Manifold flow splitter

1. A manifold for use in a flow system, comprising:

a longitudinal main pipe section with one inlet connectable to a feed pipe and at least two outlets arranged in a row along the main pipe section, a centre axis of the main pipe section during normal use extending in a mainly horizontal direction;

wherein each outlet is arranged in a lower half of the main pipe section and is connected to a corresponding outlet pipe section having a centre axis extending at a downward angle from the main pipe section; and

wherein all of the outlets are arranged, when seen in a cross section of the main pipe section, with the centre axis of each of the outlet pipe sections in separate planes perpendicular to the centre axis of the main pipe section and forming an identical angle θ of between 35 degrees and 50 degrees in relation to a vertical axis.

2. The manifold according to claim 1 , wherein the angle θ is 45 degrees in relation to the vertical axis.

3. The manifold according to claim 1 , wherein the outlet pipe sections are connected to the main pipe section such that the centre axes of the outlet pipes sections cross the centre axis of the main pipe section.

4. The manifold according to claim 1 , wherein two rows of outlets are arranged in the lower half of the main pipe section.

5. The manifold according to claim 4 , wherein an outlet in one row is arranged in the same transverse plane as an outlet in the other row.

6. The manifold according to claim 1 , wherein the inlet is arranged at one end of the main pipe section.

7. A method for distributing a mixed flow into several pipes, comprising: leading the mixed flow into a horizontal pipe where a liquid phase of the mixed flow positions itself in a lower cross section of the pipe and a gas phase of the mixed flow positions itself in the rest of the cross section of the pipe, then removing a mixture of the liquid phase and the gas phase out of the pipe through at least two outlet pipe sections which are each connected to a corresponding outlet in a lower part of the pipe, each outlet pipe section comprising a respective centre axis and being arranged, when seen in a cross section of the horizontal pipe, with the centre axis of the outlet pipe section in a separate plane which is perpendicular to the centre axis of the horizontal pipe and at an identical angle θ of 30 degrees to 50 degrees with respect to a vertical axis; wherein the liquid phase is removed from the pipe through a lower part of the cross section of each outlet and the gas phase is removed from the pipe through the rest of the cross section of each outlet.

8. The method according to claim 7 , wherein the angle θ is 45 degrees with respect to the vertical axis.

9. A method for cooling a multiphase fluid, comprising:

leading the multiphase fluid into a manifold and thereby splitting the fluid into several multiphase flow fractions; then

cooling each of the flow fractions separately; and then

combining the flow fractions into a common multiphase flow;

wherein the manifold comprises a longitudinal main pipe section having one inlet connectable to a feed pipe and at least two outlets arranged in a row along the main pipe section, a centre axis of the main pipe section during normal use extending in a mainly horizontal direction, each outlet being arranged in a lower half of the main pipe section and being connected to a corresponding outlet pipe section having a centre axis which extends, when viewed in a cross section of the main pipe section, at an angle θ of between 35 degrees and 50 degrees in relation to a vertical axis; and

wherein, when seen in a cross section of the main pipe section, the centre axis of each outlet pipe section is positioned in a separate plane which is perpendicular to the centre axis of the main pipe section.
