Abstract

The method involves separating free liquid from a cellulose tip through a top separator (20). The cellulose tip is arranged on a transfer circuit (11) that is arranged at a top part of a digestion apparatus (30). A collection space is formed on the top separator to collect the free liquid. A guide part is provided with a return line (32). Pressurization recovery of black liquor is performed in the digestion apparatus. Inlet temperature of the free liquid is higher than outlet temperature of the free liquid.
