Abstract: The invention provides a separator blade for a mist eliminator of the kind comprising a plurality of parallel blades providing corresponding flow passages that change direction. A first direction change occurs immediately upon entry to the flow passage so that droplets are deposited on the blade front face. This part of the front face terminates in a primary collecting channel formed by a hook-like member protruding into the passage. The outer face of this hook-like member is convex curved and forms a venturi throat with the facing rear face of the adjacent blade. The blade is shaped to change the passage direction immediately after the throat and to provide an impingement surface at right angles to the gas flow that leads immediately into a secondary collecting channel formed by a respective hook-like member protruding into the passage from the rear face.
