sentences:  Cyclonic, mesh-pad, and blade separators are all used to remove liquid droplets from the flue gas and return the liquid to the scrubber water.Cyclonic separators, the most popular for use with venturi scrubbers, are connected to the venturi vessel by a flooded elbow (Figure 8).The liquid reduces abrasion of the elbow as the outlet gas flows at high velocities from the venturi into the separator.
