Abstract

Un proceso para la produccion de urea se hacen reaccionar amoniaco substancialmente puro y dioxido de carbono en un espacio de reaccion principal (R-1) a partir del cual sale una mezcla de reaccion que se somete a depurado para obtener una mezcla parcialmente purificada que se envía a una seccion de recuperacion de urea (3). A partir de esta seccion (3) se obtiene una solucion de carbamato diluida que se recicla hacia un espacio de reaccion auxiliar (R-2), en donde el carbamato residual se convierte en urea. Este proceso logra un rendimiento de conversion promedio alto con un consumo de energía reducido.
