Beschreibung
Zusammenfassung:	A fertilizer composition containing an alkaline earth nitrate, such as calcium nitrate or magnesium nitrate is produced by the scrubbing of hot combustion gases to remove sulfur dioxide and nitrogen oxides from the gas. After removal of sulfur dioxide from a gas stream, a humidified gas stream containing NOx is treated to convert the NOx to nitric acid, and the nitric acid-containing humidified gas stream is contacted with an alkaline earth compound which reacts with nitric acid to form an alkaline earth nitrate in an aqueous effluent, which effluent comprises a fertilizer composition.
