Verfahren und Vorrichtung (10) zum Entgasen von Flüssigkeiten, bei dem die Flüssigkeit radial nach außen und das leichtere Gas radial nach innen in Richtung auf den Rotor (12) einer Zentrifugiervorrichtung gefördert wird. Der Rotor (12) ist mit einer durchbrochenen Tragscheibe (13) und einer durchbrochenen Deckscheibe (14) versehen. Das radial nach innen geförderte Gas gelangt durch einen Gasaustritt (19) in die umgebende Atmosphäre. The device for degassing liquids comprises a housing (11) containing a rotor (12), rotatable about a central axis (28). The rotor comprises a perforated bottom disk (13) with a spaced apart, perforated upper cover disk (14). In use, liquid containing dissolved gas enters the housing (11) via a bottom inlet (26), and exits via a top, peripheral ou (20); displaced gas leaves the housing by a top, axial outlet (19), and collects in a chamber (27) , for release through a valve (23). The level of gas removal is controllable by varying the rotational speed, or by throttling the liquid flow. Preferably the rotor is driven by an electric motor, which may be a canned/external stator, glandless arrangement.
