Abstract

The process consists in : (a) causing the black liquor resulting form a delignification process to undergo one or more anaerobic treatments, (b) evaporating the liquor resulting from the anaerobic treatment, (c) causing the concentrated black liquor to undergo an oxidation treatment, (d) recovering the alkaline sodium salts by means of different solubility, (e) causing the separated alkalis to undergo a decarbonation and (f) recausticizing part of carbonates in sodium hydroxide.
