PTA is a lower product of petroleum. Petroleum produces light gasoline (naphtha) via a special process before MX (mixed xylene) is extracted from naphtha and PX (para-xylene) is further extracted. PTA is made of PX (65%~67% contained) in the solvent of acetic acid, and coarse terephthalic acid is produced via oxidation in the air (35%~33% O2 contained) by the help of a catalyst. Finally the coarse terephthalic acid is hydrogenated for refinement, and the purified terephthalic acid (PTA final product) is obtained via purifying, crystallizing, separating and drying.
