On April 17, Sinopec’s first PTA project with an annual output of 3 million tons held a groundbreaking ceremony at Yizheng Chemical Fiber Company. The project adopts advanced energy-saving, environmentally friendly and short-process technology routes, and is planned to be completed and put into production in the first half of 2023. This is an important step for Sinopec to strengthen the aromatics industry chain, expand high-end new materials, and accelerate the construction of a “one base, two wings, and three new” industrial pattern.
PTA is the English abbreviation of purified terephthalic acid. As a derivative of petroleum, PTA connects the two major industries of petrochemicals and chemical fiber textiles, and is an important part of the aromatics industry chain. As one of the important bulk organic raw materials, PTA can be further processed into polyester fiber, film, plastic products, etc., and People’s basic necessities of life are closely related. In recent years, with the advancement of science and technology and application development, new material products extended by PTA have become increasingly widely used in the fields of life and health, energy conversion, aerospace, intelligent sensing and other fields.
The PTA project with an annual output of 3 million tons built by Sinopec in Yizheng Chemical Fiber has the advantages of large-scale single equipment, green and low carbon . On the one hand, it is conducive to the implementation of “vacating the cage for birds” of Yizheng Chemical Fiber’s existing two sets of PTA devices (with a total production capacity of 1 million tons), achieving green and low-carbon development, enhancing Yizheng Chemical Fiber’s polyester raw material supporting capabilities, and accelerating the advancement of subsequent smart fiber, New material projects such as biodegradable plastics; on the other hand, it will help Sinopec leverage its advantages in refining and chemical integration, strengthen and optimize the aromatics industry chain, accelerate the expansion of high-end new chemical materials, and meet consumers’ growing new needs for a better life. </p
