Abstract
LA INVENCION ES UNA MEJORA EN LOS MEDIOS DE REFLUJO DEL NITROGENO LIQUIDO CAPAZ DE PERMITIR EL FUNCIONAMIENTO DE CICLOS DE SEPARACION DE AIRE DE CALDERA CONVENCIONAL, DOBLE Y TRIPLE A ELEVADAS TEMPERATURAS. LA MEJORA COMPRENDE: A) EL INTERCAMBIO DE CALOR (148) DE UNA PARTE (162) DEL FONDO DEL OXIGENO LIQUIDO DE LA COLUMNA DE PRESION INFERIOR (116) CONTRA UNA CORRIENTE DE VAPOR DE NITROGENO (146) SEPARADA DE LAS COLUMNAS DE PRESION MAYOR O MENOR (110, 116) O DERIVADA DEL PRODUCTO DEL NITROGENO GASEOSO (152), EN DONDE ANTES DE DICHO INTERCAMBIO DE CALOR, SE AJUSTA LA PRESION DEL FONDO DEL OXIGENO LIQUIDO O DE LA CORRIENTE DE VAPOR DE NITROGENO O DE AMBOS EN UNA MAGNITUD EFECTIVA DE FORMA QUE EXISTA UNA DIFERENCIA ADECUADA DE TEMPERATURAS ENTRE EL FONDO DEL OXIGENO LIQUIDO Y LA CORRIENTE DE VAPOR DE NITROGENO DE MANERA QUE DESPUES DEL INTERCAMBIO DE CALOR EL NITROGENO SEA COMPLETAMENTE CONDENSADO Y LA PARTE DEL FONDO DEL OXIGENO LIQUIDO ESTE AL MENOS PARCIALMENTE VAPORIZADA; B) LA UTILIZACIONDE NITROGENO CONDENSADO COMO REFLUJO EN AL MENOS UNA DE LAS DOS COLUMNAS DE DESTILACION; Y C) EL CALENTAMIENTO DEL OXIGENO VAPORIZADO PARA RECUPERAR LA ENERGIA DE REFRIGERACION.
