ABSTRACT:
The present invention relates to a device to compress a multiphase fluid such as petroleum effluent comprising a liquid phase and a gaseous phase and a method to use the device. The device comprises a housing (1), an impeller having an inlet section and an outlet section. The impeller comprises an axisymmetric hub (28) with an axis Ox and a number n of blades rotating around the axis. The blades have a leading edge (C1, C2) and a trailing edge (C'1, C'2). The fluid enters the impeller va the inlet section (41) and leaves via the outlet section (42). The axis is orientated in the direction of advance of the fluid. The number of rotating blades (29, 30) is equal to or greater than 2. At least one channel or passage is defined by two successive blades (29, 30) whose orthoradial section S(x) is of the form, within 5% and preferably within less than 3%:
