| abstract |
The present invention provides compositions including a salt selected from the group consisting essentially of sodium nitrate, sodium nitrite, ammonium nitrate, lithium nitrate, barium nitrate, cerium nitrate, and mixtures thereof, as flue gas conditioning formulations for use in controlling particulates, hazardous substances, NOx, and SOx. For the purpose of obtaining greater yields of particulate and hazardous substance removal, the compositions may further include a polyhydroxy compound, preferably selected from the group consisting essentially of sucrose, fructose, glucose, glycerol, and mixtures thereof. Methods are also provided for adding these compositions to the flue gas stream to control particulate, hazardous substance, NOx, and SOx emissions. |
