Abstract

The article studies the process of obtaining carbonate-ammonium nitrate (CAN) based on the mixing of melt ammonium nitrate (NH4NO3) with chalk (СаСО3) and ammonium sulfate (NH4)2SO4). For the granulation of nitrate-sulfate-carbonate melt the prilling method is applied using a granulation tower. Determined the composition and properties of new types of fertilizers. It is shown that with the ratio NH4NO3 : СаСО3 : (NH4)2SO4 = 100 : 24 : 1 the product contains 28,03% N, SO3 – 0,50%, 10% СаО and has a granule strength of 6,03 MPa, which is much higher than the strength of pure NH4NO3 granules (1,32 MPa). Porosity and absorption of pure AN granules is 22,0% and 4,82 g. With an increase in the proportion of chalk and ammonium sulfate to the NH4NO3 : СаСО3 : (NH4)2SO4 = 100 : 24 : 1 ratio, the porosity and absorbency of the LAN granules is 6,11% and 2,57g, respectively. It was revealed that the use of the (NH4)2SO4, СаСО3 additive in the NH4NO3 melt at a mass ratio of NH4NO3 : СаСО3 : (NH4)2SO4 = from 100 : 2 : 0,5 to 100 : 58 : 2 allows to increase the strength and temperature of the onset of decomposition of the nitrate granules by 2-6,7 and 1-1,3 times and reduce the porosity by 2,7-4,8 2 times.

生产以白垩、硝酸铵、硫酸铵为基础的石灰硝酸铵
本文研究了熔融硝酸铵(NH4NO3)与白垩(СаСО3)和硫酸铵(NH4)2SO4混合制备碳酸硝酸铵(CAN)的工艺。对硝酸-硫酸盐-碳酸盐熔体的造粒,采用造粒塔造粒法。确定了新型肥料的组成和性能。结果表明,当NH4NO3: СаСО3: (NH4)2SO4 = 100: 24: 1时,产品含N 28.03%, SO3 - 0,50%, 10% СаО,颗粒强度为6.03 MPa,远高于纯NH4NO3颗粒的强度(1,32 MPa)。纯AN颗粒的孔隙率和吸收率分别为22.0%和4.82 g。随着白垩粉和硫酸铵与NH4NO3: СаСО3: (NH4)2SO4 = 100: 24: 1比例的增加,LAN颗粒的孔隙率和吸光度分别为6.11%和2.57 g。结果表明,在NH4NO3: СаСО3: (NH4)2SO4 = 100: 2:0,5 ~ 100: 58: 2的质量比下,在NH4NO3熔体中加入(NH4)2SO4, СаСО3添加剂,可使硝酸颗粒的分解强度和开始分解温度分别提高2-6,7和1-1,3倍,孔隙率降低2,7-4,8 2倍。
