Abstract
Abstract Apparatus for treating mixtures of liquid and gas comprising a tubular wall (2) defining an inner space (3) and an outer space (6). Swirl imparting means (11) are provided for imparting a rotary movement to a gas/liquid mixture supplied into said inner space to separate the liquid and the gas. In the tubular wall at least one opening (12) is arranged for discharging the separated liquid. A primary gas outlet tube (13) having the lower end (14) thereof positioned inside the inner space (3) is provided for discharging the separated gas stream from the inner space. The apparatus further comprises a secondary gas outlet tube (16) for discharging gas from the outer space (6).

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
193 words
An apparatus for treating mixtures of liquid and gas comprising a tubular wall defining an inner space and an outer space, a top wall arranged at some distance above the tubular wall and confining said inner space and said outer space in upward direction, inlet means for supplying a mixture of a liquid and a gas into the inner space, swirl imparting means inside the inner space for imparting a rotary movement to the mixture of the liquid and the gas to separate the liquid and the gas, outlet means for separately discharging the liquid and the gas from the inner space, said outlet means comprising (a) a primary gas outlet tube, arranged co-axially with the inner space, passing through the top wall and having the lower end thereof positioned inside the inner space below the upper end of the tubular wall, (b) at least one liquid discharge opening arranged in the tubular vail, the apparatus further comprising at least one secondary gas outlet tube for discharging gas from the outer space, said secondary gas outlet tube passing through the top wall and having the lower end thereof positioned inside the outer space.
Claim 2
Independent Claim
193 words
An apparatus for treating mixtures of liquid and gas comprising a tubular wall defining an inner space and an outer space, a top wall arranged at some distance above the tubular wall and confining said inner space and said outer space in upward direction, inlet means for supplying a mixture of a liquid and a gas into the inner space, swirl imparting means inside the inner space for imparting a rotary movement to the mixture of the liquid and the gas to separate the liquid and the gas, outlet means for separately discharging the liquid and the gas from the inner space, said outlet means comprising (a) a primary gas outlet tube, arranged co-axially with the inner space, passing through the top wall and having the lower end thereof positioned inside the inner space below the upper end of the tubular wall, (b) at least one liquid discharge opening arranged in the tubular vail, the apparatus further comprising at least one secondary gas outlet tube for discharging gas from the outer space, said secondary gas outlet tube passing through the top wall and having the lower end thereof positioned inside the outer space.
Claim 3
Dependent Claim
25 words
Apparatus according to claim 1, wherein the lower end of the secondary gas outlet tube is arranged below the upper end of the tubular wall.
Claim 4
Dependent Claim
24 words
The apparatus as claimed in claim 1 or 2, wherein the outer space is at least partly confined in lateral direction by a skirt.
Claim 5
Dependent Claim
21 words
T'ne apparatus as claimed in claim 3, wherein the skirt forms an enveloping wall which is connected to the top wall.
Claim 6
Dependent Claim
25 words
The apparatus as claimed in claim 4, wherein the lower end of the skirt is positioned below the lower end of the liquid discharge opening.
Claim 7
Independent Claim
31 words
The apparatus as claimed in any one of the claims 1-5, wherein the lower end of the primary gas outlet tube extends below the upper end of the liquid discharge opening(s).
Claim 8
Independent Claim
25 words
The apparatus as claimed in any one of the claims 1-6, wherein the apparatus comprises a plurality of substantially equally spaced secondary gas outlet tubes.
Claim 9
Independent Claim
37 words
The apparatus as claimed in any one of the claims 1-7, wherein the cross-sectional area of the secondary gas outlet tube(s) is at least 6 per cent of the cross-sectional area of the primary gas outlet tube.
Claim 10
Independent Claim
37 words
The apparatus as claimed in any one of the claims 1-8, wherein the inlet means are in communication with a mixing chamber for preparing and supplying a mixture of a liquid and gas to the inlet means.
