Definitions

  • Forming the object of the present finding is a process for the separation of two-phase fluids and the relative accelerator unit.
  • different systems for separating two-phase fluids are known, which are based upon the following principles, used totally or in part, according to the type of unit: the principle of coalescence that indeed induces the phenomenon of coalescence in the particles of dispersed fluid, through coalescing filters or fluid channelling arrays; the principle of separation that induces a laminar flow in the two-phase fluid in order to cancel out the force vectors of a turbulent flow, as well as a natural physical separation of the two fluids, with speed proportional to their difference in density; finally, the principle of removal of the dispersed fluid that separates the fluid at lower density through use of skimmers or by overflow, still in laminar flow.
  • the great disadvantage of known systems consists of the fact that none of them is able to accelerate the separation process of the two-phase fluid.
  • the above systems have all great limitations linked to the following negative aspects:
  • the latter comprises pumping means (o forse il pi ⁇ letterale thrusting means, non Pato dal contesto, ndt) of the two-phase fluid, at least one washing tank, filtering means for the coalescence of the particles, sensors and actuators for controlling flow rate, pressure and temperature, at least one tank for collecting the fluid at a lower density (normally oil) and is characterised by an oil separator capable of generating a controlled field of hydrodynamic pressures, correlated to the density of the fluids to be treated, in order to accelerate the phenomenon of coalescence of the residual particles.
  • a field of pressures accelerates the stratification phenomenon, allowing the phase at lower density (for example oil) to be drawn off and the constant flow of the decontaminated phase (for example water) towards the outlet from the system.
  • the purpose of the finding is therefore to achieve the task of accelerating the separation of two fluids that cannot be mixed, at different density, in turbulent flow. According to a further purpose, the finding is reversible, since it allows the separation of the dispersed phase, without limitations in concentration in the continuous phase.
  • the unit in object comprises a first pumping means (1) of the two-phase fluid, at least one washing tank (2), a second pumping means of the fluid (3), filtering means for the coalescence of the particles (4), (5) with different filtering power, a phase separator (6) that constitutes the heart of the system, at least one tank for collecting the fluid at lower density (7), a system for analysing the decontamination of the residual phase (8), sensors and actuators for controlling flow rate, pressure and temperature.
  • the two-phase fluid to be separated is therefore given the mechanical energy necessary to equalise the pressure drops of the system from the pumping means (1), (3).
  • a first phenomenon of size variation of the particles is induced through forced coalescence in the filtering batteries (4), (5), in order to make the separation process easier.
  • the hydrostatic thrust acting on the particles counteracted by the force vectors induced by the Brownian motion generated by the turbulence of the fluid, allows a first separation of the two phases to be obtained.
  • the fluid is then mechanically channelled, through calibrated diffusers, capable of generating a laminar flow and simultaneously the stratification of the two phases.
  • a controlled field of hydrodynamic pressures is generated, correlated to the density of the fluids to be treated, in order to accelerate the phenomenon of coalescence of the residual particles.
  • Such a field of pressures accelerates the stratification phenomenon, allowing the phase at lower density (for example oil) to be drawn off towards the collection tank (7) and the constant flow of the decontaminated phase (for example water) towards the outlet from the system.
  • the analysis of the decontamination is possible in the system (8) and normally the level of residual pollutant is of the order of a few ppm.
  • the two-phase fluid separation accelerator is therefore the ideal system for the separation of two fluids at different density, in a vast field of application and without restrictions of any sort concerning the fluids, the flow rates, the temperatures, the flow and the characteristics of the location of use. It is recommended for applications in the following fields: mechanics, ironworking, oil, food, shipping, aeronautics, environmental protection, maritime ecology and chemistry.

Abstract

La présente invention concerne un procédé de séparation de fluides biphasés et unité d'accélérateur associée, comportant un moyen de pompage de fluide biphasé, au moins une cuve de lavage, un moyen de filtration pour la coalescence des particules, des capteurs et des actionneurs pour contrôler le débit, la pression et la température, au moins un réservoir pour recueillir le fluide à faible densité (normalement de l'huile) et est caractérisée par un séparateur d'huile dans lequel un champ contrôlé des pressions hydrodynamiques est généré, corrélé à la densité des fluides à traiter, qui accélère le phénomène de stratification, permettant le prélèvement de la phase à faible densité (par exemple, de l'huile) et l'écoulement constant de la phase décontaminée (par exemple, de l'eau) vers l'orifice de sortie hors du système.
