Abstract

UN PROCESO PARA RECUPERAR OXIGENO (25) DE UN SISTEMA DE SEPARACION DE AIRE CRIOGENICO, EN EL QUE DATOS MEDIDOS EN LA ENTRADA Y SALIDA DE UN INTERCAMBIADOR DE CALOR LATENTE (22), Y DATOS MEDIDOS (30,32) DENTRO DE UNA COLUMNA SON COMPARADOS CON DATOS PRESELECCIONADOS DE MANERA QUE CUALQUIER DESVIACION ENTRE AMBOS, PUEDA SER UTILIZADA PARA PRODUCIR UNA SEÑAL QUE VARIARA LOS PARAMETROS DE ENTRADA DEL SISTEMA, HASTA QUE NO HAYA DESVIACION ENTRE LOS DATOS MEDIDOS Y LOS DATOS PREFIJADOS, ASEGURANDO ASI QUE EL SISTEMA OPERARA BAJO CONDICIONES OPTIMAS PRESELECCIONADAS.
