If you look carefully at the washing instructions on the clothes, you will find that the fabric items are usually labeled “cotton”, “polyester”, “polyester” and so on, the latter two, it is the downstream of the PX products. In fact, we are surrounded by telephone, cell phone cases, mineral water bottles, computer shells, capsules, curtains, cameras, etc., none of the materials with PX associated with China has become the world's largest producer and consumer of PX, production capacity of about 20% of the world's consumption of about 32% of the world. It is expected that in the next few years, China's PX still need to import large quantities. So the PX project, in the end, still need to continue to develop? 

The scientific name of PX is “1,4-xylene”, also known as “paraxylene”, is a colorless and transparent liquid derived from petroleum, but also an important bulk chemical base material. In the modern petrochemical system, the aromatics industry represented by PX and the olefin industry represented by ethylene are known as the “two big families” of petrochemicals. In the economic field, PX downstream industry chain is long and high value-added, therefore, PX production and processing is also known as the “golden industry chain”. 

“PX project generally refers to the construction of PX purification plant, the process of fractionation of petroleum produced toluene, mixed xylene and other substances for disproportionation, isomerization, separation, and then purification of PX. PX in the industry chain is key, not only to support the textile industry to save the land for cotton planting, but also indirectly through the enhancement of gasoline octane number to improve air quality.

Although China's PX production capacity ranks first in the world, there is a large demand gap due to the mismatch of the surge in downstream PTA production capacity and under-exploited export potential.

The PX industry has high capital and technical requirements, but the associated industries absorb many jobs, and its development is crucial to the economy and employment, requiring stronger regulation and emergency management.
