On July 10, the 300,000-ton/year styrene complete technology industrial application project completed by Changzhou Ruihua Chemical Engineering Technology Co.
, Ltd.
passed the scientific and technological achievement evaluation organized by the China Private Science and Technology Promotion Association in Beijing
.
The experts at the meeting agreed that the complete set of technology has independent intellectual property rights, the technical level is domestically leading, and the economic and social benefits are significant
.
The expert group believes that this technology has innovatively developed low energy consumption liquid phase alkylation ethylbenzene synthesis and high vacuum, low water ratio ethylbenzene adiabatic dehydrogenation reaction process, and designed a unique ethylbenzene dehydrogenation high temperature system treatment plan and dehydrogenation Key equipment such as the reactor, ethylbenzene superheater and intermediate heat exchanger extend the operation cycle of the equipment; the material consumption is 1.
0555 tons (benzene + ethylene)/ton styrene, and the energy consumption is 208.
9 kg standard oil/ton styrene, which is in line with the national standard Compared with the advanced index of, the energy consumption is reduced by 21%.
According to the inspection by the City Product Quality Supervision and Inspection Institute, the purity of styrene reaches 99.
9%, which is better than the 99.
8% index of the national standard superior grade
.
At present, the technology has been successfully applied in Xinyang Technology Group Co.
, Ltd.
and so on
.
Experts suggest that the promotion of this complete set of technologies should be further increased to meet market demand
.
? According to Xu Zhigang, Chairman of Ruihua Company, the company independently developed a complete set of 300,000 tons/year styrene technology and built the first domestic device with independent intellectual property rights.
It was successfully started in May 2016
.
Up to now, the device has achieved long-term and stable operation for more than three consecutive years, and has excellent performance indicators.
It has become the device with the largest scale of domestic styrene technology construction and application and the best operating performance
.
? Xu Zhigang said that most of the styrene plants in operation in China are domestically produced technical plants with an annual output of 250,000 tons, and the average international production capacity is 260,000 tons/year
.
Previously, China's styrene plants with an annual output of 300,000 tons/year and above were all constructed with foreign styrene technology, and foreign technology was in a monopoly position
.
The successful application of Ruihua's 300,000 tons/year styrene package technology broke the foreign monopoly and laid the foundation for the development of China's super large-scale styrene project
.
? "Some styrene plants built by domestic technology still have problems such as high energy and material consumption and poor economic benefits.
.
The total energy consumption of domestic styrene plants is generally about 280 kg of standard oil/ton of styrene, and the total material consumption is generally 1.
075 tons (benzene + ethylene)/ton of styrene
.
It is estimated that Ruihua's 300,000 tons/year styrene package technology can greatly reduce energy consumption and material consumption, and can save about 80 million yuan in cost each year
.
"Xu Zhigang said
.
Although China's styrene production capacity has developed rapidly in recent years, the downstream products have developed more rapidly and the market gap has been larger
.
In the past 10 years, the import volume of styrene monomer has remained at a scale of 3.
5 million tons per year.
Domestic styrene products still cannot meet market demand
.
"In order to alleviate the shortage of styrene resources in China, after the success of the 300,000 tons/year styrene package technology, we have signed contracts and gradually implemented 400,000 tons/year and 500,000 tons/year.
Tonnage/year, 600,000 tons/year styrene complete technology project, and 800,000 tons/year styrene complete technology project will soon be launched to create a world-class super large-scale styrene complete technology project
.
Especially in Southeast Asia, where styrene resources are in short supply, there are broad prospects for the promotion of complete sets of styrene technology abroad
.
"Xu Zhigang told reporters
