26 P-XYLENE SEPARATION FROM TERNARY XYLENE MIXTURE OVER SILICALITE-1 MEMBRANE: PROCESS OPTIMIZATION

摘要

Separation of para-xylene (p-xylene) from its isomers is an important operation in the petrochemical industry [1]. p-Xylene is the feedstock for the pure terephthalic acid (PTA) production, which in turn is used in the production of polyester resin and fibers. Therefore, it has the largest commercial market value among the three isomers of xylene.
