| titleOfInvention | Method for production of complex nitrogen-phosphorous fertilizer |
| abstract | FIELD: chemical industry, agriculture. n SUBSTANCE: invention relates to method for production of double NP-fertilizer containing 3-7 mass % of P 2 O 5 from concentrated ammonium nitrate solution and extractive phosphoric acid solution. Starting phosphoric acid (52-54 %) is diluted with weak ammonium nitrate solution, diluted solution is additionally treated with ammonium nitrate to produce NH 4 NO 3 :P 2 O 5 ratio in ammoniated solution not less than 3:1, wherein ammoniating is carried out simultaneously with auxiliary treatment or thereafter. Ammoniated solution is boiled down to produce residual water content of 5-20 mass % and mixed with concentrated ammonium nitrate solution. Then obtained solution is finally neutralized with ammonia, boiled down and grained. Phosphorous content in ammoniated solution is maintained preferably from 4 to 10 mass % calculated as P 2 O 5 , and as ammonium nitrate in auxiliary treatment of diluted solution preferably concentrated ammonium nitrate solution obtained by nitric acid neutralization with ammonia or 40-50 % solution obtained by conversion of calcium nitrate with ammonium carbonate is used. n EFFECT: simplified method for production of complex nitrogen-phosphorous fertilizer. n 5 cl, 3 ex |
