Abstract (en)
[origin: WO0240767A1] A method for recovering non-fibrous substances from wood material being processed in a mechanical pulping process, such as TMP process or groundwood process. Non-fibrous substances, such as wood resins, aromatic components, salts and polysaccharides, are extracted from said wood material into a liquid fraction, such as process water or other suitable water based liquid. The recovery of non-fibrous substances from the liquid fraction includs separation of aromatic compounds from said liquid fraction, while preferably maintaining the pH-level of the liquid fraction < pH 7, during the extracting and recovering processes.
