- a plant for the production of a stable hydrocarbon-water fine dispersion or a water-hydrocarbon separating dispersion (a water-hydrocarbon dispersion easily separable into at least two phases, or unstable separating dispersion) is provided, the plant having at least one unit to produce a hydrocarbon-water dispersion in the fine disperser from at least medium 1 as a hydrocarbon-containing medium and medium 2 as water (deionized water) and this unit has at least one premixer (coarse disperser), at least one first pump, for increasing pressure in the feed of the hydrocarbon-water mixture into the ultrasonic acoustic flow unit (UADA as part of the fine disperser); at least one ultrasonic acoustic flow unit (UADA) for the production of a hydrocarbon-water fine dispersion by means of hydrodynamic cavitation and at least one second pump for generating a negative pressure behind the UADA, or at least one unit for producing an unstable water-hydro

- the present system thus comprises in a third aspect a combination of a coarse disperser, a fine disperser and a downstream ultrafine disperser.
- the object of the present invention is also achieved with a method having the features of claim 6, FIG. 2.
- the basis of the present system and the process is the principle of cavitation. Cavitation is the formation and implosive dissolution of vapor bubbles in liquids.
- the UADA is used to produce a hydrocarbon-water dispersion by means of cavitation.
- the principle of dispersion generation using the system according to the invention is based on the fact that a mixture of at least two different media is pressed through special nozzles in a UADA.
- the at least two different media are premixed with one another.
- the further steps in the production of a hydrocarbon-water dispersion by means of cavitation take place in at least one or two UADA modules.
- a first UADA module supercavitation, as an individual case of hydrodynamic cavitation, takes place in the other, second UADA module, thermal and supercavitation.
- the two UADA modules are connected one behind the other.
- the size of the water droplets in the dispersion is varied by the type and intensity of the cavitation. Stronger cavitations result in a smaller diameter of the enclosed drop.
- the present process enables the production of a hydrocarbon-water dispersion with a droplet size in the range from 10 to 100 ⁇ m. The stability of the dispersion increases with decreasing droplet diameter.
- the droplet size in the dispersion is regulated by varying degrees of cavitation.
- the droplet size, phase distribution and morphology in turn have an influence on the stability of the dispersion.
- the cavitation is set, varied and controlled.
- the droplet size, phase division and morphology have an influence on the stability (quality) of the dispersion.
- the cavitation is set, varied and controlled.
- the droplet size in the dispersion is regulated by varying degrees of cavitation. For the quality of the hydrocarbon-water dispersion to be produced with the present system, it is important to set the optimal intensity of the cavitation.
- Droplet diameter in the coarse dispersion larger than 1 mm.
- Droplet diameter in the fine dispersion smaller than 1 mm and larger than 100 ⁇ m
- the present system makes it possible to keep the water content and the process parameters pressure, temperature and throughput constant in order to ensure a constant quality of the water-oil dispersion produced.
- the developed process can be built up in two or three procedural stages. On the one hand, there is a technological implementation of coarse and fine dispersion. The other technological solution for deeper dispersion consists of coarse, fine and ultra dispersion.
- a coarse dispersion of the pre-tempered medium 1 as a hydrocarbon-containing medium and the pre-tempered medium 2 as water is provided by mixing medium 1 and medium 2 in at least one pre-mixing unit (coarse disperser) before the fine dispersion is made (claim 13).
- a method for producing a hydrocarbon-water dispersion (fine dispersion), or a water-hydrocarbon dispersion (separating dispersion) that can easily be separated into at least two phases is provided, the method being carried out in particular in a plant described above and comprising the following steps :
- UADA ultrasonic acoustic flow unit
- a pressure is set in front of the UADA module (pre-pressure) and a pressure behind the UADA (claim 11).
- the pre-sonic velocity is a transversal deformation of currents through the formation of vortex-ring currents. In the range of the speed of sound, the resulting flow becomes so great that cavitation occurs. Furthermore, long-chain entangled hydrocarbons are torn apart thermomechanically. The inflow is accelerated tangentially in the radial direction, in which the chamber flows are sheared against one another and the relative speed is thus doubled. The high speed creates the vapor bubbles and the displaced eddy currents balance each other out. This creates constant, stable eddies that are separated according to hydrodynamic properties.
- the ultrasonic velocity occurs after the currents meet and the energy of the currents in the confined volume is concentrated. With the help of the concentrated energy, the energy-mass exchange is promoted and the physical-chemical conversion is accelerated. The dispersion formed is discharged from the module through the drain.
- the steam pressure of water must be undercut with the operating pressure by means of hydrostatic pressure and temperature setting (steam pressure curve) by increasing the speed (energy conversion / kinetic pressure component). This results from the vapor pressure curve for water as shown in FIG.
- the type, strength and form of cavitation in the UADA is influenced by the pressure ratio between the pre-pressure and the negative pressure in the fine disperser or in the separating disperser. The more pronounced the cavitation, the smaller the diameter of the droplets in the dispersion,
- the hydrocarbon-water fine dispersion is introduced into at least one further unit for producing an ultrafine dispersion (ultrafine disperser) after leaving the fine disperser, this unit at least one further ultrasonic acoustic flow unit (UADA ) for the production of a hydrocarbon-water ultrafine dispersion by means of a combination of thermodynamic and hydrodynamic cavitation,
- thermocavitation catalyzes the hydrodynamic cavitation in the downstream UADA and thus intensifies the mixing of the dispersion.
- the procedural insert is set up in such a way that there is negative pressure in the meat processing device.
- the procedural insert is set up in such a way that there is negative pressure in the meat processing device.
- thermodynamic and hydrodynamic or super cavitation creates better conditions for producing the ultra-stable and ultra-fine dispersion.
- the type, strength and form of cavitation in the UADA is influenced by the pressure ratio between the pre-pressure and the negative pressure in the ultrafine disperser. The more pronounced the cavitation, the smaller the diameter of the droplets in the dispersion,
- pre-pressure the pressure before the UADA of the ultrafine disperser
- negative pressure the pressure after the UADA of the ultrafine disperser
- the ultrafine dispersion can be achieved technologically either after the coarse dispersion or after the fine dispersion.
- the object of the present invention is also achieved with a method having the features of claims 2 and 5.
- the cavitation process used in the developed system in an ultrasonic acoustic flow unit (UADA) is known from the patents RU 2130503 C1, RU 2462301 C1 and the patent for the useful technical model RU 134076 U1 and enables the production of a stable dispersion Fuel and water.
- this UADA is expanded in combination with heat exchangers and pressure boosting devices, so that the stability of the hydrocarbon-water dispersion formed is significantly increased.
- the heat exchangers installed in the present system allow a separately temperature-controlled hydrocarbon and water supply.
