- Technical Characteristics
Introduction
As a para-xylene (PX) recovery unit of integrated aromatic complex, simulating moving bed (SMB) adsorption process developed by Sinopec is utilized to obtain high purity PX product from the feed of a mixed C8 aromatic isomers, while the obtained raffinate is sent to re-establish an equilibrium concerntration of PX through a xylene isomerization unit. Compared with the crystallization, the adsorption process is featured with much higher PX yield per pass.
