    11.3.2 Production of Ammonium Nitrate. Early production involved neutralization of concentrated aqueous ammonium hydroxide with nitric acid, followed by evaporation of much of the water and crystallization of the product. High capital, labor, and energy costs of this batch process have led to it being superseded by the Fauser continuous process
