- PTA(pure terephthalic Acid) is usually produced by two successive processes of p-xylene liquid phase oxidation and hydrogenation purification. EPTA(known as Eastman PTA) is produced by the oxidation with lower temperature and digestion processes. PTA是近年来国内大型装置投资的热点之一,我国已引进了各种PTA生产工艺,其中近年来引进的以低温氧化和无加氢精制工序的EPTA生产工艺有其独特之处,与高温氧化和加氢精制工艺有明显不同。
