According to the annual report of China PX industrial chain 2017, the top ten PX (para-xylene) projects in China at the present stage are in the construction or preliminary work stage, and two major projects will be put into production in 2018, adding 8.5m t/a capacity.By 2020, China will have a total capacity of 34.96 million tons /a, and the demand for PX will be 28.5 million tons /a. China may transform from an importer of PX to an exporter, which will have a profound impact on the supply and demand pattern of PX in Asia and even the world.
The development of a complete set of autonomous aromatic hydrocarbon technologies and a large supply gap of PX have led to a new round of construction boom of aromatic hydrocarbon projects in China.However, as the technology and investment threshold drops, the scale of PX production capacity built in China in the next 10 years will be much larger than the net increase of demand in the same period, and the regional structural contradictions of production capacity will also be prominent.Several industry experts said that the aromatic chain must do a good market and investment planning.
Market demand is the decisive factor in the development of aromatic industry.PX consumption is mainly concentrated in the field of refined terephthalic acid (PTA). Currently, over 98% of PX is used in the production of PTA.PTA is an important raw material for polyester (PET) production, and over 98% of PTA is used for PET production.66% of PET is used to produce polyester fiber (polyester), and the rest is mainly used for PET bottle and diaphragm.The industry's consensus on PX USES is that 65% of PX is used for polyester, 31% for PET bottle tablets and 2% for PET film.
Driven by the sustainable development of domestic PTA, polyester and polyester industries, PX is in short supply at present.However, in recent years, China's polyester industry has been facing great pressure of structural adjustment.On the other hand, the domestic investment continues to increase, and the industry benefit deteriorates further.Some experts believe that cost and matching will be the core of future competition for PX production enterprises.
As an important source of PX raw materials, the future contradiction of PX industrial chain is not the structural allocation of PX resources, but the supply of PX raw materials.At present, there are plans to build and build all the reformer units in China, but there is still a big gap in the supply of reformer materials, no matter it is a 10m-grade alchemical integration project or a new PX production capacity.Therefore, when planning PX projects, enterprises should plan ahead on the supply of reorganized materials.
