Pressure diffusers – ideal after overloaded digesters
Valmet’s pressure diffusers are primarily used for washing in a digester blow line and as a first washing stage in an oxygen delignification system.
Pressure diffusers operate under pressure, which means that temperatures over 100 °C can be processed. This makes pressure diffusers ideal as washing equipment after overloaded digesters.
Advantages of Valmet’s pressure diffusers
- Excellent washing efficiency
- Pressurized operation
- Ideal for capacity upgrades
- Easy and reliable to operate and control
- Quick startup and shutdown
- Quick installation
- Environmentally friendly
Pressure diffuser - Process and automation upgrades
