Abstract

Un proceso para la produccion de urea a partir de amoníaco y dioxido de carbono, que se hacen reaccionar a una presion elevada predeterminada en un reactor de síntesis apropiado (12), obteniendo una solucion acuosa que comprende urea, carbamato de amonio y amoníaco, recuperacion de carbamato y amoníaco a partir de dicha solucion acuosa a través de etapas de descomposicion del carbamato y depuracion térmica de amoníaco y dioxido de carbono así producidos, en un depurador (14) respectivo, su subsiguiente recondensacion a carbamato, en un condensador (16) respectivo, reciclado del carbamato al reactor de síntesis (12), siendo dichas etapas llevadas a cabo, junto con la reaccion de síntesis de urea, a sustancialmente la misma, presion elevada; el proceso comprende las etapas adicionales de: introducir O de pasivacion dentro del reactor de síntesis (12); recuperar desde dicho reactor (12) un efluente gaseoso que compende dioxido de carbono y amoníaco sin reaccionar y oxígeno de pasivacion; alimentar dicho efluente gaseoso desde el reactor de síntesis (12) a la base (14b) del depurador (14), para la pasivacion de al menos parte del interior he dicho depurador (14).
