Valmet MVR Evaporators

MVR (Mechanical Vapor Recompression) is a good way to improve the mill’s overall steam economy and condensate segregation.

Valmet’s MVR evaporators are optimized for minimum fan power, which lowers the operating cost.

In an MVR Evaporator, a fan or turbine drives the evaporation. The fan creates energy for the evaporation by increasing the steam pressure.

Valmet’s MVR evaporators are designed for low fan power. This lowers the cost of energy and thereby the operating cost for the MVR evaporators.

MVR Evaporators are especially suitable for concentrating liquors with a low boiling point rise. MVR is often used for black liquor pre-evaporation, evaporation of sulfite spent liquor and evaporation of mill effluents. BCTMP mills can often benefit from installing MVR evaporators.
