1. A cyclone separator (1) for separating liquid from a flow (8) of gas and liquid, whereby the cyclone separator comprises a housing with a mainly tubular inner wall (2), an inlet (3) for the flow being provided in the housing to carry the flow at least partially tangentially against the inner wall, furthermore an outlet (4) being provided at the top of the housing, all so that during operation the flow forms a vortex (5) between the inlet and the outlet, and whereby the liquid (6) impacts against the inner wall due to centrifugal force in order to be discharged (11),
wherein the housing has, at least in a zone above the inlet, a mainly tubular auxiliary wall (7), whereof an outer side is spaced from and directed towards the inner wall, so that during operation the vortex is at least partially bounded by an inner side of the auxiliary wall to reduce contact between the vortex and the liquid at the inner wall, and
wherein the tubular auxiliary wall has a top end and a bottom end, the bottom end being provided at least partially above the inlet.
