Abstract
PROCEDIMIENTO PARA LA OBTENCION DE NITROGENO DEL AIRE O GASES CON CONTENIDO DE NITROGENO MEDIANTE ADSORCION POR CAMBIO DE PRESION EN TAMICES DE MOLECULAS DE CARBONO. PROCEDIMIENTO PARA LA OBTENCION DE NITROGENO DEL AIRE O GASES CON CONTENIDO DE NITROGENO MEDIANTE LA ADSORCION Y DESORCION POR CAMBIO DE PRESION EN DOS ADSORBENTES ALTERNATIVOS, QUE PRESENTAN TAMICES MOLECULARES DE CARBONO, EN DONDE UN ADSORBENTE ES RECORRIDO POR AIRE DE MANERA QUE ADSORBE EL OXIGENO Y SE OBTIENE EL NITROGENO EN FORMA ENRIQUECIDA, Y QUE SIMULTANEAMENTE EL OTRO ADSORBENTE ES REGENERADO MEDIANTE DISMINUCION DE LA PRESION. EN UNA PRIMERA CAPA DE FILTRO DE MOLECULAS DE CARBONO (EN EL LADO DE ENTRADA DE AIRE) DE LOS DOS ADSORBENTES, QUE REPRESENTA EL 1/20 HASTA 1/2 DE LA CAPA DE TAMIZ MOLECULAR DE CARBONO TOTAL, SE APLICA UN TAMIZ MOLECULAR DE CARBONO (A), QUE SIMULTANEAMENTE SIRVE PARA LA RECEPCION DE LA HUMEDAD RESIDUAL Y PARA LA SEPARACION DE GASES, Y EN UNA SEGUNDA CAPA DE TAMIZ MOLECULAR DE CARBONO (EN EL LADODE SALIDA DE AIRE) SE APLICA UN TAMIZ MOLECULAR DE CARBONO B, QUE SIRVE EXCLUSIVAMENTE PARA LA SEPARACION DE GASES, Y EL TAMIZ MOLECULAR DE CARBONO A TIENE UN VOLUMEN RELATIVO DE 3,0 A 3,4 Y EL TAMIZ MOLECULAR DE CARBONO B UN VOLUMEN RELATIVO DE 2,3 A 2,95.
