Free excess charge which is net unipolar is introduced, preferably by charge injection, into the continuous phase. The charge transfers, through the continuous phase, to the dispersed phase and an induced electric field is thereby set up which drives the charged dispersed phase to one or more collector surfaces in contact with the continuous phase. According to different applications, the collector surfaces can take the form of the inside surface of a separation vessel (6) and/or beads (33) of low conductivity or porous material (24). An important application is to the dewaxing and dewatering of lube oil. |
