Abstract. This paper summarizes C-E experience regarding the impact of chlorides on flue gas desulfurization system (FGDS) design. The effect of chloride on alloy selection, SO/sub 2/ absorption, scale control, and additives use as well as techniques that may be used to limit chloride concentration in lime/limestone FGD systems are discussed.
LIMESTONE HANDLING & MIXING INCORPORATING THE VACUCAM® EJECTOR MIXER PROCESS Semi-Bulk Systems has applied its technology and experience in Powder Handling & Powder/Liquid Mixing to provide the most efficient Limestone Handling/ Slurry Processes for FGD. The Technology offers many benefits over conventional slurry processes.
alternatives for Unit 2, including dry FGD and wet limestone FGD at the plant, it was decided to provide a new wet, forced oxidized lime FGD system for Unit 2. As part of the project it was decided to provide a new, common lime reagent storage and preparation facility and waste disposal facility to cover both Units 1 and 2. The old,
