Abstract

UNA CORRIENTE ENRIQUECIDA EN CRIPTON Y XENON SE OBTIENE DIRECTAMENTE DESDE LA COLUMNA DE BAJA PRESION (D2) EN UN PROCESO DE SEPARACION DE AIRE CRIOGENICO A BASE DE PONER EN DERIVACION (26,30) LAS POCAS BANDEJAS INFERIORES DE DICHA COLUMNA PARA REDUCIR LA RELACION DE LIQUIDO A VAPOR EN ELLAS. EL CRIPTON Y XENON SE CONCENTRAN EN EL COLECTOR MIENTRAS QUE LA MAYOR PARTE DEL METANO SE RETIRA CON UN PRODUCTO DE OXIGENO GASEOSO (24).
