| 摘要 |
The present invention relates to a method of treating condensates containing compounds, which are more volatile than water, in an evaporation plant, where liquid, such as effluent liquid from a pulp or paper mill is evaporated in multiple effects and where condensates generated in the evaporation are flashed and purified in a steam stripping column. In the method, the condensates from at least two evaporation effects are combined and flashed together, and the vapor obtained from the flashing is made to contact with a condensate stream to be purified in the stripping column, wherefrom the impurities-containing vapor and the purified condensate stream are discharged. |
