Abstract: A centrifugal method and apparatus capable of separating a fluid stream composed of a plurality of components with differing specific gravities. The stream contemplated for separation is that of a producing oil well with components of oil, water, natural gas, and particulates. The method and apparatus use centrifugal forces to separate the gaseous, solid, and liquid components from each other. After separation is completed, detector and sensor arrangements are used to maintain liquid levels in the separator and to control the removal of the individual separated fluids from the apparatus.

Abstract: The present invention is a centrifuge method and apparatus for separating the components of a stream, particularly a wellstream. Centrifugal force is used to separate solid and liquid components from gaseous components, and the combined action of centrifugal force and countercurrent flow is used to separate a first liquid, such as crude oil, from a second liquid, such as water. In addition, the combined action of centrifugal force and countercurrent flow can be used to separate a heavy gas, such as carbon dioxide, from a light gas, such as hydrocarbon gas.
