Abstract

The present invention concerns a method for making an alkaline pulp preparation process more efficient, in which method the black liquor used in the digestion of wood chips and washing filtrate which arises during washing of the pulp is recirculated in the digestion section, the washing section, and between them. According to the invention, the black liquor and the washing filtrate are treated prior to recirculation, in order to adjust the sodium content so that the soft soap which is dissolved in same is salted out and separated from the solution. For example, white liquor can be added to the solution. <IMAGE>
