Abstract

UN PROCESO DE SEPARACION DE MEMBRANA Y DE PURIFICACION PARA LA SEPARACION DE UN COMPONENTE PERMEABLE DE OTRO, DONDE AMBOS COMPONENTES ESTAN CONTENIDOS EN UNA MEZCLA DE FLUIDO MULTI-COMPONENTE, COMO UNA FUNCION DINAMICA DE LAS DIFERENCIAS EN LAS RESPECTIVAS TASAS DE LOGRO Y DECRECIMIENTO DESDE UNA PERMEACION DE MEMBRANA EN ESTADO ESTABLE. EL PROCESO Y EL APARATO ESTAN IGUALMENTE BIEN EQUIPADOS PARA MEZCLAS DE FLUIDOS MULTI-COMPONENTES QUE SON LIQUIDOS O GASEOSOS.
