Description
Przy wytwarzaniu nawozów z azotanu wapnia proponowano ten ostatni mieszac z mala iloscia azotanu amonu, dzieki czemu otrzymuje sie pewne korzysci, miedzy in- nemi i te, ze mieszanka soli zawiera wiek¬ sza zawartosc azotanu niz azotan wapnia, Azotan wapnia mozna wytwarzac przez rozpuszczenie w kwasie azotowym wegla¬ nu wapnia. W mysl wynalazku stosuje sie w tym celu weglan wapnia, który otrzymu¬ je sie jako produkt uboczny przy przetwa¬ rzaniu na siarczan amonu i weglan wapnia siarczanu wapnia zapomoca amonjaku i kwasu weglowego. Wymagana ilosc siar¬ czanu amonowego pozostawia sie przy wy¬ twarzaniu w powyzszym weglanie wapnia, pbczem mieszanine traktuje sie kwasem a- zotowym. Obecny siarczan amonu, z odpo¬ wiednia iloscia kwasu azotowego i weglanu wapnia, przetwarza sie przytem podlug na¬ stepujacego wzoru: Am2S04+2 HN03+CaC0^2 AmNOs+ + CaSO± + C02 + H20.Dzieki powyzszemu procesowi ma sie ten zysk, ze sie unika gruntownego plóka- nia weglanu wapnia w celu otrzymania przywierajacego do niego roztworu siarcza¬ nu amonowego; upraszcza sie wiec zarów¬ no aparature jak i sposób.Wytworzony rozczyn mozna, zaleznie od okolicznosci, oddzielic od straconego przy reakcji siarczanu wapnia i innych pro-duktów nierozpuszczalnych i wyparowac stala w nim iloscia rozczynu siarczanu a- do sucha albo wspólnie z powyzszemi pro¬ duktami. PLIn the manufacture of fertilizers from calcium nitrate, it has been proposed to mix the latter with a small amount of ammonium nitrate, thanks to which certain advantages are obtained, among others, that the salt mixture contains a greater content of nitrate than calcium nitrate. Calcium nitrate can be prepared by dissolving in nitric acid, calcium carbonate. In the context of the invention, calcium carbonate is used for this purpose, which is obtained as a by-product in the processing of ammonium sulfate and calcium carbonate, calcium sulfate by means of ammonia and carbonic acid. The required amount of ammonium sulfate is left in the above calcium carbonate in the preparation of the above calcium carbonate, and the pore is treated with nitric acid. The ammonium sulfate present, with the appropriate amount of nitric acid and calcium carbonate, is then processed according to the following formula: Am2SO4 + 2 HNO3 + CaCO2 ^ 2 AmNOs + + CaSO + CO2 + H2O. Thanks to the above process, Thorough disintegration of the calcium carbonate is avoided in order to obtain an ammonium sulphate solution adhering to it; Thus, both the apparatus and the method are simplified. The resulting solution can, depending on the circumstances, be separated from the calcium sulphate lost in the reaction and other insoluble products, and the constant amount of sulphate solvent therein can be evaporated to dryness or together with the above-mentioned process. tracks.
