Claim:
A scrubber for separating constituents including a liquid phase from a substantially gaseous fluid flow comprising: a standing vessel having a substantially round cross section, an inner wall, a lower liquid outlet and an upper gas outlet; a fluid inlet directing fluid introduced into the standing vessel along the inner wall; and a fluid way that is arranged as a downward directed spiral along the inner wall of the standing vessel, that extends from the vicinity of the fluid inlet to the vicinity of the liquid outlet, and that has an opening allowing gas to escape inward to a central region of the standing vessel, such that all fluid introduced into the fluid way is passed down the full length of the fluid way, except the escaped gas, wherein the fluid way comprises a spiral-shaped pipe placed within the standing vessel, and the spiral-shaped pipe is oriented in direct elongation from a tangential inlet, extends to just above the liquid outlet, and has at least one opening for gas escape.
