Transcript of SO2 Emissions

Prevention • Main contributors of sulfur dioxide are motor vehicle and industry emissions

Vehicle sulfur emission (especially PM) affect human health (respiratory problems)
• Local areas are also affected (building corrosions)
o Industry emissions cause acid rain and affect the environment on a larger scale
• Processes such as metal smelting and wood and pulp also emit sulfur oxides Emission So…What Did We Learn? SO2 containing flue gas contacts alkaline sorbent (most often lime)
dry waste is produced with handling properties similar to fly ash
the sorbent can be delivered in a slurry form or dry powder form
SO2 removal lower than wet FGD Our Focus: Dry FGD Flue Gas Desulfurization
Commercially available FGD technologies
“Sorbent treatment” – SO2 absorption
Disposal: waste or gypsum
Action in re-generable
Wet waste vs. dry waste
Commercial Applications FGDs FGDs Emission SO2 circulating dry scrubber technology
