Abstract: The coalescing plate is designed to separate immiscible components of differing densities mixed in a fluid. The plate includes bidirectional corrugations forming crests and valleys. Bleed holes are provided in the crests and valleys to allow the immiscible components to pass through. Plural plates are stacked and separated by spacers. The spacers are configured to provide multiple spacings between adjacent plates. The immiscible components less dense than the host fluid migrate upwardly and pass through the bleed holes in the crests. Solids and other components denser than the host fluid move downwardly and pass through the bleed holes in the valleys. The plates are readily cleaned in situ by passing a nozzle through the bleed holes nad introducing a pressurized fluid or gas to flush out the space between the plates.

Abstract: The plates in a plate type separator have a corrugated configuration and are stacked with the corrugations parallel to each other and normal to the flow of the mixture to be separated. The corrugations on each plate are shaped and positioned relative to those on adjacent plates to provide alternatively constricting and expanding fluid passages. Accelerations and decelerations are thereby imparted to the mixture. Dispersed drops of different sizes will acquire different accelerations and decelerations, enhancing collisions between drops and coalescense of them.
