Abstract

UN PROCESO Y SISTEMA DE ABSORCION OSCILANTE DE PRESION PARA LA SEPARACION DE AIRE QUE CONSTA DE UN RECIPIENTE DE ALMACENAMIENTO DE PRODUCTO DE NITROGENO DE VOLUMEN VARIABLE QUE SE CONTROLA PARA DETERMINAR LAS VARIACIONES EN LA DEMANDA DE PRODUCTO DEL USUARIO. EL CICLO DE PROCESAMIENTO Y LOS PASOS DE PROCESAMIENTO INDIVIDUALES SE AJUSTAN DURANTE LOS PERIODOS DE DEMANDA REDUCIDA PARA MANTENER UNA PUREZA Y PRESION DE PRODUCTO DESEADA, ALCANZANDOSE UNA REDUCCION DE ENERGIA Y AHORRO DE ENERGIA BAJO CONDICIONES DE DEMANDA REDUCIDA.
