• ### METHOD OF CALCULATION OF THEORETICAL SO2

· 2. The emissions calculated are the maximum theoretically possible with the data of S and Excess air applied . In practice the actual emissions are somewhat lower due to the fact that part of the SO2 is converted into Sulphates (basically of calcium) and part into SO3. The calculation thus represents the maximum emission
