Abstract

Un procedimiento para eliminar el cloruro de vinilo del amoniaco reciclizado en la producción de etilendiamina a base de amoniaco y bicloruro de etileno, caracterizado por el hecho de que el amoniaco obtenido de la primera dilatación se absorbe en una primera torre de presión hermética con una solución amoniacal acuosa y en una segunda torre a presión atmosférica, con agua, y por último se vuelve a usar, mientras el cloruro de vinilo se deja escapar por la parte superior de la segunda torre.
