Abstract

EN ESTE PROCESO PARA LA PRODUCCION DE UREA, SE HACE REACCIONAR AMONIACO BASICAMENTE PURO Y DIOXIDO DE CARBONO EN UN ESPACIO DE REACCION (1) DEL QUE SALE UNA MEZCLA DE REACCION QUE SE DESTILA (2) PARA OBTENER UNA MEZCLA PARCIALMENTE PURIFICADA QUE SE ENVIA A UNA SECCION DE RECUPERACION DE UREA (3,4,7,8). EN LA SECCION DE RECUPERACION (3,4,7,8) SE OBTIENE UNA SOLUCION DILUIDA DE CARBAMATO QUE SE DESTILA (9) CON EL RECICLADO DE VAPORES DEL ESPACIO DE REACCION (1) TRAS SU CONDENSACION (6). ESTE PROCESO CONSIGUE UN ALTO RENDIMIENTO DE CONVERSION QUE REDUCE EL CONSUMO DE ENERGIA Y LOS COSTES DE FUNCIONAMIENTO.
