Separation of p-xylene from xylene isomer mixtures within a single stage porous batch cooling crystallizer
Abstract: Crystallization based separation of p-xylene from its isomer mixtures were mostly accomplished in stirring crystallizers, suspension crystallizer and scrapping crystallizer followed by centrifugation. In this work, separation process for p-xylene, where both crystallization and separation of p-xylene in a single batch crystallizer, was performed. Upon cooling, p-xylene, which has the higher melting point than other xylene isomers (o-xylene and m-xylene), crystallizes first. Xylene mixture samples were crystallized at a lower …
