| titleOfInvention | METHOD FOR REGENERATING A SOLUTION |
| abstract | The invention relates to a process for enhancing the free SO2 content of regenerated magnesium bisulphite solution from the used cooking liquor from a magnesium bisulphite pulping process, the regeneration of the used cooking liquor comprising the following steps: (a) if necessary, expelling the cooking liquor 1 from the digester K by means of washing liquor and depressurizing the expelled cooking liquor LE (b) emptying the digester K after the digestion process B, (c) separating F the pulp 4 from the cooking liquor or the washing liquor 3 (d) evaporating EDA the cooking liquor 5, (e) burning LK the evaporated cooking liquor 6, (f) obtaining R regenerated magnesium bisulphite solution from the waste gas 7 from step (e), (g) storing the regenerated magnesium bisulphite solution 10 under pressure DS. A process according to the invention is characterized in that at least some of the SO2-containing gases 2, 16, 17 from one or more of the steps (a), (b) or (d) are compressed V, and at least some of the compressed gases are fed into the regenerated magnesium bisulphite solution in step (g) DS. <IMAGE> |
