Mechanical vapour recompression uses a fan or compressor to raise the pressure of the evaporated vapour so it can be reused as the heating medium. It replaces most of the live steam demand with electrical power, which is the right trade when power is cheap relative to steam.
Key features
- Very low or zero live steam demand in steady operation.
- Compact footprint compared with an equivalent multi-effect train.
- Best suited to streams with a low boiling point rise.
