Abstract
EN UN PROCESO MEJORADO PARA LA PREPURIFICACION DE UNA CORRIENTE ASCENDENTE DE AIRE DE SU INTRODUCCION EN UNA UNIDAD SEPARADORA DE AIRE CRIOGENICA, EL VAPOR DE AGUA Y EL DIOXIDO DE CARBONO SON EXTRAIDOS DEL AIRE MEDIANTE UN PROCESO DE ABSORCION GIRATORIA DE PRESION (AGP) QUE UTILIZA UN ABSORBENTE QUE TIENE UNA CAPA INICIAL DE ALUMINIA ACTIVADA QUE TIENE DE UN 70% A UN 100% POR VOLUMEN DEL LECHO CON LA CAPA QUE QUEDA, SI SE ENCUENTRA PRESENTE, SIENDO UNA ZEOLITA APTA. LAS PARTICULAS DE ABSORBENTE, SOBRE TODO LA ZEOLITA, TIENEN UN TAMAÑO DE PARTICULA NO SUPERIOR DE 2 MM. SE UTILIZAN DOS LECHOS (A,B) O ABSORBENTES. AL TIEMPO QUE UN LECHO PRODUCE AIRE PURIFICADO, EL OTRO ES EXPUESTO A LA ATMOSFERA Y DESPUES SE PURGA CON UN GAS LIBRE DE IMPUREZAS PARA REGENERARLO. AMBOS PASOS DE REGENERACION CONSISTEN EN QUE EL GAS FLUYA A TRAVES DEL LECHO CONTRACORRIENTE AL FLUJO DE AIRE DURANTE LA FASE DE PRODUCCION. DESPUES DE PURGADO, EL LECHO QUE ESTA SIENDO REGENERADO SE REPRESURIZA ALIMENTANDOLO (COMO SU FINAL DE GAS DE PRODUCTO) CON GAS DE PRODUCTO DESDE EL OTRO LECHO.
