Abstract
Abstract An improved apparatus for separating entrained liquid from a stream of gas by sequentially subjecting the stream to centrifugal action in first one direction and then in a second opposite direction, and the entrained liquid collecting on multiple screens as a result thereof. The separated liquid drains downwardly on the screen by gravity to a quiescent zone where it is free to flow to a settling tank, with the liquid after entering the tank stratifying into layers of oil and water that may be selectively removed from the tank by first and second valve outlets. The separated liquid when in the quiescent zone is substantially free from the action of the flowing stream as the latter flows through first and second annulus shaped spaces. The gas substantially free from entrained liquid flows upwardly from the apparatus to a desired destination.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
76 words
An apparatus as defined in claim 1 in which said third means comprise: h. first and second rigid arcuate substantially horizontal plates that extend transversely between said first and second screEns and said third and fourth screens at an elevated position above said bottom plate; and i. fourth means for rigidly supporting said first and second arcuate plates above said lower plate, said arcuate plates and said lower plate cooperating to define said quiescent zone therebetween.
Claim 2
Dependent Claim
42 words
An apparatus as defined in claim 2 in which said fourth means are a plurality of circumferentially spaced vertical pedestals that extend upwardly from said lower plate and are secured on the upper ends thereof to said first and second arcuate plates.
Claim 3
Dependent Claim
79 words
An apparatus as defined in claim 3 in which said third opening is formed in said lower plate between said inner shell and said intermediately positioned shell, and said intermediately positioned shell has a fourth opening in the lower portion thereof to permit liquid collecting on said lower plate between said intermediately positioned shell and said outer shell to flow through said fourth opening to said third opening and then drop downwardly due to gravity into said settling tank.
Claim 4
Independent Claim
247 words
A method of separating an entrained liquid that may contain both water and oil from a stream of gas that comprises the steps of: a. directing said stream with said entrained liquid into said first annulus shaped space to flow in a first direction therein to subject said entrained liquid to a first centrifugal force to separate said liquid from said gas; b. directing said stream of gas and liquid remaining entrained therewith after it has traversed said first annulus shaped space into a second annulus shaped space where said gas and remaining entrained liquid travel in a second direction opposite said first direction to be subjected to a second centrifugal force to separate the remaining entrained liquid from said gas; c. allowing said gas free of said entrained liquid to escape from said second annulus shaped space; d. allowing said entrained liquid that separates from said stream of gas in said first and second annulus shaped spaces to flow downwardly therein by gravity to a quiescent zone where said liquid is not subjected to the action of said gas as the latter flows through said first and second annulus shaped spaces; e. removing said liquid as it collects in said quiescent zone and directing said liquid into a confined space; f. allowing said liquid to stratify into layers of oil and water in said confined space; and g. separating said layers of oil and water from one another after they have accumulated in said confined space.
