Abstract
Procedimiento para la preparación de urea a partir de dióxido de carbono y amoniaco por medio de un procedimiento de rectificación de urea, que comprende una torre de rectificación de alta presión y un condensador de alta presión, con lo que se forma una solución de síntesis de urea, y en el que el vapor de agua condensado que se forma durante la rectificación a alta presión de la solución de síntesis de urea se usa para la descomposición a media presión del carbamato de amonio en la solución de síntesis de urea. caracterizado porque se usa una combinación del vapor de agua condensado y el vapor de agua A, que se forma en el condensador de alta presión, para la descomposición a media presión, siendo el condensador de alta presión un condensador sumergido. La presente también se refiere a un procedimiento para mejorar una planta de urea que comprende un procedimiento de rectificación térmica.
