Desulphurisation of Waste Gases by Dry Additive Method
Veselý, Václav ; Čech, B.
The molar ratio Ca/S is the most frequently for comparison of efficiency and effectiveness of desulphurisation. Desulphurisation of waste gases by a dry additive method is based on the known fact that calcium oxide with sulphur dioxide and oxygen reacts to stable calcium sulphate at high temperatures (850 up to 950°C).
