Abstract:
With the p-xylene, o-xylene simple eutectic system, the purification process of organic materials in an inclined column crystallizer at total reflux and steady state was investigated. The results indicate that inclined column crystallizer has strong adaptability for purifying p-xylene, the product purity can easily exceed 99.9% at the range of feed composition among 65.0%-85.0% and internal stirring speed among 6-10 r/min, the axial dispersion model satisfactorily explains the concentration distribution profile in inclined column crystallizer.
