Abstract
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.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
144 words
Apparatus for separating components of different densities in a fluid mixture or emulsion comprising: a container; inlet means at one end of said container for introducing said mixture at various levels within said container to minimize turbulence in said container; first discharge means at the other end of said container for removing the more dense component at various levels below the level of the less dense component; second discharge means at said other end of said container for removing the less dense component at a level above the top level of the more dense component; at least one stack of horizontally disposed spaced plates having alternating crests and valleys forming alternately constricting and expanding passages normal to the flow of the mixture between said inlet means and said discharge means; and said spaced plates having spaced bleed holes at the peaks of the crests.
