Abstract
En un proceso para la produccion de urea, se hacen reaccionar amoniaco substancialmente puro y dioxido de carbono en un espacio de reaccion (1), desde el cual sale una mezcla de reaccion sometida a separacion (2) para obtener una mezcla parcialmente purificada enviada a una seccion de recuperacion de urea (3, 4, 7, 8). A partir de la seccion de recuperacion (3, 4, 7, 8) se obtiene una solucion de carbamato diluido, la cual se somete a separacion (9) al reciclar los vapores hacia el espacio de reaccion (1) después de la condensacion (6). Este proceso logra un alto rendimiento de conversion con reducido consumo de energía y bajos costos de implementacion.
