The first set of third-generation domestic aromatic hydrocarbon technology was completed and put into operation

On June 8, according to the news office of Sinopec, the first set of industrial application equipment of Sinopec's third-generation aromatic hydrocarbon technology, Jiujiang Petrochemical's 890,000 tons/year aromatic hydrocarbon joint unit, was successfully started up and produced qualified products
.
The project is a key project of the national industrial layout, and the successful start-up marks that China's aromatics complete sets of technologies have reached the international leading level, significantly improving the technical level and international competitiveness of China's aromatics production, and will lay the foundation
for the local industrial cluster of more than 100 billion yuan.

The device adopts the third-generation aromatic hydrocarbon technology with independent intellectual property rights of Sinopec, which has the advantages
of low investment cost, low energy consumption and high efficiency of catalyst application.
This technology is the first to develop and apply a complete set of single-tower adsorption and separation technology, which will change the past double-tower adsorption into single-tower adsorption, increase the utilization rate of adsorbent by 10%, reduce investment costs by nearly 20%, and operate more stable
.
At the same time, through the comprehensive optimization and utilization of energy integration and utilization of the whole process of the aromatic hydrocarbon joint unit, the integrated heat combination and the efficient utilization of low temperature heat, the energy consumption of the device is less than 220 kg of standard oil / ton PX, which is 30% less energy consumption than similar aromatic hydrocarbon devices, reaching the international leading level
.

The complete set of aromatic hydrocarbon technology takes the production of paraxylene as the core and is a landmark technology
representing the level of petrochemical development in a country.
The first and second generation of high-efficiency and environmentally friendly aromatic hydrocarbon complete sets of technical application units were successfully put into operation
in 2013 and 2019 in Sinopec Hainan Refinery.
In order to further consolidate the leading edge of aromatics technology, Sinopec's aromatics technology research and development team has been working non-stop, and in just two years, it has successively developed a series of new technologies such as single-tower aromatic hydrocarbon adsorption separation process and digital control of aromatic hydrocarbon devices, forming a third-generation aromatic hydrocarbon complete set of technologies
with international leading level.

Aromatic hydrocarbon products are widely used in chemical fiber, light industry, electronics, construction and other aspects of the national economy, most of them will become raw materials for polyester fiber, processed into clothing, not only to solve the problem of raw materials for clothing, but also to solve the contradiction of grain and cotton land competition, is an indispensable basic chemical product
for people's lives.
As the first large-scale aromatics project in central China, Jiujiang Petrochemical Aromatics Project will play an important role
in promoting the rise of China's central region and leveraging the development of the integrated industrial chain of refining and chemical industry.
The successful start-up and production of qualified products began construction on May 9, 2020, with the goal of creating a benchmark, achieving high standards for CCCC on January 20, 2022, and producing qualified products
today.

Sinopec resolutely assumes the role of national strategic scientific and technological force
.
In December 2013, the Hainan refining and chemical aromatics joint unit built using the self-developed high-efficiency and environmentally friendly aromatics complete set of technologies was successfully put into operation, making China the third country to master the technology after the United States and France, and the project of "Efficient and environmentally friendly aromatics complete sets of technology development and application" won the 2015 National Science and Technology Progress Special Award
。 After years of development, Sinopec has formed a more perfect petrochemical main technology, aromatics, organic raw materials, coal chemical and synthetic materials and other key core technologies have made new breakthroughs, for example, hydrogen peroxide system of propylene oxide (HPPO) industrial demonstration device successfully operated, making China the third country in the world to master HPPO technology; The world's largest 3.
6 million tons/year coal-to-olefin plant was successfully put into operation, becoming the first supplier to master the whole process of MTO reaction and separation technology; It has broken through the industrial technology of 48K carbon fiber large tow and realized the large-scale application
of carbon fiber continuous sucker rod in the oilfield field for the first time in the world.
