Magnesium Sulfite-Splitting - MSS
Features
- Optimized cooking liquor composition
- Reduced chemical losses
- Production of recycled SO2
In Detail
Acid sulfite cooking requires the addition of free SO2 into the cooking liquor. This causes an unbalanced ratio of MgO to SO2.
MgSO3 => MgO + SO2
This process step - the thermal decomposition of magnesium sulfite - provides the means for direct SO2 - recycling and reduces the costs of make-up chemicals and the level of emissions.
