One of the key factors that influences the materials selection process for a FGD system is the anticipated environmental conditions. Due to the wide variations in coal burned, a method was needed that could predict the environment that would be generated. A computer model has been generated that will predict, with some degree of accuracy, the maximum concentration of sulfuric acid that will form by condensation at the inlet and the outlet of the scrubber. Having generated the model, experiments were performed to confirm the predictions by collecting samples from an operating FGD system and analyzing the acid content.

Results generated have confirmed that acid concentration in the duct work can be anticipated and the effects of other process variables such as reheat can be predicted.
