Abstract

PROCEDIMIENTO PARA LA OBTENCION DE UREA A PARTIR DE AMONIACO Y DIOXIDO DE CARBONO A TEMPERATURA Y PRESION ELEVADAS. CONSISTE EN LA REACCION DE DIOXIDO DE CARBONO Y AMONIACO A CARBAMATO AMONICO EN UNA ZONA DE REACCION; SEGUIDA DE LA TRANSFORMACION DE UNA PARTE DEL CARBAMATO AMONICO EN UREA CON LO QUE SE FORMA UN EFLUENTE EN LA ZONA DE REACCION CONSTITUIDO POR UREA, CARBAMATO AMONICO Y AMONIACO; DESCOMPOSICION DE UNA PARTE DEL CARBAMATO AMONICO CONTENIDO EN UNA CORRIENTE DE PRODUCTO UREA Y CARBAMATO AMONICO EN UNA ZONA DE SEPARACION DE MATERIAS VOLATILES; Y SEPARACION DE LOS MATERIALES VOLATILES AMONIACO Y DIOXIDO DE CARBONO. LA TRANSFORMACION DE CARBAMATO EN UREA EN LA ZONA DE REACCION SE CONTINUA HASTA QUE SE FORMA EL 50% DE LA CANTIDAD DE UREA QUE SE PODRIA OBTENER EN EL EQUILIBRIO, EN LAS CONDICIONES DE REACCION.
