摘要 |
A method and arrangement for increasing evaporation capacity in a multi-stage evaporation plant of spent liquor of a pulp mill. The method includes increasing the pressure of vapor discharged from an evaporation stage by a separate booster, and supplying the vapor having increased pressure to the following evaporation stage.
