Gas washing — scrubbing a process or exhaust gas stream to remove particulate, acid gases, or odor before it leaves the stack — puts spray equipment in one of the harshest duty cycles in industry: continuous operation, corrosive scrubbing liquor, high temperatures, and a liquor stream often loaded with the very particulate being removed. A nozzle that clogs in a scrubber does not fail quietly; it creates a dry zone in the packing or spray bank that lets untreated gas pass straight through, jeopardizing emissions compliance. Reliable gas washing depends on a full and even spray pattern across the vessel cross-section, a free passage generous enough to resist plugging from suspended solids, and materials that hold up to sustained chemical attack. BEX manufactures nozzles built for this duty, including Full Cone and Hollow Cone threaded nozzles for particulate-laden scrubbing liquor.
