The process
Sulphur burning and metallurgical acid plants move gas through the converter and absorption towers with a main blower, and vent the tail gas through a scrubber. Materials follow the acid concentration at each point.
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
| Type | Packed bed for gas absorption |
| Material | PP-FRP or rubber lined |
| Outlet | Mist eliminator ahead of the fan; fan in the same material as the scrubber |
