Description
Известен способ разложени природных (|)осфатов азотной кислотой с получением раствора, содержащего нитрат кальци и фосфорную кислоту , с последующим осаждением из этого раствора солей кальци в форме ннтрата кальци (вымораживанием ) и.чи в форме сульфата кальни (обменной реакцией с сульфатами щелочных металлов),There is a known method of decomposing natural (|) osfates with nitric acid to produce a solution containing calcium nitrate and phosphoric acid, followed by precipitation of calcium salts in the form of calcium nitrate (freezing) and chalium in the form of catalum sulfate (exchange reaction with alkali metal sulfates). ),
Отличите, сссбенностью описываемого способа вл етс использование раствора после отделени нитрата или сульфата кальци дл лолучепи копцентрироваппого азотнофосфорного удобрени .Distinguish between the described method is the use of a solution after the separation of calcium nitrate or sulphate for luchupi centrifugal nitrogen-phosphate fertilizer.
С этой целью фильтрат после отделени основного количества солей кальцн (отдел етс около 75% солей кальци от общего количества их в исходном растворе) }1асыщают нитрозпыми газами цехов производства азотной кислоты.To this end, the filtrate, after separating the main amount of calcium salts (about 75% of the calcium salts are separated from the total amount of them in the initial solution), is saturated with the nitrose gases of the nitric acid production workshops.
Полученный раствор, содержащий азотпую кислоту и фосфорную кислоту , а также не выкристаллизовавшийс при вымораживании нитрат кальци или питраты щелочных металлов , нейтрализуют газообразным аммиаком метОлЧом пульверизации.The resulting solution, containing nitric acid and phosphoric acid, as well as non-crystallized calcium nitrate or alkali metal nitrates upon freezing, is neutralized with gaseous ammonia by pulverization.
При этом, мину стадию упарки, за счет тепла процесса нейтрализации сразу по.тучают сухой сыпучий продукт - сложное концентрированное; азотпофосфориое удобрение, представл юнгее собою смесь аммиачной селитры, преципитата и нитратов кальцн и натри (кали ).At the same time, the stage of evaporation by the mine, due to the heat of the neutralization process, immediately dry dry bulk product - complex, concentrated; nitrogen-phosphorus fertilizer, representing a mixture of ammonium nitrate, precipitate and calcium and sodium (potassium) nitrate.

(exchange reaction with alkali metal sulphates) and separation of the precipitate from the solution by filtration, characterized in that, in order to obtain a dry granular product, pass the evaporation stage, the filtrate and after separating the main amount of calcium salts nitrous gases saturated with nitric acid production and the resulting concentrated solution containing nitric acid and phosphoric acid}, and are not freeze-crystallized calcium nitrate or nitrates of alkali metals, neutralized with gaseous ammonia.
