Similar moving bed xylene blend head-end process and separated method of the aromatic compound which includes about additional xylene strange character chemical engineering

摘要

It is something regarding the separated method of the aromatic compound which features similar moving bed xylene blend head-end process and that about additional xylene strange character chemical engineering furthermore is included in the aromatic compound separated method this invention, the sulfonic run process which is non aromatic removal process, benzene/toluene cutoff process, aromatic cutoff process and selective disproportionation process of toluene, about trance alkyl chemical engineering, including about similar moving bed para - xylene partition stage and xylene strange character chemical engineering, utilizing the similar moving bed adsorption chromatography. As for separated method of the aromatic compound of this invention, it is possible to improve productivity of para - xylene and benzene to remarkable with the side of entire process in comparison with the partition stage of the former aromatic compound.
