Abstract
SE PRESENTA UN PROCESO EN EL CUAL SE RECUPERA METAXILENO DE UNA MEZCLA DE HIDROCARBONOS AROMATICOS C{SUB,8} MEDIANTE SEPARACION POR ABSORCION UTILIZANDO UN ZEOLITO Y INTERCAMBIADO CON SODIO COMO ABSORBENTE, EL PROCESO ES MEJORADO MANTENIENDO EL ABSORBENTE EN UNA ESTRECHA BANDA DE TEMPERATURA E HIDRATACION DURANTE EL PASO DE ABSORCION. EL NIVEL DE HIDRATACION ES TAL QUE EL ABSORBENTE TIENE UN LOI A 500 (GRADOS) C DE ENTRE 1.5% A 3.5% DE SU PESO Y LA TEMPERATURA DE ABSORCION ESTA ENTRE 100 (GRADOS) Y 150 (GRADOS) C. TANTO EL LITIO COMO EL SODIO SE INTERCAMBIAN EN EL ZEOLITO Y EN UNA CONFORMACION PREFERIDA.
