The process
Hexane extraction plants need flameproof construction on every fan in the extraction building, hot air for the desolventiser toaster and meal dryer, and dust extraction on the seed preparation. The seed dryer and cooler fans handle dusty, humid air.
The gas
Air carrying solvent vapour from painting, printing or coating. Spark resistant construction, flameproof or increased safety motor, and the fan placed where the duct cannot accumulate vapour.
Fans in this process
| Duty | What it does here | Type usually selected |
|---|---|---|
| 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 |
| Hot Air Fan | Circulates or supplies air at elevated temperature to a dryer, oven or kiln. | Backward curved and backward inclined |
| 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 |
| Dust Collector Fan | The fan behind a bag filter, cyclone or multiclone on a dust extraction system. | Backward inclined and radial tipped |
| Ventilation Fan | Moves air through a plant or building for fresh air supply, heat removal and fume dilution where the system is ducted. | Backward inclined and forward curved |
| Mist Eliminator | Separates entrained liquid droplets from a vapour or gas stream, ahead of a compressor, a fan or a stack.. | Demister Knockdown Vessel |
