Our tower separation technology is among the most advanced in the world

After 10 years of research, Professor Zhang Zhibing of the Nanjing University Separation Engineering Research Center researched and developed a tower separation technology with outstanding energy-saving and emission-reduction effects. On April 11, this technology passed the appraisal organized by the China Petroleum and Chemical Industry Association in Nanjing. . An expert group consisting of academicians of the Chinese Academy of Engineering, Ouyang Pingkai, Chen Bingzhen, and Zhang Quanxing, believes that the new tower separation technology has reached an internationally advanced level in general. Diamond-shaped mother-float float valves and other technologies are internationally pioneered.
Up to now, the results of this project have been applied in dozens of domestic enterprises, with an accumulated recovery of 670,000 tons of organic solvents, reduction of nitrogen oxides by 404,000 tons, and resource-based production of 50% of nitric acid by 1.125 million tons, saving at least 20,000 tons of standards. The steam generated by coal accounts for a cumulative increase of 13 billion yuan in production value. The project has won 12 national invention patents.
The Separation Engineering Research Center of Nanjing University takes the separation of chemical mixtures in the development process industry as its mission. It took 10 years to achieve a breakthrough in the research and application of new separation technologies for energy-saving and emission reduction towers. Based on the non-equilibrium thermodynamic entropy increase rate function, the researcher directly correlates the entropy increase rate of the plate with its specific structural parameters, and proposes an energy-saving new structural plate design method. This new method is the first in the history of plate research at home and abroad. Engineering tests have shown that compared with the traditional guided trapezoidal valve trays, the super-valve trays developed based on this new method have a pressure drop of only 42% that of conventional trays and an average 36% increase in the efficiency of liquid plates. The flexibility of operation is 1.67 times that of conventional trays, and its use in industry can significantly increase separation efficiency and reduce energy consumption.
On this basis, the research group has also developed a new process equipment for nitrogen oxide exhaust gas treatment and a new high-tech recovery equipment for organic solvent dimethylacetamide in the spinning process. The results of industrial application of these two equipment indicate that more than 99% of the nitrogen oxides active components in industrial waste gas can be captured and recycled into nitric acid, and the nitrogen oxide content in the exhaust gas is much lower than the national standard requirement of 50 mg/m3; The dimethylacetamide completely satisfies the production of high-quality spandex polymer fibers with a recovery rate of more than 99.5%. The purity of the product and the content of water, alkali and acid are the best in the same international technology.
At present, China is facing a severe energy conservation and emission reduction situation. The high-precision separation of chemical substances in process industries, the effective use of fossil fuels and raw materials, and the recycling of chemical substances in the “three wastes” are all urgently needed for efficient separation technologies.
