Operating Principle :

High Velocity , Contaminanted , Noxious Gas enters a large plenum chamber , wherein the velocity is reduced to provide even gas distribution across the bottom of the Packing support grid. 

The contaminated gas moves slowly through a bed of specifically selected packings which creates a tortuous labyrinth causing the gas to be completely mixed and absorbed into , or reacted with the recirculating scrubbing liquid wash solution. 

The counter current flow of gas and recirculating scrubbing liquid wash solution maintains an absorption driving force throughout the entire depth of the packed bed. 

Fresh make up solution is added to the solution being recirculated to compensate for evaporation and to keep the absorbed contaminant concentration in an effective absorption range. 

The Spray Header , Weir Trough Dustributor evenly distribute the wash solution over the top of the packing bed by specially selected Non Clog Spray Nozzles. 

Clean gas then flows through a chevron type / High Efficiency Mesh Pad Mist Eliminator preventing mist carryover . 

The wash solution is collected in the recirculation sump sized large enough to provide a positive head for the recirculation pump. 

Benefits : 

Upto 99 % efficiencies can be achieved in many applications. For difficult conditions the same can be customised. 

The pressure drop across the scrubber is lowest of the class. 

Low recirculation solution and make up rates required. 

Rugged construction , thick continuously reinforced corners , well designed packing support plates ensure negligible or low maintainance costs. 

Many standard sizes covering air volumes upto 30000 CFM ensure tooling and drawings are readily available.
