ABSTRACT

Flue gas emitted from coal-fired power plants is one of the major sources of sulfur and nitrogen oxides emissions to the atmosphere. Flue-gas desulfurization (FGD) is a pollution prevention method that is employed to meet regulatory requirements using scrubbers.

FGD wastewater contains high concentrations of dissolved salts which limit options for recycling and reuse. This thesis focused on treating FGD wastewater with a combination of ion exchange (IX), precipitation, and nanofiltration (NF) …

Flue gas emitted from coal-fired power plants is one of the major sources of sulfur and nitrogen oxides emissions to the atmosphere in the world today. Although coal use has decreased, it is still a major contributor to such emissions. The Clean Air Act in the United States established regulations for coal-fired power plants to limit SO_x and NO_x emissions into the atmosphere. To meet regulatory requirements, power plants have been using scrubbers to limit their air emissions. Flue-gas desulfurization (FGD) is a pollution prevention method that is employed to limit sulfur dioxide emissions directly in the environment …
