| Abstract |
The report describes a series of open- and closed-loop laboratory bench scale experiments which were carried out to study parameters which affect the reaction of limestone with dual alkali flue gas desulfurization system process liquors. It gives details of several sets of operating conditions which permitted good limestone utilization to be achieved and product solids with good dewatering properties to be produced. It discusses the effects of temperature and soluble magnesium on the behavior of the regeneration reaction as well as the effects of total sulfur (IV) concentration, ionic strength, acidity of the solutions, and reactor system configuration. It presents data which suggest that regenerated liquors may have been unsaturated with respect to magnesium sulfite as a result of its coprecipitation with the calcium sulfite product solids. |
