ABSTRACT:
A method of producing an alkaline earth nitrate fertilizer composition where a gas stream containing nitrogen oxides is treated to convert the nitrogen oxides to nitric acid and the gas stream then contacted with an aqueous medium containing an alkaline earth compound which reacts with the nitric acid to form an aqueous effluent solution of an alkaline earth nitrate. A portion of the aqueous effluent solution is used to form additional aqueous medium containing an alkaline earth compound for further contact with the gas stream, such that the concentration of alkaline earth nitrate in the aqueous effluent is increased.
