Abstract
A pump system (1) is provided for the pumping of multiphase mixtures which includes a pumping apparatus (3) for multiphase mixtures with at least one liquid phase and at least one gaseous phase. The pumping apparatus (3) contains one or more axial compression stages with one respective axial impeller each and one or more pumping stages with a respective one radial impeller each which are arranged adjoining the axial compression stage or stages, wherein the pump system (1) additionally includes a separator (2) at the inlet side of the pumping apparatus (3) to separate a portion of the gaseous phase and wherein the pumping apparatus (3) is configured for delivery heads larger than 50 m.
Claims12
A pump system for the pumping of multiphase mixtures including a pumping apparatus (3, 30) for multiphase mixtures with at least one liquid phase and at least one gaseous phase, with the pumping apparatus (3, 30) containing one or more axial compression stages (41.4, 41.2) with one respective axial or semi-axial impeller (45.1, 45.2) each and one or more pumping stages (21.1) with one radial impeller (25.1-25.6) each which are arranged adjoining the axial compression stage or stages, characterised in that the pump system (1) additionally includes a separator (2) at the inlet side of the pumping apparatus (3, 30) to separate the gaseous phase or a portion thereof;
- and in that the pumping apparatus (3, 30) is made for delivery heads larger than 50 m.
A method for the pumping of multiphase mixtures with at least one liquid phase and at least one gaseous phase, the method including pumping a multiphase mixture by means of a pumping apparatus (3, 30) which contains one or more axial compression stages (41.1, 41.2) with one respective axial or semi-axial impeller (45.1, 45.2) each and one or more pumping stages (21.1) with one respective radial impeller (25.1, 25.4) each which are arranged adjoining the axial compression stage or stages, characterised in that the gaseous phase or a portion thereof is separated in a separator (2) at the inlet side of the pumping apparatus (3, 30);
- and in that the liquid phase or the residual multiphase mixture is pumped to a delivery head of more than 50 m by means of the pumping apparatus (3, 30).
