The process
Mechanical vapour recompression raises the pressure of the vapour leaving an evaporator so it can heat the calandria, replacing live steam. The blower handles saturated, often corrosive vapour at a precise pressure ratio, in stainless steel, with a knock-out vessel ahead of it.
The gas
Saturated vapour, often with dissolved solids and a low pH. Wetted parts in stainless steel, a shaft seal rated for the vapour, drain points and a casing designed for condensate.
Fans in this process
| Duty | What it does here | Type usually selected |
|---|---|---|
| MVR Blower | Recompresses the vapour leaving an evaporator so it can be reused as the heating medium. | Backward 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 |
| 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 |
