Abstract
EL CICLO COMPRENDE, PARA CADA UNO DE LOS TRES ADSORBEDORES (1 A 3), UNA FASE DE ADSORCION APROXIMADAMENTE ISOBARRA DE COCORRIENTE, UNA FASE DE DESORCION QUE COMPRENDE UNA ETAPA DE BOMBEO A L VACIO MEDIANTE UNA BOMBA DE VACIO (7) DE VELOCIDAD CONSTANTE Y DE FUNCIONAMIENTO CONTINUA, Y UNA FASE (C) DE REPRESURIZACION. DURANTE UNA REDUCCION DEL CAUDAL DE PRODUCCION, SE ELEVA LA PRESION MEDIA DE ASPIRACION DE LA BOMBA DE VACIO SOBRE LA DURACION DEL CICLO. APLICACION EN LA PRODUCCION DE OXIGENO IMPURO A PARTIR DE AIRE ATMOSFERICO.
