Abstract

LAS SUSTANCIAS AROMATICAS SE OBTIENEN A PARTIR DE HIDROCARBUROS QUE LAS CONTIENEN, POR DESTILACION EXTRACTIVA, UTILIZANDO UN DISOLVENTE SELECTIVO. ESTE DISOLVENTE SE INTRODUCE EN LA COLUMNA DE EXTRACCION A 40 (GRADOS) C MENOS DE TEMPERATURA QUE LA QUE REINA EN LA COLUMNA EN EL PUNTO DE ADMISION DEL DISOLVENTE. AL MISMO TIEMPO, EL VOLUMEN DE DISOLVENTE SE REDUCE EN UN 10 A 50 % CON RESPECTO AL VOLUMEN QUE CORRESPONDE A LA SELECTIVIDAD, ESTANDO DIRECTAMENTE RELACIONADOS ENTRE SI LA DISMINUCION DE TEMPERATURA Y LA DISMINUCION DE VOLUMEN.AROMATIC SUBSTANCES ARE OBTAINED FROM HYDROCARBONS THAT CONTAIN THEM, BY EXTRACTIVE DISTILLATION, USING A SELECTIVE SOLVENT. THIS SOLVENT IS INTRODUCED IN THE EXTRACTION COLUMN AT 40 (DEGREES) C LESS IN TEMPERATURE THAN THOSE THAT REIGN IN THE COLUMN AT THE ADMISSION POINT OF THE SOLVENT. AT THE SAME TIME, THE VOLUME OF SOLVENT IS REDUCED BY 10 TO 50% WITH REGARD TO THE VOLUME THAT CORRESPONDS TO SELECTIVITY, BEING DIRECTLY RELATED BETWEEN THE DECREASE IN TEMPERATURE AND THE DECREASE IN VOLUME.
