<p>A desalter/dehydrater having a plurality of electrified coalescing stages in a single vessel wherein the stages are isolated hydraulically to allow parallel or serial stage operation and the emulsion being treated is introduced at one side of the vessel and caused to flow to the opposite side between horizontal planar permeable electrodes. In one embodiment, several electrical stages are operated in parallel to increase vessel throuqhput capacity. In another embodiment, series operation is employed, wherein each successive stage receives the product from the preceding stage as feed with fresh water being added. The number of stages is one less than the number of the electrodes.</p> |
