Abstract
A method of removing liquid from the surface of an airfoil of equipment that handles a wet gas mixture. The airfoil has at least one interior passage, such as a bore, for travel of air or other gas through the interior of the airfoil. A series of holes are cross drilled from one or both exterior surfaces of the airfoil to the passage. Forced air or other gas is introduced into the passage such that the air or other gas is expelled to the surface of the airfoil via the holes, thereby removing the surface liquid.
