Abstract
LA INVENCION TRATA DE UN PROCEDIMIENTO Y UN DISPOSITIVO EN EL CUAL EL AIRE ES COMPRIMIDO A UNA PRESION INICIAL EN UN PRECOMPRESOR (1), POSTERIORMENTE ES ENFRIADO, PURIFICADO Y CALENTADO DE NUEVO. UN INTERCAMBIADOR DE CALOR (2) SE ENCARGA DEL ENFRIAMIENTO Y RECALENTAMIENTO SIMULTANEOS. LA SEPARACION DEL NITROGENO SE LLEVA A CABO EN UNA UNIDAD DE SEPARACION (4) QUE ESTA FORMADA POR UN GRAN NUMERO DE SEPARADORES DE MEMBRANA. EL CONCENTRADO, ENRIQUECIDO CON NITROGENO, DEL ULTIMO PASO ES PUESTO NUEVAMENTE EN CIRCULACION POR EL LADO DE SUCCION DEL PRECOMPRESOR (1). EL NITROGENO SEPARADO ES COMPRIMIDO A LA PRESION PREVISTA EN UN COMPRESOR FINAL (6) CONECTADO A LA UNIDAD DE SEPARACION (4). UN INTERRUPTOR MANOMETRICO (8) CONTROLA EL SISTEMA DE TAL MANERA QUE, AL ARRANCAR, EL COMPRESOR FINAL (6) NO SE CONECTA HASTA QUE NO SE HA ALCANZADO LA PRESION DE TRABAJO DE LA UNIDAD DE SEPARACION (4). HASTA ESE MOMENTO, EL GAS SUMINISTRADO POR LA UNIDAD DE SEPARACION (4) ES RECIRCULADO PARCIALMENTE AL PRECOMPRESOR (1). TAMBIEN TIENE LUGAR UNA RECIRCULACION DEL NITROGENO DE DERRAME DESDE EL COMPRESOR FINAL (6) HASTA EL PRECOMPRESOR (1).
