——Analysis of complex raw material million-ton ethylene complete technology
The million-ton ethylene complete technology that won the 2019 China Petroleum and Chemical Industry Federation Special Prize for Science and Technology Progress has strongly promoted the development of China's petrochemical industry, equipment manufacturing industry and related industries.
It can be called a new business card "created in China"
.
The petrochemical industry is the pillar industry of the national economy, and the ethylene plant is the leader of the petrochemical industry.
The ethylene, propylene, butadiene and by-product benzene, toluene and xylene are the most important basic organic chemical raw materials.
The downstream derived synthetic resin, Synthetic fibers, synthetic rubber and organic chemical products are widely used in all walks of life and play an important role in developing the economy, improving people's livelihood and safeguarding national defense
.
In 2019, China's ethylene production capacity was 28.
89 million tons/year, with a self-sufficiency rate of 56%.
It is expected that the ethylene production capacity will reach 42 million tons/year in 2025, with a self-sufficiency rate of 66.
7%.
The development of China's ethylene industry has a huge demand for advanced ethylene complete sets of technologies
.
In order to meet the needs of the development of the national economy, as early as 1983, when Sinopec Corporation was established, the development of ethylene technology was started
.
In order to develop a complete set of ethylene technologies, the project team has created 15 experimental devices/R&D platforms and 8 databases covering ethylene process research, catalyst research, major equipment development and key technology verification, and independently developed 20 models covering the entire ethylene process.
It has been industrially verified, which has laid a solid technical foundation for the development of complete sets of ethylene technologies
.
This complete set of technologies has innovatively developed a series of cracking furnace technologies suitable for super-large long-cycle and high-efficiency of complex raw materials, and has overcome the problem that high selectivity and long operation cycle cannot be taken into account.
The world's largest single-furnace capacity of 300,000 tons/year cracking furnace has been completed and ready to be put into production; at the same time, it has pioneered a new high-efficiency separation process with low energy consumption and high ethylene recovery rate with fractional condensation fractionation tower and distribution separation as the core, which significantly improves the product recovery rate.
Effectively reduce energy consumption; created a full range of high-performance catalysts covering the whole process of ethylene with high selective hydrogenation of carbon 2 and carbon 3 and methanation at low temperature and high space velocity.
It has developed a series of special green and high-efficiency technologies, and has exported related technical achievements
.
The complete set of technologies has also achieved fruitful intellectual property achievements, with a total of 206 authorized patents, 157 invention patents (64 foreign patents), 137 papers, 4 monographs, and 15 standards, forming a complete technical system for the follow-up.
The rapid development of related technologies has laid a solid foundation
.
The complete set of technology for ethylene with complex raw materials of millions of tons has been widely promoted and applied
.
In 2018, the complete set of ethylene technology of complex raw material million-ton level passed the appraisal of China Petroleum and Chemical Industry Federation, and won the special prize of scientific and technological progress of China Petroleum and Chemical Industry Federation in 2019
.
The research and development and industrial application of this complete set of technologies have led the technological progress of China's ethylene industry, supported the rapid development of the ethylene industry, and strongly promoted the development of China's petrochemical industry, equipment manufacturing industry and related industries, and produced huge economic and social benefits.
It is a milestone meaning
