PTA生产工艺进展及工艺技术比较

近年来全球对PTA的需求增长推动了PTA生产技术的不断发展，寻求更经济的生产工艺或高纯度对苯二甲酸制造技术已经成为研究的主要方向。文章综合介绍了目前国内外各类PTA的生产工艺及其技术发展状况，并对其中两种主要生产工艺就技术、产品质量、成本、投资费用及其发展前景进行了横向比较分析，展望了PTA新技术的发展方向。

Advance of PTA Producing Technologies and Comparison of Different Processes

In recent years, the rapid increase of global PTA demand has propelled the continues development of PTA producing technology, therefore, it has become the main direction of research to seek more economic process or producing process of high purity TA. Based on review of the various PTA producing processes at home and abroad and their development situation, this paper made some lateral comparison and analysis on the technology, products quality, cost, investment cost and developing trend of two main processes, and prospected the developing direction of PTA new technology.
