The process
Stenters circulate hot air through the fabric in each chamber with plug fans and exhaust the moist air carrying oil mist and lint. Exhaust fans and ducts are built for cleaning, with mist elimination or scrubbing where the oil load is high.
The gas at the fan
Air saturated with moisture from drying, with condensation on any cool surface. Drainage, a shaft seal and a material that tolerates wet running are part of the specification.
Selection for this duty
| Construction | Stainless steel or lined vessel with mesh pad or vane pack sized for the droplet load |
| Density at the fan | At about 120°C the gas density is close to 0.90 kg/m³, 75% of standard air. Pressure developed and power drawn fall in the same ratio, so the selection is made at this density and the motor is checked at cold start. |
Separates entrained liquid droplets from a vapour or gas stream, ahead of a compressor, a fan or a stack. Client-stated blade types for the Mist Eliminator in general: Demister Knockdown Vessel.
