| titleOfInvention | Procedure for the causticification of green liquor |
| abstract | Method for causticizing the green liquor in a sulphation or Kraft process for the production of cellulose, in which a green liquor consisting of an aqueous solution of sodium carbonate as the main component and sodium sulphide is mixed with calcium oxide in a lime softener and undergoes a conversion into a causticizer (10) to form an aqueous suspension containing sodium hydroxide and calcium carbonate as main components, whose suspension is passed through a first filter (19) and subsequently, and After diluting it with water in a dilution vessel (21, 25), it is supplied to more filters (22, 26) two to three times to filter it and separate the solid substances suspended therein. This procedure characterized in that after a first separation of calcium carbonate as the main component and calcium oxide as the secondary component, carbon dioxide is added to the aqueous suspension at least during dilution in a dilution vessel (18, 21 , 25) and in the dilution vessel or containers (21, 25) before a second and / or third filter (22, 26). |
