Proven system for removal of noxious and corrosive contaminants from the gases generated by varoius process plants. The gas is washed with suitable liquid medium using spray nozzles or atomizers. Suitable packed bed provides large contact surfaces for the gas and liquid to mix and hence traps the contaminants. Low pressure drop and low liquid flow brings down operating costs. Provisions will be made for suitable dosing methods to neutralise the toxic nature of the saturated water before letting out to ETP.

The material of construction would be of Mild Steel MS/ FRP/SS depending on the application. The packed beds are usually PP/PVC Pal rings, saddles etc to suit the various toxic gases.
