Abstract

See full text

The invention relates to a rotodynamic separator (30) for separating a liquid and a gas from a multiphase fluid, notably for use in the petroleum industry. This separator comprises a cylinder (12) freely rotating about an axis (xx), a substantially axial inlet (1) for the multiphase fluid, a liquid outlet (5) and a gas outlet (6). At least one vane assembly (15) arranged along axis (xx), in the direction of circulation (F) of said multiphase fluid, is installed and integral with cylinder (12). Vanes (15) are directed towards axis (xx) of cylinder (12). Furthermore, the inside diameter of vanes (15) decreases progressively, in the part of the separator located upstream from the outlet of the second phase, in the direction of circulation of the multiphase fluid, while remaining larger than the inside diameter of gas outlet (6).
