Flue Gas Desulfurization (FGD) - The National Lime Association

In a CDS system, flue gas is treated by injecting a mixture of dry hydrated lime or lime slurry and recycled by-product (a mixture of reaction products (CaSO3, CaSO4), excess lime (Ca(OH)2), and fly ash). Preparation of hydrated lime requires the use of a lime hydrator (an atmospheric hydrator is analyzed in this report).
