Abstract
A process of using sodium carbonate and sodium bicarbonate solutions to remove SO and other acidic gases or vapors from a flue gas without substantially decreasing the amount of sulfur dioxide also present in the flue gas. Very limited quantities of such solutions are injected into the flue gas in a manner that achieves a controlled droplet size, such that the solution dries on contact with the flue gas and the resulting dry particles of sodium carbonate/bicarbonate are sufficiently small as to have adequate surface area for reacting with SO , as well as any H SO and, to some extent, HCl vapors in the flue gas.
