Reagent Preparation And Dewatering In A Wet Fgd System

Reagent Preparation And Dewatering In A Wet Fgd System If limestone consumption must be increased to improve SO2 removal, the reagent preparation and dewatering systems may be undersized. In most cases, higher SO2 removal requires a finer grind than what older systems were originally designed to achieve. The standard grind on modern wet FGD systems is 95 passing through a 325 mesh.If limestone consumption must be increased to improve SO2 removal, the reagent preparation and dewatering systems may be undersized.
