Removal of sulfur oxides from preheater off gases |
摘要 |
Sulfur oxides are removed from a preheater waste gas stream by reacting the sulfur oxides with lime recovered from the off gas stream in a calcining furnace. The method is particularly adaptable for use in a cement manufacturing plant wherein the sulfur dioxides in the waste gases result from the combustion of fossil fuels used for process heat.
