| titleOfInvention | Process for causticizing green liquor |
| abstract | In a method for causticizing of green liquor in a sulfate or kraft process for pulp production in which a consisting of an aqueous solution of sodium carbonate as the main constituent and sodium sulfide green liquor is added in a Slaker with calcium oxide and a reaction in a Kaustifizierer (1 0) to a aqueous suspension containing sodium hydroxide and calcium carbonate as main components, which suspension is filtered off on a first filter (19) and then two to three times after dilution with water in a dilution tank (21, 25) for separating solids suspended therein via further filters (22 , 26) is conducted and filtered, characterized in that the aqueous suspension after a first separation of calcium carbonate as a main component and calcium oxide as a minor component at least during dilution in a dilution vessel (18, 21, 25) and in particular in the (de n) dilution vessel (s) (21, 25) before a second and / or a third filter (22, 26) carbon dioxide is added. |
