Description
Изобретение относитс к способам полу-чени минеральных удобрений и может быть использовано на калийных комбинатах производ щих бесхлорные и другие калийные удобрени .The invention relates to methods for the production of mineral fertilizers and can be used in potash plants producing chlorine-free and other potash fertilizers.
Известен способ получени бесхлорного азотсодержащего калийного удобрени в виде двойной соли сульфата кали аммони 5K2,(N Н)., 304 путем конверсии хлористого кали сульфатом аммо- ни в водной среде с отделением на первой стадии двойной соли и затем NN4после выпаривани фильтрата .A method is known for producing chlorine-free nitrogen-containing potassium fertilizer as the double potassium salt of ammonium sulfate 5K2, (N, N), 304 by converting potassium chloride to ammonium sulfate in an aqueous medium, separating the double salt in the first stage and then NN4 after evaporation of the filtrate.
Недостатком известного способа aensiетс неполное извлечение товарного ups дукта (78%), а также необходимость выпаривать большие количества агрессивного раствора содержащего N Н4СВ.The disadvantage of this method is the incomplete extraction of product ups of the product (78%), as well as the need to evaporate large quantities of an aggressive solution containing N H4CB.
Наиболее близким к предлагаемому по технической сущности и достигаемому ре- зультату вл етс способ получени бесхлорного азотсодержащего калийного удобрени путем канверсии хлористого кали сульфатом аммони в насыщенном солевом растворе сульфата кали - аммони иThe closest to the proposed technical essence and the achieved result is a method for producing chlorine-free nitrogen-containing potassium fertilizer by canversion of potassium chloride with ammonium sulfate in a saturated salt solution of potassium sulfate - ammonium and
NHiCE с нагревом суспензии до 90 С в последующим охлаждением ее при переме- щивании. Разделение конечных продуктов реакдии ведут методом флотации с помощью реагента собирател сол нокислого октадециламина.NHiCE with the suspension heated to 90 ° C, followed by its cooling with stirring. Separation of the final reaction products is carried out by flotation with the help of a collector of hydrochloric octadecylamine.
В камерный продукт извлекаетс 95% Oj и 18% К НдС при содержании в нем 89,5% 1O,5%NH4CB 2}95% Oj and 18% K of VDS are recovered into the chamber product at a content of 89.5% 1O, 5% NH4CB 2}.
Недостатком известного способа вл етс наличие большого содержани N И С0 в бесхлорном удобрении и необходимость применени дефинитного, токсичного и дорогосто щего собирател .The disadvantage of the known method is the presence of a high content of N and C0 in chlorine-free fertilizer and the need to use a definitive, toxic and expensive collector.
Целью изобретени вл етс увеличение степени извлечени двойной солиThe aim of the invention is to increase the degree of extraction of the double salt.
Од. А готовый продукт и удешевление процесса. Odd And the finished product and cheaper process.
Поставленна цель дос1игаетс описываемым способом получени бесхлорного калийного азотсодержащего удобрени в е1ще двойной соли сульфата кали -аммони (NH4)2S04J путем конверсии КСВ сульфатом аммони по реакцииThe goal is achieved by the described method of producing chlorine-free potassium nitrogen-containing fertilizer more than double potassium-ammonium sulphate double salt (NH4) 2S04J by converting the CWS with ammonium by the reaction
