The process
Reactors, storage tanks and process vents release acid, alkali or organic vapour that is scrubbed before discharge. The vent fan is in PP-FRP, FRP or stainless steel to suit the vapour, with the motor outside the gas path and a mist eliminator on the scrubber outlet.
The gas
Fume from pickling, acid handling or reactor vents, corrosive and often wet. PP-FRP, FRP or rubber lined construction, with the motor outside the gas path.
Selection for this process
| Carbon | Granular activated carbon bed sized for the solvent load and the required outlet |
| Fan | Spark resistant, on the clean side of the bed |
