Abstract

Si descrive un ciclo di lavorazione per la separazione di C, aromatici (miscele di orto-, para -,meta-xilene ed etilbenzene) nel quale si effettua un primo smistamento della miscela in due correnti costituite, rispettivamente, da para-xilene ed etilbenzene la prima, e da meta- e orto-xilene la seconda, cui segue una separazione per rettifica della prima corrente, nel corso della quale si ottiene etilbenzene, a specifica, di testa, la seconda corrente essendo parimenti inviata ad una separazione per rettifica, così da ottenere a specifica, di coda: eventuali contenuti in C, possono ulteriormente essere rimossi per successiva distillazione.
