MAGNESIUM SULPHITE-SPLITTING - MSSFeatures
for the magnesium sulphite splitting process. In Detail
Acid sulphite 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 magnesiumsulphite - provides the means for direct SO2 - recycling and reduces the costs of make-up chemicals and the level of emissions. |
