Abstract

EL PROCEDIMIENTO Y EL DISPOSITIVO SIRVEN PARA LA DESCOMPOSICION DE BAJA TEMPERATURA DE AIRE. EL AIRE (1) COMPRIMIDO, PURIFICADO Y REFRIGERADO SE GUIA AL MENOS PARCIALMENTE A LA ETAPA (3) DE PRESION DE UNA RECTIFICACION (2) DE DOS ETAPAS. EL LA ETAPA (4) DE PRESION INFERIOR SE EXTRAE UNA FRACCION (11) DE OXIGENO Y UNA FRACCION (10) QUE CONTIENEN NITROGENO COMO PRODUCTO. LA ZONA INFERIOR DE LA ETAPA DE PRESION INFERIOR SE ENCUENTRA EN UNION CON LA ZONA SUPERIOR DE LA ETAPA DE PRESION EN FORMA INTERCAMBIADORA TERMICA. EN FUNCIONAMIENTO ESTACIONARIO SE EXTRAE (11) ESENCIALMENTE EL LIQUIDO DE RECIRCULACION COMPLETO QUE FLUYE EN LA ETAPA (3) DE PRESION INFERIOR A PARTIR DE LA ZONA INFERIOR DE LA ETAPA DE PRESION REDUCIDA Y SE DERIVA (12) A UN RECIPIENTE (13) AMORTIGUADOR. EL LIQUIDO (16) A PARTIR DEL RECIPIENTE (13) AMORTIGUADOR SE EVAPORA EN INTERCAMBIO (6) TERMICO INDIRECTO CON GAS (5) DE CONDENSACION A PARTIR DE LA ZONA SUPERIOR DE LA ETAPA (3) DE PRESION PARCIALMENTE. CON ELLO EL VAPOR (17,18) GENERADO SE GUIA A LA ZONA INFERIOR DE LA ETAPA (4) DE PRESION REDUCIDA. LA PORCION QUE PERMANECE LIQUIDA SE ALIMENTA (17,12) DE NUEVO AL MENOS PARCIALMENTE EN EL RECIPIENTE (13) AMORTIGUADOR.THE PROCEDURE AND DEVICE SERVE FOR LOW AIR TEMPERATURE DECOMPOSITION. THE COMPRESSED, PURIFIED AND REFRIGERATED AIR (1) IS GUIDED AT LEAST PARTIALLY TO THE PRESSURE STAGE (3) OF A TWO-STAGE RECTIFICATION (2). IN THE LOWER PRESSURE STAGE (4) A FRACTION (11) OF OXYGEN AND A FRACTION (10) CONTAINING NITROGEN AS A PRODUCT ARE EXTRACTED. THE LOWER ZONE OF THE LOWER PRESSURE STAGE IS IN JOINT WITH THE UPPER ZONE OF THE PRESSURE STAGE IN A THERMAL EXCHANGER FORM. IN STATIONARY OPERATION, THE COMPLETE RECIRCULATION LIQUID FLOWS IN THE LOWER PRESSURE STAGE (3) FROM THE BOTTOM AREA OF THE REDUCED PRESSURE STAGE (12) IS DRAWN (12) TO A CONTAINER (13) . THE LIQUID (16) FROM THE CONTAINER (13) SHOCK ABSORBER EVAPORATES IN EXCHANGE (6) INDIRECT THERMAL WITH GAS (5) OF CONDENSATION FROM THE UPPER ZONE OF THE PARTIALLY PRESSURE STAGE (3). THEREFORE THE GENERATED STEAM (17,18) IS GUIDED TO THE LOWER ZONE OF STAGE (4) OF REDUCED PRESSURE. THE PORTION THAT REMAINS LIQUID IS FEEDED (17.12) AGAIN AT LEAST PARTIALLY IN THE CONTAINER (13) SHOCK ABSORBER.
