Patent ID: 8226743

Claim:
A fluid separator for separating a fluid, the fluid separator comprising: a throat portion which is disposed between a converging fluid inlet section and a diverging fluid outlet section, the diverging fluid outlet section comprising an inner primary outlet for condensables depleted fluid components and an outer secondary outlet for condensables enriched fluid components; a central body disposed upstream of the throat portion and in the converging fluid inlet section, the central body being disposed substantially coaxial to a central axis of the fluid separator, wherein the central body has a largest outer width or diameter which is larger than a smallest inner width or diameter of the throat portion; and a swirl imparting device for creating a swirling motion of a main flow within at least part of the fluid separator, wherein the fluid separator further comprises a housing in which the central body is disposed such that an annulus is present between an inner surface of the housing and an outer surface of the central body, wherein the fluid separator is configured to facilitate the main flow through the converging fluid inlet section and the throat portion towards the diverging fluid outlet section, and wherein the central body comprises a central body outlet directed towards the throat portion and configured to add a central flow towards the throat portion.
