Abstract

La présente invention concerne un procédé de préparation de pâte dans lequel un acide est ajouté à la liqueur noire. L'acide provoque l'insolubilité de la lignine, ce qui permet de la séparer de la liqueur noire. L'invention permet d'éviter le besoin d'une chaudière de récupération qui brûle les sucres et la lignine. En outre, dans ce procédé des sels de sodium sont précipités. Dans ce procédé, on utilise du carbonate de sodium provenant de sources extérieures.
