Abstract
SE DESCRIBE UN METODO PARA SEPARAR CRIOGENICAMENTE UNA MEZCLA DE GASES ATMOSFERICOS DENTRO DE UNA COLUMNA DE DESTILACION. DE ACUERDO CON EL METODO, LAS FASES LIQUIDAS Y GASEOSAS DE LA MEZCLA DE GASES ATMOSFERICOS QUE DEBEN SEPARARSE, SON PASADAS CONTRA-CORRIENTE A TRAVES DE UNA EMPAQUETADURA ESTRUCTURADA. LA COLUMNA ES ACCIONADA A UNA PRESION MAYOR DE 2 BARS Y A UN CAUDAL DE VAPOR MENOR QUE EL CAUDAL DE VAPOR CRITICO AL CUAL LA COLUMNA SE LLENA, Y QUE VARIA CON EL CAUDAL DE LIQUIDO. EL CAUDAL DE VAPOR CRITICO Y MINIMO CON LOS CUALES SE LLENA LA COLUMNA, SE ESTABLECEN DE ACUERDO CON DATOS DE EXPERIMENTACION PARA LA UTILIZACION MAXIMA DE LA COLUMNA EN TERMINOS DE VOLUMEN DE EMPAQUETAMIENTO O CAPACIDAD DE TRATAMIENTO DE LA COLUMNA. LA REALIZACION DE LA EMPAQUETADURA ESTRUCTURADA MEJORA SORPRENDENTEMENTE CON EL INCREMENTO DE LA PRESION. POR CONSIGUIENTE, LAS COLUMNAS DE UNA FUNCION DADA (EJ. CAPACIDAD) PUEDEN SER PRODUCIDAS UTILIZANDO UN VOLUMEN MENOR DE EMPAQUETADURA ESTRUCTURADA QUE EL QUE HASIDO PREDICHO TEORICAMENTE. ADICIONALMENTE, EL CUMPLIMIENTO DE LA SEPARACION EN TERMINOS DE HETP, SE INCREMENTA CON EL AUMENTO DE LA PRESION YA QUE LA ALTURA EN TECNICAS PREVIAS DE LA EMPAQUETADURA ESTRUCTURADA PUEDE UTILIZARSE PARA OBTENER UNA SEPARACION PARTICULAR.
