ABSTRACT:
A method of reducing acid emissions and ozone deletion precursors from a flue gas produced by the combustion of sulphur-or nitrogen-containing fuel or acid emissions and ozone deletion precursors from chemical plants. The method comprises introducing into a flue containing the gas, an additive derived from the chemical reaction of pyrolysis liquor with an alkaline earth metal compound in the presence of an oxidant. This reaction produces a hydrophobic/hydrophilic mixture containing a plurality of thermolabile alkaline earth metal compounds. These compounds are able to decompose at flue gas temperature to produce an alkaline compound able to react with sulphur dioxide and oxides of nitrogen to eliminate them from the gas.
