摘要
The present invention relates to a method of producing chemical pulp at a con¬ tinuous digester plant. The method comprises the following steps: a) leading a slurry formed of comminuted cellulosic fibrous material and liquid into a digester and treating the material with a treatment chemical at a temperature over 130 °C for producing treated material and black liquor; b) extracting at least one black liquor stream from the digester and leading the black liquor into an indirect heat exchange relationship with steam in a heat ex¬ changer for heating the black liquor; c) leading the heated black liquor into a flashing vessel, wherein flash steam and flashed black liquor are generated, and d) using flash steam from step c) for heating the fibrous material in the digester in step a).
