Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
29 words
The centrifugal separator of claim 1 including discharge turbine means adjacent the end of said drum opposite said inlet means for recovering energy from said separated higher density fluid.
Claim 2
Dependent Claim
65 words
The centrifugal separator of claim 1, wherein said gas removing means comprises a second inner barrel concentrically disposed within said drum with an end opening therein for admission of said gaseous components: an axial discharge outlet in said second barrel for said gaseous components, and a discharge opening in said second barrel for discharging said fluid mixture from said second barrel into said annular space.
Claim 3
Dependent Claim
18 words
The apparatus of claim 3, wherein said gas discharge outlet is concentrically disposed within said feed inlet means.
Claim 4
Dependent Claim
25 words
The apparatus of claim 3, including a pressure regulator on said gas discharge line for controlling the gas-fluid inter-face level within said gas removing means.
Claim 5
Dependent Claim
32 words
The apparatus of claim 3, wherein said discharge opening in said second barrel for the passage of said fluids to said annular space is in the inlet end of said second barrel.
Claim 6
Dependent Claim
26 words
The apparatus of claim 3, wherein said second barrel has side openings therein for passage of said higher and lower density fluids to said annular space.
Claim 7
Dependent Claim
39 words
The apparatus of claim 3, including a multiplicity of longitudinally spaced weirs in said annular space, said weirs having means for passage of said higher density fluid longitudinally through said annular space toward the discharge end of said separator.
Claim 8
Dependent Claim
15 words
The separator of claim 1 including means for recovering solids entraining in said fluid mixture.
Claim 9
Dependent Claim
191 words
A centrifugal separator for treating a fluid mixture having a higher density fluid, a lower density fluid and a gaseous component therein, comprising in combination: a rotable drum having a perforated inner barrel concentrically disposed therein, inlet means for feeding said fluid mixture into said drum near the axis of rotation at one end of said drum, means adjacent said inlet means for receiving gases contained in said mixture into said inner barrel, means for discharging said gaseous component separated from said fluid mixture in said gas receiving means, means for releasing degased fluids from said gas receiving means, impeller means within said drum proximate said inlet means for directing the degased oil-water mixture outwardly into the annular space between said drum and said inner barrel where said higher density fluid separates from said lower density fluid, means at the opposite end of said separator from said inlet means, for recovering said separated higher density fluid from said drum, and said lower density fluid from said inner barrel, and means for isolating said gas receiving means of said inner barrel from said higher density fluid recovering means of said inner barrel.
Claim 10
Independent Claim
185 words
A method for separating a fluid mixture having therein a higher density fluid, a lower density fluid, and a gas, in a separator comprising a rotatable drum having an inner barrel concentrically disposed within said drum, inlet and outlet means at opposite ends of said drum, and a gas separation chamber adjacent said inlet end of said drum, comprising the steps: a. feeding said mixture into said inlet end of said drum so that the gas in said mixture flows into said gas separation chamber to separate from said fluid mixture, b. removing said higher and lower density fluids passing into said chamber with said gas, from said chamber into the annular space between said drum and said barrel after said fluids have separated from said gas in said chamber, c. removing said separated gas from said chamber through gas discharge means, d. controlling the gas-fluid inter-face level in said chamber with a pressure regulator on said gas discharge means, e. separating said degased higher and lower density fluids in said separator, and f. recovering said separated fluids at said discharge end of said drum.
