Abstract
This project addresses the problem of flue gas desulfurization (FGD) sludge disposal to land. Specifically, the chemical species of FGD sludge constituents are thermodynamically modeled using the equilibrium constant approach, in an attempt to predict the constituent concentrations in fresh and aged FGD wastewater and sludge. This method involves solving the stoichiometric equations of various chemical species, which are subject to constraints imposed by the equilibrium constants as well as mass balance and charge balance relations. Diagrams, such as Eh-pH plots, ion-ratio plots, concentrations pH figures, and species distribution figures, are then used to display the stability field and speciation results.
