Abstract
Abstract A diagrammatic representation of a single tube is housed to form a gravity separation chamber for the liquid separated from gas by the tube, and the tube is shown to be in several axially aligned sections spaced from each other to provide the exits and reentry paths between the tube and chamber for the separating fluids.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
151 words
For use in a liquid-gas separator, a vortex tube assembly for processing gas which is mixed with entrained liquid in drops of 5 micron and larger, including, an inlet section of pipe closed at the extreme end and having a length of 6D and adapted to receive the mixture, a vortex pipe axially aligned with the inlet section of pipe and spaced from the inlet section to define a gap and having a length of 10D, an outlet pipe axially aligned with the inlet and vortex pipe and spaced from the vortex pipe to define a gap, a plurality of nozzles mounted on the inlet section of pipe to receive the gas and entrained liquid and direct the fluid mixture tangent to the internal diameter of the pipe, and an ejector nozzle on the exit end of the inlet section of pipe formed by reducing the cross section of the pipe.
Claim 2
Dependent Claim
151 words
For use in a liquid-gas separator, a vortex tube assembly for processing gas which is mixed with entrained liquid in drops of 5 micron and larger, including, an inlet section of pipe closed at the extreme end and having a length of 6D and adapted to receive the mixture, a vortex pipe axially aligned with the inlet section of pipe and spaced from the inlet section to define a gap and having a length of 10D, an outlet pipe axially aligned with the inlet and vortex pipe and spaced from the vortex pipe to define a gap, a plurality of nozzles mounted on the inlet section of pipe to receive the gas and entrained liquid and direct the fluid mixture tangent to the internal diameter of the pipe, and an ejector nozzle on the exit end of the inlet section of pipe formed by reducing the cross section of the pipe.
Claim 3
Dependent Claim
93 words
The vortex tube of claim 1 in which, the inlet section and vortex pipe and outlet pipe have a 3 inch standard pipe diameter, three nozzles are mounted on the inlet section of pipe and each have a width of no less than 0.5 inches and not more than 0.65 inches and a total area of 5 square inches, and the ejector nozzle is formed by reducing the 3 inch diameter pipe to 2 inches to 21/4 inches diameter and is spaced 1/2 inch from the opening of the axially aligned vortex pipe.
Claim 4
Dependent Claim
33 words
The vortex tube of claim 2, of which the vortex pipe comprises, a bulk liquid section 2D in length, and a downstream section 8D in length with the separator used in vertical operation.
Claim 5
Dependent Claim
31 words
The vortex tube of claim 2, of which the vortex pipe comprises, a bulk liquid section 2D in length, and a downstream section 15D with the separator used in horizontal operation.
Claim 6
Dependent Claim
28 words
The vortex tube of claim 1 in which, the outlet pipe is fixed in axial alignment with the vortex pipe and spaced 1/8 inch from the vortex pipe.
Claim 7
Dependent Claim
34 words
The vortex tube of claim 3 in which, the bulk liquid section of the vortex pipe is spaced within a range of 3/32 inch to 1/8 inch from the remainder of the vortex pipe.
