Abstract

PROCEDIMIENTO CONTINUO DE DESTILACION POR VAPOR PARA EXTRACCION DE SOLVENTE PARA LA RECUPERACION DE HIDROCARBUROS AROMATICOS. SE PONE EN CONTACTO EN UNA ZONA DE EXTRACCION AGUA Y SOLVENTE PARA PRODUCIR UN SOLVENTE RICO EN AROMATICOS. SE CONDENSA UNA CORRIENTE QUE CONTIENE HIDROCARBUROS, AGUA Y VESTIGIOS DE SOLVENTE, DIVIDIENDOSE EL CONDENSADO EN UNA FASE RICA EN HIDROCARBUROS Y OTRA RICA EN AGUA. LA PRIMERA DE ELLAS SE LLEVA A UNA PRIMERA ZONA DE DESTILACION EN DONDE SE EXTRAEN COMPONENTES NO AROMATICOS. EL SOLVENTE RICO EN AROMATICOS SE HACE PASAR A UN REHERVIDOR, SIENDO EVAPORADO PARCIALMENTE, Y FORMANDO UNA CORRIENTE DE HIDROCARBURO Y VAPOR DE AGUA. SE EXTRAE LA PORCION LIQUIDA DE LA CORRIENTE ANTERIOR Y SE LLEVA A UNA SEGUNDA ZONA DE DESTILACION, OBTENIENDOSE EN ELLA TODOS LOS HIDROCARBUROS AROMATICOS DE LA CORRIENTE. SE HACE PASAR AGUA EVAPORADA POR ESTA SEGUNDA ZONA DE EVAPORACION PARA SEPARAR LOS AROMATICOS DEL SOLVENTE RICO EN ELLOS, OBTENIENDOSE UN SOLVENTE POBRE QUE SE RECICLA A LA ZONA DE EXTRACCION PRIMITIVA.
