Abstract:
The present invention relates to a method for the break-up of at least one emulsion and separation of the light and heavy phase with at least an de-emulsification rate of more than 9 % in only one apparatus (module) within less than 5 min by applying at least one time dependent or temporal changeable electrical field wherein the at least one electrical field is a high frequency (HF) singular alternating current (AC) field with an electrical field strength between 2,000 and 100,000 V/m and a frequency (HF) between 12,000 Hz and 200,000 Hz. The present invention relates furthermore to a method for the treatment of at least one emulsion by applying at least one direct current (DC) field and at least one high frequency alternating current -HF/AC field wherein the at least one DC field, in particular a pulsed DC- field, and the at least one HF/AC field are applied in series to the emulsion to be treated. The present invention refers further to a device for conducting said methods.

Abstract:
A system ( 10) for separating the components of an incoming oil-water mixture includes two electrode sets (30/40), one set arranged to apply an electrostatic field to an oil layer residing within a separator vessel and the other set arranged to apply an electrostatic field to the interface emulsion layer residing within the separator vessel (12). The first set of electrodes (30) is in communication with a high voltage power source that ranges from 1 to 60 kV; the second set of electrodes (40) is in communication with a low voltage power source that is no greater than 5 kV. Each set of electrodes (30/40) may also be in communication with a second voltage source to provide increased power to promote effective coalescence. The system (10) may also include power electronics to produce a variable amplitude and a variable frequency voltage supply to one or both electrode sets (30/40).

Abstract:
Systems and methods for subsea fluid phase separation. A two phase embodiment of the subsea fluid separation system separates a multiphase flow into gas and liquid phases. A three phase embodiment of the subsea fluid separation system separates multiphase flow into gas, oil, and water phases. The subsea fluid separation systems include a wellhead desander system to remove solids from the multiphase flow, a vertical gas-liquid separation module having associated valves disposed in series with a horizontal gas-liquid separation module having associated valves, one or more pumps to provide fluid flow to the vertical and horizontal separators, and a control system to control operation of the valves and pumps. The three phase embodiment further includes oil-water separators and multi-stage hydrocyclones for produced water treatment in a subsea environment.
Abstract:
Method and apparatus for separation of dispersed particles from an aqueous dispersion involves subjecting the aqueous dispersion to electrocoagulation (EC) treatment to promote formation of a flocculate comprising the particles, collecting the flocculate comprising the particles as a flocculated layer floating on a clarified aqueous solution and separating the flocculate from the remaining clarified aqueous solution. An aqueous solution of a gas is blended with the aqueous dispersion of particles, prior to separating the flocculate from the remaining clarified aqueous solution, with the aqueous solution arranged to be supersaturated with the gas on blending with the aqueous dispersion. The blending of the EC-treated aqueous dispersion with the supersaturated solution of gas speeds and facilitates separation of flocculate from clarified aqueous solution.
Abstract:
There is a method of facilitating the consolidation of fine tailings through the application of an electrical current. The fine tailings include a combination of at least some water and some clay particles. Electrodes are placed into contact with the fine tailings. An AC voltage with a DC offset is applied to the electrodes to separate water from the clay particles and to induce movement of the separated water to a collection area. The separated clay particles can consolidate more readily than unseparated clay particles. In an embodiment, the fine tailings are mixed fine oil sands extraction tailings which include residual hydrocarbons. In an embodiment, the application of an AC voltage with a DC offset across the electrodes includes applying an AC voltage of about 1 V/cm and a DC offset of about ½ V/cm.
