Break through the neck!

On July 31, Sinochem held a successful commissioning ceremony at Tianchen Qixiang Nylon New Materials Co.
, Ltd.
in Zibo to celebrate the successful completion of the whole process of the first phase of the key equipment of the first domestic butadiene-based adiponitrile industrial production project, and the successful start-up and Produce premium products
.

As a high-end nylon variety, nylon 66 is a key raw material for the development of the high-end market of new materials in China.
It is widely used in daily life fields such as clothing, especially for the production of special tires, engines, etc.
, and is also an important material for lightweight automobiles
.

Nylon 66 has more superior performance than nylon 6
.
According to statistics, the product consumption ratio of nylon 66 to nylon 6 in developed industrialized countries such as Europe and the United States is about 1:1, while the ratio of nylon 66 to nylon 6 in China is only 1:10
.
As of the end of last year, the production capacity of nylon 6 in China was about 5 million tons, and the output was about 4 million tons.
The supply of nylon 66 was seriously insufficient.
The main reason was that the production technology of adiponitrile, the key raw material of nylon 66, has been monopolized by foreign countries for a long time.
, The products are supplied by the ration system, which limits the development of China's high-end polyamide industry
.
Just as bread is made without flour, nylon 66 is either useless or unusable
.

Therefore, the localization of adiponitrile has always been highly valued, and has been listed as a major scientific and technological research project by the state, and is clearly listed as an encouraged project in the "Industrial Structure Adjustment Guidance Catalog"
.

As a central enterprise, Sinochem fully recognizes the great significance of breaking through the "stuck neck" technology, and has carried out a large number of research experiments since 2011, and constantly summed up experience, developed a direct hydrocyanation method of butadiene with independent intellectual property rights Synthetic adiponitrile technology
.

In 2015, Sinochem's 50-ton/year adiponitrile pilot plant was successfully started up; in 2017, the 2,000-ton/year adiponitrile pilot plant was successfully started up, and all processes were successfully opened up, saving energy, material consumption and adiponitrile The development of complete sets of process technology has accumulated valuable experience, which has laid a good foundation for the construction of industrial demonstration units
.

On July 26, 2019, China Chemical announced that Tianchen Company will establish a joint venture Tianchen Qixiang with Qixiang Tengda and Zibo Tianxiang and other employee incentive platforms, and invest in the construction of a new nylon material project with an annual output of 1 million tons in Zibo Qilu Chemical Industrial Park, including The annual output of 300,000 tons of acrylonitrile co-production hydrocyanic acid plant, the annual output of 50,000 tons of sodium cyanide plant, the annual output of 90,000 tons of hydrocyanic acid plant, the annual output of 200,000 tons of adiponitrile plant, the annual output of 200,000 tons of plus Hydrogen plant, PA66 salt forming and slicing plant with an annual output of 200,000 tons
.

"There has always been a 'Chinese dream, an industrial dream' behind adiponitrile
.

Because the production technology has been monopolized by multinational companies for a long time, it has become one of the few key intermediates in China that has been 'stuck in the neck'", said Dai Hegen, secretary of the China Chemical Party Committee and chairman of the board.
Dreaming, China Chemical firmly shoulders the mission of the national team of self-reliance and self-improvement in science and technology, and fully deploys and promotes the technological research and development and investment and construction of adiponitrile
.
The successful start-up of the project also marks a solid step forward in China Chemical's journey to become a comprehensive solution service provider, high-end chemical and advanced material supplier in the field of industrial engineering
.
"

Under the circumstance of foreign technology blockade and almost zero reference materials, China Chemical China Tianchen Engineering Co.
, Ltd.
has finally overcome this "stuck neck" technology after 10 years of research and development
.

After inspecting nearly 20 chemical industry parks across the country, and analyzing their respective advantages and disadvantages from seven dimensions, including business environment, public works facilities, and local energy consumption and environmental protection indicators, Tianchen Company finally chose to build Tianchen Qixiang nylon new material in Zibo.

In June 2021, the Shandong Provincial Department of Industry and Information Technology issued the "Notice on Announcement of the List of Key Manufacturing Industry Chains and "Chain Master" Enterprises", Tianchen Qixiang has become a new material industry special nylon industry chain and high-end chemical industry Benzene-polyethylene Amide-nylon new material-textile and engineering materials industry chain double "chain master" enterprise
.

Focusing on adiponitrile and a series of new material projects, Tianchen Qixiang plans to build a "1+N" high-end new material industrial park with an area of ​​4,500 mu in Qilu Chemical Industrial Park, and together with upstream and downstream enterprises, create one main and two Deputy three industrial chains
.

"We have attracted 7 high-end nylon new material industry related companies, including Hangzhou Polyshun, Sinoma Technology, etc.
The total investment is expected to be 35 billion yuan, and the annual output value will reach 50 billion yuan
.
" Tianchen company party committee member and vice president Manager, Tianchen Qixiang Party Secretary and Chairman Liang Junxiang said that Tianchen Qixiang is focusing on existing and planned product and raw material demand to attract upstream and downstream production enterprises and extend the industrial chain
.
It is expected that in the next 10 years, the project will lead to the formation of a new material industry cluster with a total output value of 100 billion, and help Zibo to build a new industrialized strong city in the country
