Patent ID: 8141718

Claim:
A separation device for the separation of constituents of different density of well fluids from a well, the separation device including: a container having an inner wall; a feed line transporting the fluid into the container, the fluid flowing adjacent the inner wall and at least partially being separated in the container into its constituents using centrifugal force in the radial direction and/or using gravitational force in the vertical direction; a classifier device arranged in a lower section of the container having at least one discharge line extending in the radial direction outwards for the discharge of the fluid adjacent the inner wall of the container and causing the application of a centrifugal force on the fluid and a plurality of delivery lines joined to the container at different levels in the vertical direction to receive the separated fluid constituents; wherein the container is rotationally fixed with respect to the at least one discharge line; wherein the discharge line is in a generally spiral shape at least adjacent to its discharge opening; wherein the classifier device includes a vertical pipe having a plurality of inlets at different vertical levels and in communication with the respective delivery lines; and wherein each one of the plurality of delivery lines extends within the vertical pipe to one of the different vertical levels to receive a separated fluid constituent.
