Abstract
Un proceso para la síntesis directa de urea a partir de amoníaco y dióxido de carbono con una resistencia aumentada a la corrosión, en la sección para la síntesis a alta presión, un paso de reacción en un reactor vertical (R) alimentado con al menos una corriente de dióxido de carbono fresco que contiene un agente para la estabilización y un paso de descomposición-separación de los reactivos no convertidos, en donde la mezcla de gas-líquido recolectada en el cabezal del reactor se separa en una corriente gaseosa y una corriente líquida alimentadas en la cola y el cabezal del separador, respectivamente.
