Method of producing sodium carbonate and bicarbonate spherules from brine

摘要: Free-flowing spherules of sodium bicarbonate are prepared from a carbonate or salt brine, substantially saturated with ammonia, by carbonating the solution, ammonia-saturated brine carbon dioxide in presence 200 to 2500 parts per million water soluble alkaline phosphate. Spherules crystallizing solutions separated as product having bulk density between about 32 48 pounds cubic foot, and screen size 14 100 mesh. Sodium also readily obtained calcining spherules.
