Description
аммиачной селитры при 95-114С. К полученному концентрированному раствору при перемешивании добавл ют мочевину в весовом соотнесении мочевины к промстокам 1:(2-3). Готовый продукт вл етс жидким азотным удобрением, содержащем, г/л: . 350,0; СО (NH2 304 , О , МО О ,442 ammonium nitrate at 95-114C. With the stirring, urea is added to the concentrated solution obtained in a weight ratio of urea to promoters 1: (2-3). The finished product is a liquid nitrogen fertilizer containing, g / l:. 350.0; CO (NH2 304, O, MO O, 442
Ni 0,1; общее содержание азота 27%, рН 6,5-7,0. Температура кристаллиза ции 10°С.Ni 0.1; total nitrogen content of 27%, pH 6.5-7.0. The crystallization temperature is 10 ° С.
Упаривание растворов до концентрации менее 600 г/л экономически невыгодно из-за низкого содержани азота в полученных жидких удобрени х .Evaporation of solutions to a concentration of less than 600 g / l is economically disadvantageous due to the low nitrogen content in the resulting liquid fertilizers.
Дальнейшее упаривание промстоков (до концентрации вьл е 600-700 г/л аммиачной селитры) вл етс нецелесообразным , так как одновременно с увеличением концентрации аммиачной селитры в упаренном растворе увеличиваетс содержание примесей и коагулируетс та органическа , котора находитс в исходных промстоках в растворенном состо нии и, вследствие этого, не может быть отделена методом отстаивани .Further evaporation of effluent (to a concentration of 600-700 g / l of ammonium nitrate) is impractical, since simultaneously with an increase in the concentration of ammonium nitrate in one stripped solution, the content of impurities increases and the organic matter that is present in the dissolved effluent coagulates and coagulates. As a result, it cannot be separated by settling.
Кроме того, при концентраци х аммиачной селитры вь ие 600-700 г/л происходит кристаллизаци упаренных промстоков в процессе дальнейшей их переработки, что нежелательно, так как это в свою очередь усложн е обслуживание технологического оборудовани и усиливает позкаро-и взрывоопасные свойства селИтЕМ.In addition, at concentrations of ammonium nitrate of 600–700 g / l, evaporation of the evaporated industrial effluent occurs during further processing, which is undesirable, since this in turn complicates the maintenance of the process equipment and enhances the posit and explosive properties of ITEM.
С целью снижени температуры кри таллизации упаренных промстоков и увеличени содержани в них азота, близкого к содержанию его в сухой г1ммиачной селитре, упаренный раство промстоков с содержанием аммиачной.In order to reduce the temperature of crystallization of the stripped industrial wastes and increase the nitrogen content in them, which is close to its content in the dry g1 mnium nitrate, one stripped of the industrial wastes with ammonia content.
селитры 600-700 г/л смешивают с мочевиной , который вл етс азотсодержащим компонентом и одновременно агентом, понижаюгцим температуру кристаллизации жидкого удобрени до минус .600-700 g / l nitrate is mixed with urea, which is a nitrogen-containing component and at the same time an agent, lowering the crystallization temperature of liquid fertilizer to minus.
Оптимальным соотношением мочевины к упаренному раствору, при котором создаютс наиболее благопри тные услови дл получени жидкого азотного удобрени с высоким содержанием азота и с низкой температурой кристаллизации, вл етс соотношение 1: (2-3).The optimal ratio of urea to one stripped off solution, which creates the most favorable conditions for obtaining liquid nitrogen fertilizer with a high content of nitrogen and a low crystallization temperature, is 1: (2-3).
В результате получают жидкое азотное удобрение с микроэлементами молибдена и никел , содержащие 2532% азота в аммиачной, нитратной и амидной формах.The result is a liquid nitrogen fertilizer with trace elements molybdenum and nickel, containing 2532% nitrogen in the ammonium, nitrate and amide forms.
