20100000868 | METHOD FOR FABRICATING A SHEET-SHAPED ELECTRODE AND A SHEET-SHAPED ELECTRODE FOR AN ELECTROSTATIC COALESCING DEVICE - A method for fabricating a sheet-shaped electrode for an electrostatic coalescing device. A layered material structure including an electrically conductive layer for forming a conductive member of the electrode and two electrically non-conductive insulation layers are arranged in an envelope. The insulation layers include thermoplastic or thermoset material for forming the insulation of the electrode. The conductive layer is arranged between the insulation layers. The envelope is sealed. Gas is evacuated from the envelope. The material structure is heated to a temperature above the melting temperature of the thermoplastic material or above the curing temperature of the thermoset material so as to consolidate the material structure while keeping the material structure inside the evacuated envelope. The material structure is cooled and removed from the envelope. | 01-07-2010 |
20100000867 | DEVICE FOR COALESCING FLUIDS - A device for coalescing an emulsion component in an emulsion including a mixture of at least two different fluid components by an electric field applied to the emulsion. The device includes at least one electrostatic coalescer element. The coalescer element includes a tubular channel made of an electrically insulating material, a first electrode mounted on one side of the tubular channel, and a second electrode mounted on the other side of the tubular channel, a first end wall including a first opening adapted to receive a first end of the tubular channel, and a second end wall including a corresponding second opening adapted to receive a second end of the tubular channel. The walls together with the tubular channel isolate the emulsion from the electrodes. | 01-07-2010 |
