CA 2446407

The present invention relates to a separation method of fibre and fibre-based material and lipophilic extractive material; the method permits a reduction in the water consumption of a pulp mill and the use of wood species having higher extractives content in the mechanical and chemi-mechanical pulp production. In a preferred embodiment of the invention, a decanter centrifuge is used to recover solids and to separate solids and lipophilic extractives. With a decanter centrifuge a situation is reached in which the colloids containing lipophilic extractive material do not settle but fibre and fibre-based solids settle due to a higher density.

L'invention concerne un procédé de séparation de matériau fibreux et à base de fibres et de matériau d'extraction lipophile. Ce procédé permet une diminution de la consommation d'eau d'une usine de pâtes et l'utilisation d'espèces de bois possédant une contenu de produit d'extraction supérieur dans la production mécanique et chimio-mécanique des pâtes. Dans un mode de réalisation préféré de cette invention, un centrifugeur décanteur est utilisé pour récupérer les solides et pour séparer les solides et les produits d'extraction lipophiles. A l'aide d'un centrifugeur décanteur, les colloïdes contenant du matériau d'extraction lipophile ne précipitent pas, mais les fibres et les solides à base de fibres précipitent à cause d'une densité supérieure.
