A state-of-the-art review of dry FGD processes, based on a project carried out by SCS Engineers Inc. for the Electric Power Research Institute, covers dry injection of an additive sorbent to remove fly ash and some sulfur dioxide; spray dryers, and other dry FGD systems; the alkaline sorbents (nahcolite, sodium bicarbonate, trona, soda ash, lime, limestone, fly ash, dolomite, and ammonia) and their reactions with sulfur dioxide; characteristics of the wastes generated by dry injection and spray drying, including chemical analyses of the sodium-based and calcium-based wastes; recovery, reuse, and utilization of coal-combustion waste products, including sulfur dioxide absorption and direct recovery, regeneration of sodium compounds, and recovery of nitrogen dioxide for use in fertilizer manufacture; and the ultimate disposal of dry FGD wastes by landfilling, dry impoundments, or mine disposal (after solubility reduction by pelletizing or the Sinterna, Fersona, or Alsona processes and stabilization by the Dravo, Poz-O-Tec, and Chemfix processes), and by ocean disposal; and future research and development needs.
