Abstract
La invención es concerniente con un proceso para producir urea, en donde una solución de urea acuosa que sale de una zona de reacción de urea es alimentada a un agotador, en donde parte del amoníaco y dióxido de carbono no convertido es separada de la solución de urea acuosa, tal solución sale del agotador a una primera sección de recuperación y una o más secciones de recuperación seriales y es alimentada subsecuentemente a una o más secciones de concentración de urea, en donde la solución de urea que sale del separador es sometida a una expansión adiabática, creando así un vapor y un líquido, que son separados antes de que el líquido entre a una primera sección de recuperación y el vapor es condensado. La invención es concerniente además con una planta de urea que comprende un agotador y una primera sección de recuperación, en donde una válvula de expansión adiabática y un separador líquido/gas son provistos entre el agotador y la primera sección de recuperación.
