APPLICATION FACT SHEET

Scrubbers

Scrubbers are one of the primary devices that control gaseous emissions especially acid gases. Scrubbers can be used to remove some particulates and/or gases from industrial exhaust streams. These can also be used for heat recovery from hot gases by flue gas condensation. GFRP which can sustain in highly corrosive environment is used as the material of construction for scrubbers.

Packed bed scrubber enlarges surface between exhaust gas and fluids, purifying easily hazardous exhaust gases with its internal special filling pieces. Packed with hollow thermoplastic elements, these are capable of removing soluble gases like chlorine, bromine, HCL, NH2, SO2, H2S etc. In counter to the descending scrubbing liquid, the ascending gas stream gets fluidized by the thermoplastic elements in the passage.

Efficiency of a scrubber generally depends on the interfacial area between the liquid, gas and the turbulence at the interface. Along with uniformity in distribution and flow of the liquid, the packing area also ensures high interfacial area per unit volume. The column diameter is designed taking into consideration the gas and liquid flows whereas the required concentration change is the parameter for designing column height.
