Abstract

Separation device or unit for separating liquid from an inlet flow which mainly contains gas, has a container or a pipe section with an outlet for gas from the container or the pipe section, an outlet for liquid from the container or pipe section and an inlet for the inlet flow to the container or pipe section. The device has a flow manifold arranged to receive and direct the inlet flow towards a porous pipe body extending towards the gas outlet and arranged to receive all or most of the inlet flow. Part of the flow is flowing through the tubular body to the gas outlet, while the remaining flow is flowing through the tubular body's porous wall, and an annular space including the volume between the tubular body and the container wall or pipe section is open for gas flow towards the gas outlet.

Dependent claims

Separation device for separation of liquid from an inlet flow which mainly comprises gas, wherein the separation device comprises a container or pipe section with an outlet for gas from the container or pipe section, an outlet for liquid from the container or the pipe section, and an inlet for the inlet flow to the container or pipe section, wherein the separation device further comprises:

a flow distributor arranged to receive and put the inlet flow in movement towards a porous tubular body extending towards the gas outlet and arranged to receive all or mainly the whole of the inlet flow, wherein a part of the said flow is flowing through the tubular body to the gas outlet while the remaining of said flow is flowing through the porous wall of the tubular body, and
an annular space consisting of the volume between the annular body and the container wall or pipe section, said annular space is open for gas flow towards the gas outlet.
