Abstract
METODO PARA EXTRAER PENTOXIDO DINITROGENO (N SUB 2O SUB 5) DE SU MEZCLA EN ACIDO NITRICO, QUE CONSISTE EN PROPORCIONAR UNA SOLUCION DE LA MEZCLA EN UN SOLVENTE ORGANICO INERTE, REEXTRAER EL N SUB 2O SUB 5 DE LA SOLUCION EN UN FLUJO DE GAS PORTADOR CONTENIENDO OZONO, Y SUBSECUENTEMENTE CONDENSAR EL N SUB 2O SUB 5 FUERA DEL FLUJO DE GAS PONIENDOLO EN CONTACTO CON OTRO SOLVENTE ORGANICO INERTE. LA PRESENCIA DE OZONO SUPRIME LA DISOCIACION DEL N SUB 2O SUB 5 TRANSFERIDO AL FLUJO DE GAS EN TETROXIDO DINITROGENO (N SUB 2O SUB 4). EN UNA REALIZACION PREFERENTE LOS PASOS DE REEXTRACCION Y ABSORCION SE REALIZAN CONTINUAMENTE EN COLUMNAS DE ABSORCION Y REEXTRACCION ADYACENTES RESPECTIVAS CON SOLVENTE ORGANICO RECIRCULANDO A TRAVES DE CADA UNA.
