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.
Fans in this process
| Duty | What it does here | Type usually selected |
|---|---|---|
| High Pressure Blower | Delivers combustion, aeration and conveying air where the system resistance runs to several thousand millimetres of water column in a single stage.. | Backward curved and radial tipped |
| ID Fan | Sits at the outlet of a boiler, kiln or furnace and draws the flue gas through the plant to the stack. | Backward curved, backward inclined and radial tipped |
| Fume Exhaust System | Hoods, ducting and an exhaust fan that capture fume at source and deliver it to a scrubber, bag filter or stack. | Backward inclined and radial tipped |
| Mist Eliminator | Separates entrained liquid droplets from a vapour or gas stream, ahead of a compressor, a fan or a stack.. | Demister Knockdown Vessel |
