Process for treating flue gas |
摘要 |
A coal or petroleum combustion flue gas containing sulfur oxides and dust is treated by contacting the flue gas with a sulfur dioxide-oxidizing catalyst, thereby converting sulfur dioxide to sulfur trioxide, allowing the resulting sulfur trioxide to react with components of dust, absorbing the trioxide into the dust as a sulfate, and removing the dust. Catalytic oxidation of sulfur dioxide can be efficiently carried out at a low temperature and sulfur oxides can be efficiently removed from the flue gas.
