Plate Pack Coalescer
(for liquid-liquid and three-phase separators)
Plate pack thin layer coalescers (interceptors) are used to separate emulsions with droplet diameter above 30 μm.
Plate pack is a pack of thin parallel flat or wavy plates installed at equal distances. When the flow moves through thin passages between plates, droplets sit on plates thanks to gravity forces. Globules leave plates via gutters. Plates are inclined (usually 45° or 60°). Distance between plates varies around 15…60 mm (lower figures for cleaner liquids, higher figures for contaminated liquids).
