| titleOfInvention | Method for preparing complex nitrogen-phosphorus fertilizer |
| abstract | FIELD: chemical industry, fertilizers. SUBSTANCE: invention relates to preparing ammonium nitrate-base fertilizer "nitrogen-phosphate" with addition of water-soluble phosphate. Method involves step-by-step neutralization of nitric acid with ammonia in reactors with addition of phosphoric acid taken in the amount 2-6% as measured for P 2 O 5 of fertilizer mass and feeding to the first neutralization of an aqueous solution containing aluminum sulfate taken in the amount 3.5-10.5 kg of aluminum sulfate per 1 t of P 2 O 5 in fertilizer content. Neutralized solution is evaporated and fed to granulation of product. Addition of aluminum sulfate provides reducing dusting in granulation, transporting and package of product by 2-fold. EFFECT: improved preparing method. 1 ex |
