Abstract
Abstract Method and device for treating a gas/liquid mixture, the device comprising: an inlet for infeed of the mixture; a flow element placed in the line of the inlet and having one or more swirling members to cause turbulence of the mixture; an outlet placed in the line of the flow element for outfeed of the gas flow having liquid at least partially removed; one or more feedback lines for discharge of the separated liquid and a part of the gas flow, wherein the feedback lines are connected onto a channel arranged centrally in the flow element; and anti-creep flow means for preventing creep flow along the flow element.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
180 words
A device for treating a gas/liquid mixture, comprising: a. a substantially cylindrical wall defining a flow space having an upstream end and a downstream end and having one or more openings adjacent to the downstream end; b. an inlet for infeed of the mixture at the upstream end of said wall; c. a flow element placed downstream relative to said inlet and upstream relative to the openings in said wall, having a channel arranged centrally therein, said flow element having one or more swirling members to cause turbulence of the mixture; d. an outlet in said wall downstream of said flow element for outfeed of the gas flow having liquid at least partially removed; e. one or more feedback lines fluidly connected to the openings in said wall for discharge of liquid and part of the gas flow separated from the gas/liquid mixture through the openings, wherein said feedback lines are fluidly connected to an upstream end of said channel; and f. an anti-creep flow element extending from a downstream end of the flow element and arranged about the channel.
Claim 2
Independent Claim
180 words
A device for treating a gas/liquid mixture, comprising: a. a substantially cylindrical wall defining a flow space having an upstream end and a downstream end and having one or more openings adjacent to the downstream end; b. an inlet for infeed of the mixture at the upstream end of said wall; c. a flow element placed downstream relative to said inlet and upstream relative to the openings in said wall, having a channel arranged centrally therein, said flow element having one or more swirling members to cause turbulence of the mixture; d. an outlet in said wall downstream of said flow element for outfeed of the gas flow having liquid at least partially removed; e. one or more feedback lines fluidly connected to the openings in said wall for discharge of liquid and part of the gas flow separated from the gas/liquid mixture through the openings, wherein said feedback lines are fluidly connected to an upstream end of said channel; and f. an anti-creep flow element extending from a downstream end of the flow element and arranged about the channel.
Claim 3
Dependent Claim
19 words
The device as claimed in claim 1 , wherein the anti-creep flow element extends downstream from said flow element.
Claim 4
Dependent Claim
28 words
The device as claimed in claim 1 , wherein the anti-creep flow element extends radially at least some distance outwards relative to the channel and toward said wall.
Claim 5
Dependent Claim
18 words
The device as claimed in claim 1 , wherein the anti-creep flow element has a truncated cone shape.
Claim 6
Dependent Claim
18 words
The device as claimed in claim 1 , wherein the anti-creep flow element is at least partly disc-shaped.
Claim 7
Dependent Claim
19 words
The device as claimed in claim 1 , wherein the swirling members comprise swirling blades curved in flow direction.
Claim 8
Dependent Claim
18 words
The device as claimed in claim 1 , wherein about 2-20% of the gas flow is fed back.
Claim 9
Dependent Claim
20 words
The device as claimed in claim 1 , wherein the internal diameter of the channel is at least 2 mm.
Claim 10
Dependent Claim
36 words
A method for treating a gas/liquid mixture, comprising the steps of: a. providing a device as claimed in claim 1 , and b. feeding a mixture of gas and liquid through the inlet of the device.
Claim 11
Dependent Claim
64 words
A system for treating a gas/liquid mixture from a bored well in the earth's crust, comprising: a. an outer pipeline which can be lowered into a bored well; b. an inner pipeline within the outer pipeline suitably arranged to form a radial space; and c. a plurality of gas/liquid separating devices as claimed in claim 1 , arranged in parallel within the radial space.
