[0033] The strongly whirling flow, formed in device 2 (
[0034] At the point of the internal and external flows' separation, shear axial velocities generate an intensive anisotropic turbulence, prevailing in the radial direction, in the field with a high radial pressure gradient.
[0035] Turbulent moles, moving in the radial direction, generate high frequency pressure fluctuations, intensify cavitation effects, lead to heating the flows, facilitate the formation of oxygen and hydrogen ions.
[0036] The radial pressure gradient in vortex chamber leads to a density separation of oxygen, hydrogen ions along with other flow elements. Hydrogen ions move into internal flow, and oxygen ions move into external flow, increasing the rate of exothermic chemical synthesis reactions.
[0037] The flows' rising temperature increases the water dissociation degree that obtains the properties of a solvent, reagent, catalytic agent, which, combined with catalytic agents on the inner surfaces of vortex chamber and of outlet nozzle, results in an increase of the rates and expansion of the types of exothermic chemical synthesis reactions.

All this facilitates an increase of the efficiency of the proposed method of implementation of the operational process of hydrocarbon substances' processing as well as of the design of the device for its implementation.

[0045] The use of an electrolyte as a liquid component of the mixture to be processed expands the area of application of the method and the device according to the type of the substance to be processed, improves the environmental characteristics due to processing and disposal of hydrocarbon-containing industrial waste (for example, oil slimes). All this facilitates an increase of the efficiency of the proposed method of implementation of the operational process of hydrocarbon substances' processing as well as of the design of the device for its implementation.
[0046] In vortex chamber 1 (
[0047] From external switching device to the coils of conductors 20 (
[0048] By changing frequency and direction of electric current, a high frequency alternating electromagnetic field is formed inside vortex chamber, which creates a broadband resonance amplification of its own frequencies in the flows, including the frequencies of the radial fluctuations of charged turbulent moles, dissociated and ionized molecules, vibrations of collapsed cavitation bubbles and others.
[0049] In vortex chamber there takes place an intensification of heating processes, heat-mass exchange processes, formation of active charged particles, increase of the rates of the chemical reactions of liquid and gaseous hydrocarbon products synthesis processes.
[0050] The proposed method is implemented as follows. It is prepared a fluid mixture, for example, water or electrolyte with a substance milled to dust, which is fed into one or more blocks for primary processing of mixture 21 (
[0051] Within the flow there are provided high voltage, short-pulse electric current discharges of variable frequency, generated by external switching device.
[0052] The discharges are distributed both along the length and along the circumference of axisymmetric flow, as well as jointly along the length and along the circumference. The number of discharges depends on the device's productivity as well as on the type of the substances to be processed.
[0053] In addition to these discharges, high voltage, short-pulse electric current discharges of variable frequency, that are placed along the radius of axisymmetric flow, between a pair of or several pairs of electrodes 27 and 28 (
[0054] Depending on the substance to be processed, the area of parallel radial discharges is supplied with either air or hydrogen or methane-containing gas or other gas, which is formed as axial streams directed towards each other, and which is fed into an axial clearance, forming in it a gas saturated area, wherein discharges are carried out.
[0055] The use of short-pulse electrical discharges results in a strong mechanical compression, generation of powerful ultrasound, x-ray, ultra-violet and infrared radiations in the areas of discharge, which induce thermal and shock effects, electromagnetic fields, ionization, dissociative, cavitation as well as physical and chemical effects.
[0056] Supply of a gas fraction to the discharge area intensifies cavitation, initiates exothermic reactions of higher hydrocarbons' synthesis, reduces the required operating discharge voltage.
[0057] The formed axisymmetric mixture flow, which includes a gas fraction, dissociated and ionized components, is accelerated.
[0058] Thus, the implementation of primary electro-hydrodynamic mixture processing within the proposed method leads to an increase of productivity for the substance to be processed, improvement of environmental performance due to the lack of environmental emissions, enhancement of economic performance by increasing the liquid derivative products, as well as to an expansion of the types of the substances to be processed.
[0059] The formed axisymmetric mixture flow is fed into tangential nozzle swirling device 2 (
[0060] Thus, the formation, within the proposed method, of a strongly whirling high-speed three-phase flow, containing cavitation, dissociated and ionized components, results in a possibility of carrying out the main phase of the electro-hydrodynamic mixture processing in vortex chamber, where the implementation of the operational process facilitates an increase of the efficiency of the proposed method of hydrocarbon substances' processing.
[0061] The strongly whirling flow, formed in device 2 (
[0062] External flow is directed away from tangential nozzle swirling device 2 (
[0063] At the point of internal and external flows' separation, shear axial velocities generate an intensive anisotropic turbulence, prevailing in the radial direction, in the field with a high radial pressure gradient.
[0064] Turbulent moles, moving in the radial direction, generate high frequency pressure fluctuations, intensify cavitation effects, lead to heating the flows, facilitate the formation of oxygen and hydrogen ions.
[0065] The radial pressure gradient in vortex chamber leads to a density separation of oxygen, hydrogen ions along with other flow elements; in this case hydrogen ions move to internal flow, and oxygen ions move to external flow, causing exothermic chemical synthesis reactions.
[0066] The flows' rising temperature increases the water dissociation degree that obtains the properties of a solvent, reagent, catalytic agent, which, combined with catalytic agents on the inner surfaces of vortex chamber and of outlet nozzle, results in an increase of the rates and expansion of the types of exothermic chemical synthesis reactions.
[0067] Heating of the flow results in formation at the separation point of external and internal flows of a water-steam phase transfer, with steam condensation in external flow, which leads to its additional heating, growth of pressure, achieving the water boiling point, to an increase of the dissociation degree at the separation point, to creation of a static difference of electric field potentials. These effects facilitate the increase of the rates and expansion of the types of exothermic chemical synthesis reactions.
[0068] The increase of the rates of exothermic chemical synthesis reactions is facilitated by the use as catalytic agents in external flow such catalytic agents, that contain zinc, chromium, group VIII metals of the Periodic system of chemical elements and ZSM type zeolites with metal salts, and at the outlet of internal flowcatalytic agents containing carbides, nitrides, borides and oxides of group IV metals of the Periodic system of chemical elements.
[0069] Thus, the processes implemented in vortex chamber through the proposed method facilitates an increase of the efficiency of the proposed method of implementation of the operational process of hydrocarbon substances' processing as well as of the design of the device for its implementation.
[0070] External flow is moved to the opposite from the swirling device end of vortex chamber 1 (
[0071] Alternating electric current is fed from external switching device to electrodes 15 and 17 (
[0072] Heating of water results in an increase of the dissociation degree. Water obtains the properties of a solvent, reagent, catalytic agent, which facilitates an increase of the rate of exothermic synthesis reactions, which results in an increase of the substance processing productivity.
[0073] In inner volume 7 of block 6 (
[0074] The more dense flow components are withdrawn through fitting 5 (
[0075] The use of an electrolyte as a mixture's liquid component expands the area of application of the method according to the type of the substance to be processed, improves the environmental characteristics due to processing and disposal of hydrocarbon-containing industrial waste (for example, oil slimes).
[0076] All this facilitates an increase of the efficiency of implementing the operational process in the vortex chamber and, consequently, of the entire process as a whole.
[0077] The flows, formed in vortex chamber 1 (
[0078] By changing frequency and direction of electric current, a high frequency alternating electromagnetic field is formed inside vortex chamber, which creates in the flows a broadband resonance amplification of its own frequencies, including the frequencies of the radial fluctuations of charged turbulent moles, dissociated and ionized molecules, vibrations of collapsed cavitation bubbles and others.
[0079] In vortex chamber there takes place an intensification of heating processes, heat-mass exchange processes, formation of active charged particles, increase of the rates of the chemical reactions of liquid and gaseous hydrocarbon products synthesis processes.
[0080] Implementation of the method of exposing the prepared flow to an electromagnetic effect in vortex chamber, with formation of broadband resonance amplification of its own frequencies, results in an intensification of physical and chemical processes, and thus in an increase of the efficiency of implementing the operational process of hydrocarbon substances' processing in vortex chamber and, consequently, of the entire process as a whole.
[0081] Electro-hydrodynamic treatment is being performed by way of complementary feeding thus processed mixture with argon from an external source.
[0082] Conducting such a treatment with a complementary introduction of argon intensifies the process of breaking down long molecules in worked-on hydrocarbons, for example finely crushed polyethylene, which in turn expands application field for the described method.
[0083] Implementation of the method, and its realization in the device, of exposing the prepared flow to an electromagnetic effect in vortex chamber, with formation of broadband resonance amplification of its own frequencies, results in an intensification of physical and chemical processes, and thus in an increase of the efficiency of implementing the operational process of hydrocarbon substances' processing in vortex chamber.
