Design basics of compact unit for obtaining ammonium nitrate with nanoporous structure

Abstract

The current work describes the algorithm for obtaining porous ammonium nitrate granules in granulation plants using devices with different fluidized bed configurations. We present brief theoretical foundations for calculating the main equipment of the granulation plant. We develop and propose the design of individual units for the sequential implementation of the main stages of ammonium nitrate modification to obtain a nanostructured porous surface layer. We assess the ammonium nitrate nanoporous structure quality and show further ways to improve the technology. Current work also pays attention to methods for ensuring the necessary specific quality indicators of porous ammonium nitrate by choosing the optimal technological mode of the unit operation and the design characteristics of the main equipment.
