SOx Emission and Its Control
- Sulphur is relatively inert and harmless to human beings.
- Oxides of sulphur poses serious environmental problem.
- Sulphur oxides are corrosive in nature.
- Organic fuels such as coal, oil, wood, etc contain some sulphur.
- SO is a highly reactive radical and its life time is few milliseconds.
- Under fuel rich conditions, in addition to sulphur oxides, hydrogen sulphide, carbonyl sulphide, and elemental sulphur are formed.
- Understanding of the mechanism of sulphur oxides have not evolved to a maturity level.
