| titleOfInvention | Process for recausticizing green liquor |
| abstract | In a process for recausticizing green liquor in a sulphate or craft process for wood pulp production, in which a green liquor consisting of an aqueous solution of sodium carbonate as main component and sodium sulphide is admixed in a slaker with calcium oxide and is subjected to a reaction in a recausticizer (10) to give an aqueous suspension containing sodium hydroxide and calcium carbonate as main components, which suspension is filtered off on a first filter (19) and subsequently passed over further filters (22, 26) two or three times after dilution with water in a dilution vessel (21, 25) and filtered for separating off solids suspended therein, characterized in that, after a first separation of calcium carbonate as main component and calcium oxide as minor component, at least during a dilution in a dilution vessel (18, 21, 25), and in particular in the dilution vessel(s) (21, 25), carbon dioxide is added upstream of a second and/or a third filter (22, 26) to the aqueous suspension. |
