Technological Calculation of Granulation Equipment for the Production of Ammonium Nitrate with a Nanoporous Structure: Algorithm and Software Implementation

Abstract

The work is devoted to developing the optimal design for granulation equipment aimed to modify ordinary ammonium nitrate with the subsequent obtaining of nanoporous structure. We present the fundamental technological calculation of vortex-type granulation equipment with various configurations of a vortex fluidized bed (including a combined one). We introduce an algorithm for deriving the optimal design of a vortex granulator able to provide a developed nanoporous structure of ammonium nitrate granules and their specific properties. The need for an optimization calculation of granulation equipment using computer modeling was substantiated. We demonstrate computer modeling and automated computation in the general method of engineering calculation of granulation equipment. The electron microscopy results of porous ammonium nitrate samples are presented, and the pore structure features (size, configuration, specific porous volume, etc.) are analyzed.
