摘要
对二甲苯(Paraxylene,PX)是一种重要的基础有机化工原料,但PX分离技术曾一度成为我国芳烃成套技术的短板。本文概述了PX分离技术的现状并介绍了我国PX分离技术的最新进展,提出了PX分离工艺的发展方向。
Paraxylene(PX)is an important basic organic chemical raw material,but PX separation technology once become the short board of our aromatic hydrocarbon technology.This paper provided an overview of the state of PX separation technology and introduced the latest progress of PX separation technology in our country.The development direction of PX separation process was proposed in the end.
