The Electric Power Research Institute, EPA, the Empire State Electric Energy Research Corp., and the New York State Energy Research and Development Administration are initiating a study program to demonstrate the viability of Rockwell International's Aqueous Carbonate Process, for simultaneously controlling sulfur dioxide emissions from powerplant flue gases and producing a sulfur product. A sodium carbonate solution is sprayed into the gas stream, and the resulting dry solids are heated with coal to 1800/sup 0/-1900/sup 0/F in a reactor and are then fed to a series of columns which produce hydrogen sulfide and regenerate the sodium carbonate. Finally, the hydrogen sulfide is converted to sulfur. The project would include a year-long test program with an estimated cost of $51 million to be conducted at a 100 Mw test facility (target completion date mid-1981) at Niagara Mohawk Corp.'s Huntley Station. The Aqueous Carbonate Process does not require expensive reducing gases; does not produce sludge; and does not cause plugging and scaling problems.
