ABSTRACT:
In a magnetohydrodynamic power plant where calcium carbonate seed is used to increase conductivity and scavenge sulfur, forming potassium sulfate, an improved process is disclosed for converting the potassium sulfate back into potassium carbonate for reuse in the power plant. The potassium sulfate is first reacted with a reducing agent in the presence of up to about 40% boric oxide at about 800.degree. to about 1300.degree. C. for at least about one hour to produce potassium sulfide. The potassium sulfide is then reacted with carbon dioxide and steam at about 450.degree. to about 750.degree. C. for at least about an hour to produce hydrogen sulfide and potassium carbonate. Finally, the potassium carbonate and the hydrogen sulfide are separated and the potassium carbonate is recycled.
