PX is mainly used for the production of purified terephthalic acid (PTA), PTA was used for further polyester fiber (polyester), non fiber polyester products such as polyester bottle and polyester film and other products.

As the core of the aromatic industry chain, there is a huge gap in our PX production. Academician of the Academy of Engineering Qian Xuhong said China, apparent consumption of 20 million 810 thousand tons in 2015 PX in China, which imports 11 million 650 thousand tons, an increase of 16.8% over 2014, 56% of foreign dependence. 1~6 months of this year, China imported 6 million 220 thousand tons of PX.

However, the NIMBY effect difficult to break deadlock in our country, PX is restricted by productivity construction. Economic and Technical Research Institute of Sinopec deputy director of consulting optimization center Luo Hongjing pointed out that the future Chinese will import large quantities of PX, is expected to 2020 Chinese is still 6 million tons more than the amount of imports.

China the slowing of neighboring countries is a substantial increase in production capacity. Data show that the global PX production capacity to maintain rapid growth, the capacity of 3/4 in asia. “These are the Chinese production target market.” Academician Qian Xuhong said. At present, Japan, South Korea, Singapore, China and Taiwan has become a major importer of PX in our country (region), accounting for 90% of total imports.
