Problems solved by technology

However, the onset of phase inversion and its course cannot be precisely controlled
This means that it is impossible to predict when and where the phase inversion will occur downstream of the valve

Embodiment Construction

[0058] figure 1 A schematic flow diagram is shown of a phase inversion system according to the prior art incorporating a valve according to the method of WO2005 / 005776. A system 101 for phase inversion of a two-phase dispersion of oil and water comprises a first fluid 102, which is water, forming a dispersed phase, and a second fluid 103, which is an oil, which forms a continuous Mutually. Fluid supply means 104 for supplying water 102 and oil 103 to the valve 105 can be foreseen. Valve 105 introduces high shear forces into the oil and water phases, resulting in smaller droplets. The shear force acts on the surface of the droplet. One of the results of this is that the surfactant present on the droplet surface is carried away from the droplet surface. Surfactants are considered to have a stabilizing effect on the droplet, meaning that the droplet itself remains stable as long as the surfactant is present on the droplet surface. Consequently, the dispersion also remains st...

Abstract

A method and system for phase inversion of a dispersion comprising a first fluid forming a dispersed phase and a second fluid forming a continuous phase are disclosed. The dispersion is supplied to the phase inversion device in the fluid supply means. Thereby, the first fluid is transformed from the dispersed phase to the continuous phase and the second fluid is transformed from the continuous phase to the dispersed phase. The phase inversion device includes elements providing fluid contact surfaces for coalescence in the direction of flow.

Description

technical field [0001] The invention relates to a method, in particular for phase inversion of dispersions, and a system for carrying out said method. In the case of a dispersion, a mixture of immiscible fluids is contemplated, comprising a first fluid forming a dispersed phase and a second fluid forming a continuous phase. In the case of phase inversion, a process step is contemplated in which a first fluid is transformed from a dispersed phase to a continuous phase or a combination of a continuous and dispersed phase and a second fluid is transformed from a continuous phase to a dispersed or continuous phase Combination with dispersed phase. A possible field of use for such phase inversion methods and systems is oil-water separation. Background technique [0002] In WO 2005 / 005776 it is disclosed that phase inversion is used to improve oil-water separation and in connection with the extraction of such fluids from rock formations on the earth's surface or beneath the seaf...
