Apparatus for separation of a liquid from a multiphase fluid flow

Abstract

An apparatus for separation of a liquid from a multi-phase fluid flow flowing through a pipeline, wherein the fluid flow is set in rotation so that it is separated into a central zone (5) essentially containing gas, and an outer annular zone (6) essentially containing liquid, and from which the gas and the liquid in the two-zones are discharged via respective outlet means (10, 16). The apparatus comprises an essentially tubular casing (1) arranged to constitute a part of the actual pipeline, a spin element (4) for rotation of the fluid flow being located at the upstream end of the casing (1). The outlet means for the gas comprises an outlet element (10) arranged at the downstream end of the casing (1) and having a central, axially extending passage (11) for the gas, and an outer surface which, together with the inner surface of the casing (1), forms an annulus (12) for the inflow of liquid, a barrier (15) for the liquid being formed at the downstream end of the element (10). The outlet means for the liquid comprises an upwards open container (16) arranged at the downstream end of the casing (1) and adapted to receive liquid which flows into the annulus (12) and partly runs down into the container (16) from the bottom area of the casing (1) at the container opening, and partly falls into the container from the area at said barrier (15).
