Description
Изобретение относите к производству аммкачной селитры и может быть использойаио дл ее стабилизации (повышени yctoJ HBOcTH к фазовым превращени м).The invention relates to the production of ammonium nitrate and can be used to stabilize it (increase yctoJ HBOcTH to phase transformations).
Известен способ стабилизации гршул амкшачной селитры путем введени в раствор нитрата аммони , сульфата аммони , моно- н дааммоннйфосфата и борюй кислоты 1.There is a known method of stabilizing grishul ammonium nitrate by introducing ammonium nitrate, ammonium sulfate, mono daammonium phosphate and boric acid 1 into the solution.
Недостаток зтого способа состоит в необко« димостН использовани борной кислоты, что удорожает продукт.The disadvantage of this method is the lack of boron acid utilization, which increases the cost of the product.
Известен также способ стабнлнзашш гранул аммначной селитры путем введени в ее состав сульфата аммоннЯ, Ш1аммон1Ц(фосфата и борео держащей добаВкн (2.There is also known a method for the stabilization of granules of ammonium nitrate by introducing ammonium sulfate, ammonium sulfate (phosphate and boreo-containing additive (2.
Недостатком такого способа вл етс т юпьзовани дорогой н де ищктной борсодержащей цобавкн буры. Кроме того, npowocTb гранул продукта Колеблетс в.широких пределах от 0,2 да 1,4 кг/гранул.The disadvantage of this method is the use of expensive n-boron boron-containing mineral borax. In addition, the npowocTb granules of the product Koleblets in a wide range from 0.2 to 1.4 kg / granules.
Цель изобретени - удешевление продукта и noBbgaeffiie однородности его фанул по про «юсти.The purpose of the invention is to reduce the cost of the product and the noBbgaeffiie homogeneity of its fan in terms of efficiency.
Это достигаетс тем, что в качестве борсодар жащей добавки используют борсодержшцую рудуThis is achieved by using boron-containing ore as a boring agent
9 состав которой вход т сосди11ени магни и кремни .9 the composition of which includes the deposition of magnesium and silicon.
При этом количество соединений бора в борсодержащей руде составл ет 18-30 всс,% BjOj, 15-18 вес.% Мдб, 10-13 вес.% кремни .Moreover, the amount of boron compounds in boron-containing ore is 18-30 Vss,% BjOj, 15-18 wt.% MDb, 10-13 wt.% Silicon.
Пример 1. Смесь водных растворов кислот , содер н Ш(ую 778 кг азотной, 4,15 кг фосфорной и 0,74 кг серной кислоты, нейтрализуют газообразным аммиаком до получени раствора аммиачной селитры с концентрацией 92;.Example 1. A mixture of aqueous solutions of acids containing nth III (778 kg of nitric acid, 4.15 kg of phosphoric acid, and 0.74 kg of sulfuric acid are neutralized with gaseous ammonia to obtain a solution of ammonium nitrate with a concentration of 92 ;.
Затем раствор упаривают до содержани 0,5% Bjiani. В полученный плав добавл ют 6,7 кг тонкоизмельченной борсодержащей руды и смесь гранулированию. Полученные гранулы аммиачной селитры содержат 0,1% сульфатаThen the solution is evaporated to a content of 0.5% Bjiani. 6.7 kg of finely ground boron-containing ore and the granulation mixture are added to the resulting melt. The obtained granules of ammonium nitrate contain 0.1% sulfate
аммонИ , 0,3% фосфата аммони (в пересчете на PjOj), 0,3% НзВОз, 0,1% МдО и 0,1% Si. Прочность гранул колеблетс от 0,65 до 1,4 кг/ 1ранулу.ammonium, 0.3% ammonium phosphate (in terms of PjOj), 0.3% NWO3, 0.1% MgO and 0.1% Si. The strength of the granules ranges from 0.65 to 1.4 kg / 1ranula.
П р н М е р 2. 1 кг сульфата аммони ,PR n M e p 2. 1 kg of ammonium sulfate,
6,5 кг аммофоса, кг мелкоизмепьченной борсодержгшей руды раствор ют в воде с одновременной аммонизацией при температуре бОС. Получеиный раствор смешивают с 1071 кг 92%Hbro pacTBdpaакшиачной селитры и упартают до содержани 0,5% влаги. liojiyieraijiib сшсъ гранулируют. Прочность гранул крлеЙлеМ от 0,8 до 13 кг/гранулу.,.6.5 kg of ammophos, kg of finely divided boron-containing ore are dissolved in water with simultaneous ammonization at bOS. The resulting solution is mixed with 1071 kg of 92% Hbro pacTBdra-axiom nitrate and evaporated to a content of 0.5% moisture. liojiyieraijiib shhh granulate. The strength of the granules is from 0.8 to 13 kg / granule.,.
Использование добавки борсоДержащей руДы позвол ет удешевить стабилизацию аммиачной селитры, а введение в ее состав соедаше1шй Магни и кремни способствует снижению пределов колебани пррчности гранул до 0,65-1,4 кг/гра У У , ..,- - .. . . . The use of an additive of borson-keeping enzyme allows to reduce the cost of stabilizing ammonium nitrate, and the introduction of magnesium and silicon in its composition helps to reduce the limits of fluctuation of the prurity of the granules to 0.65-1.4 kg / gram V, .., - - ... . .
