Crossflow Scrubber moves contaminated air horizontally through a packed bed and the irrigation process flows down vertically through the packing media for a flexible and efficient removal of various types of contaminants from gas streams. Crossflow Scrubbers can be very effective especially when using a caustic solution to scrub an acid gas. When faced with space restrictions the horizontal design combined with lower pressure drops and higher capacities make the Crossflow Scrubber a desirable option.
