Abstract: Scrubber for separation of liquid phase and any other constituents from a fluid flow that in substance is comprising a gas, which scrubber is formed as a standing vessel with round cross section, with oulet for liquid from the bottom and outlet for gas from the top. The scrubber is distinguished in that it is comprising: a fluid inlet that either is tangetially oriented to the inner wall of the scrubber or equipped with a deflection plate, such that introduced fluid is directed tangentially horizontal or with a small downward slope along the inner wall of the scrubber, into and through a fluid way arranged as a downwards directed spiral within the scrubber, along the inner wall, from a level over or at the inlet to a level at or close to the outlet for liquid, with opening for gas escape inwards of the center of the scrubber. The scrubber according to the invention results in very low liquid entrainment.
