Abstract
SE PRESENTA UN PROCESO PARA LA SEPARACION DE HF DE COMPUESTOS ORGANICOS QUE CONSISTE EN HACER PASAR UNA MEZCLA DE HF Y COMPUESTOS ORGANICOS A TRAVES DE UNA COLUMNA O LECHO QUE CONTIENE UN POLIMERO QUE SORBE EL HF DEJANDO UNA CORRIENTE ORGANICA ESENCIALMENTE PURA. EL HF SE PUEDE RECUPERAR DEL POLIMERO, O SE PUEDEN RECUPERAR LOS COMPUESTOS ORGANICOS CON UNA CONCENTRACION DE HF REDUCIDA. EL HF Y LOS COMPUESTOS ORGANICOS PUEDEN FORMAR UNA MEZCLA AZEOTROPICA O TIPO AZEOTROPO.
