Abstract

A device in connection with a pipe separator, comprising an extended tubular body (1) with a diameter that is principally the same as or slightly larger than the diameter of the inlet pipe (3)/outlet pipe of the separator.

A separate gas manifold (2) is arranged in connection with the inlet. The manifold (2) comprises a number of vertical degassing pipes (7), which are connected to the inlet pipe (3) immediately ahead of the inlet to the separator and which end in an overlying, preferably slightly inclined gas collection pipe (6). The gas is designed to be diverted up through the vertical degassing pipes and collected in the gas collection pipe (6) for return to the outlet pipe after the separator or transport onwards to a gas tank or gas processing plant or similar.

Claims

1. A device in connection with a pipe separator, comprising an extended tubular body (1) with a diameter that is principally the same as or slightly larger than the diameter of the inlet pipe (3)/outlet pipe of the separator,

characterised in that

a separate gas manifold (2) is arranged in connection with the inlet;

the manifold (2) comprises a number of vertical degassing pipes (7), which are connected to the inlet pipe (3) immediately ahead of the inlet to the separator and end in an overlying, preferably slightly inclined gas collection pipe (6);

the gas is designed to be diverted up through the vertical degassing pipes and collected in the gas collection pipe (6) for return to the outlet pipe after the separator or transport onwards to a gas tank or gas processing plant.

2. A device in accordance with claim 1,

characterised in that

the supply pipe (3) with the gas manifold (2) is raised to a level (in the area 9) above the pipe separator (1).

3. A device in accordance with claim 1,

characterised in that

the diameter of the transport pipe at the inlet to the separator, under the last of the degassing pipes (7) of the manifold (in the area 8), has an extended diameter, for example equivalent to the diameter of the pipe separator (2).
