Abstract

Se revelan métodos y aparatos para la producción continua cuantitativa de amoníaco gaseoso a partir de urea, que incluyen los pasos consistentes en disolver urea en agua de manera de formar urea acuosa concentrada que contiene urea en una concentración de por lo menos el 77% en peso; introducir de manera continua la urea acuosa concentrada en un reactor; introducir de manera continua agua de suministro adicional separada en el reactor de manera de formar una mezcla reactiva acuosa de urea, calentar la mezcla reactiva acuosa de urea; y extraer de manera continua del reactor un producto en fase gaseosa que incluye amoníaco. También se revelan métodos y aparatos para la disolución, continua y discontinua, de la urea de manera de formar soluciones acuosas de urea.
