Abstract

La presente invencion se refiere a metodos para recuperacion de urea y aceite a partir de un complejo urea/aceite, tambien a metodos para reciclar la urea recuperada. Dicho metodo comprende: a) eliminar el solvente de un complejo urea/aceite, en donde el complejo urea/aceite comprende urea, aceite y solvente, formando un complejo urea/aceite seco que esta sustancialmente libre de solvente; b) combinar el complejo urea/aceite seco con agua, formando una solucion de urea acuosa concentrada y una fase organica, formandose tambien una primera capa superior de aceite; c) eliminar la primera capa superior de aceite; d) separar la solucion de urea acuosa concentrada y la fase organica; e) anadir un acido a la solucion de urea acuosa concentrada; f) recoger una segunda capa de aceite formada despues de la etapa (d); y g) eliminar el agua de la solucion de urea acuosa concentrada, proveyendo por lo tanto una urea recuperada.
