From fertilizer bags to clothes to the world's largest producer of chemical fiber

However, an important difficulty in the production of aromatics, adsorbents, has not been successfully developed. Without qualified adsorbents, it is impossible to obtain high purity aromatic product paraxylene.

After several failures, in 2008, the second generation of adsorbents was successfully developed, and only the most critical bastion of aromatic technology - the adsorption separation device was not overcome. Because of the comprehensive blockade of foreign technology, in the early stage of the project, everything had to be started from scratch, and experts and scholars who had conducted research and development work for decades felt helpless, which almost became an impossible task.

Under the pressure of all parties, Sun Lily, general manager of Sinopec Engineering Construction Co., LTD., began to lead everyone to analyze from the principle and function, focusing on the most critical technical difficulties, the layer by layer grid that supports the adsorbent in the adsorption separation device.

On December 15, 2013, Hainan Refining and aromatics joint plant produced first-level paraxylene products, and Sinopec became the third company in the world with a complete set of patented technology for aromatics production.

Sinopec's "Development and Application of High Efficiency and Environmental Protection Aromatic hydrocarbon Complete Set Technology" won the 2015 National Science and Technology Progress Grand Prize.

Sinopec has been grinding a sword for 40 years! With this sword, we will cut off the monopoly and profiteering of certain countries!

Although, in the tide of world economic integration, China's reform and opening up, the introduction of foreign advanced technology to enhance China's innovation and manufacturing capacity; However, the most core and most related to the lifeblood of the national economy are all made by ourselves! Now, even if we want to import, we can get a preferential price!

Innovation is the right to speak! Innovation is pricing power! The complete set of technologies supported by the complete innovation is the base of the chemical power!

From "Dacron" to ylon, from aromatic complete sets of technology to polyester industry chain, from letting people wear shirts to wear good clothes, China's petrochemical industry workers silently overcome one technical difficulty after another!

Now, China has become the world's first chemical fiber production and consumption country. From the problem of people's clothing, it can be seen that for a large country, the living standard of its people is closely related to the degree of industrialization. It is because of the development of the chemical industry that "difficult to dress" has become a thing of the past in China. In just a few decades, more than one billion Chinese people can wear warm and decent clothes!

Development of chemical fiber

With the rapid progress of polyester industry technology, the performance of chemical fiber has far exceeded that of natural fibers (cotton, hemp, etc.). It can be said that the current chemical fiber, second kill all natural fibers, including the so-called "soft gold" cashmere.

Because it can be customized: you want down, make down; You want cashmere, you make cashmere, and the feel, the physical properties are better than the best cashmere.

Differentiated polyester fibers, clothing designers can think of, can not think of, want all the performance, has been available. Now the most advanced fabrics, are chemical fiber, rather than cotton, wool and the like.
