Abstract
Process for obtaining ammonium nitrate, characterized in that it is particularly the reaction of nitric acid with a concentration of at least 60%, with anhydrous ammonia, hot and pressure, with recovery of heat of reaction to obtain a nitrate solution ammonium at about 95% concentration or more, where the neutralization is carried out in a reaction zone maintained at a pressure ranging between 1 and 4 Kg/cm2 in its upper part and at a temperature comprised between 145 and 160ºC to avoid an evaporation of the reaction mixture.
