained in liquids.


A hard spot crushing is one of the applications of this process which is included to heavy fuels.


This process is also used in order to increase the caloric content of the heavy fuel oil.


Cavitation can be used in fuel treatment process. During this treatment fuel obtains additional purification and at the same time fraction ratio is redistributing to the light fraction. The tests of such fuel are demonstrated decreasing of soluble gum amount.


After treatment by AVS is increasing the quality and caloric content of fuel. As a result we can reach complete fuel burning and decreasing the mass of contaminants. Investigation of cavitation influence on quality of fuel is still urgent and that research is conducted by different private companies and research institutes.


Cavitational devices can increase hydrocarbon fuel viscosity. As a result necessary heating value is decreasing and at the same time is increased fuel spraying dispersion.


AVS unit was created as a reactor for large industrial productivity. This ultrasonic generator can be successfully used for:


·        petroleum treatment for pipeline transportation which leads to petroleum viscosity decreasing, destruction of paraffin leads to reduction of the sedimentation on pipe walls;

·        pre-cracking petroleum treatment for the purpose of light fraction yield increase.


Experimental Results: Light fuel product yield increasing


Experimental researches show the following results:

- cavitational treatment allows increasing the fraction yield at the same volatilization temperature.


It follows that ultrasonic vibrations accelerate petroleum diffusion in paraffin, intensify the process of paraffin destruction. Acceleration of paraffin dissolution is caused by intensification of oil blending process (on the line oil-paraffin) and influence of pressure surge.
