“Users and current status of “steric amine desulfurization and decarburization”
Thread Content
The industrial application of Nanhua Institute’s \"steric amine desulfurization and decarbonization technology\" has been going on for three to four years now. There isn’t very much comprehensive or detailed information available on its application; various limitations and constraints make it difficult to find further relevant materials. There are also very few reports on this topic in our HaiChuan platform, which is why I’m starting this thread to seek help, and I hope everyone can share their insights as well. “More than 20 manufacturers, including Yangzi Petrochemical, Golmud Refinery, and Mengjin Fertilizer Plant, have achieved goals such as increased production and reduced consumption by using steric amine series solvents, resulting in direct economic benefits of nearly 400 million yuan. ”What is available on the public internet are only fragmented pieces of information; it’s impossible to learn from them*. I hope friends can provide information on “project name, usage time, usage status, consumption statistics, energy-saving statistics, and statistics for new projects”. Thank you!

The research and development project on a series of solvents for the desulfurization and decarburization of sterically hindered amines, undertaken by the Nanjing Chemical Research Institute, has recently passed the evaluation of scientific and technological achievements organized by the Jiangsu Provincial Department of Science and Technology. The recycled low-pressure CO2 solvent and the sterically hindered amine desulfurization and decarbonization solvent developed under this project have already been put into industrial use. Experts recommend expanding their application areas further to accelerate their industrial adoption. This project developed a series of composite amine solvents for desulfurization and decarburization based on sterically hindered amines, and established a pilot-scale production facility for these solvents with an annual capacity of 500 tons. Compared with a methyl diethanolamine solution of the same concentration, the sulfide absorption capacity of the sterically hindered amine desulfurization solvent increased by over 100% ； When handling a gas flow rate increased by 40%, the total sulfur content in the purified gas was reduced by more than 50%. Compared with other amine-based decarburization solvents, the steric amine recovery low partial pressure CO2 solvent and the steric amine decarburization (MA) solvent offer advantages such as fast absorption speed, high capacity, high purification efficiency, and low energy consumption. Seven **patent applications** have been filed for this project, and 2 of them have been granted.
Regarding relevant papers, I can see an article by Jing Sanwei from Shanxi Fengxi Linyi right now; the rest are all materials that can be found on Baidu. If you have relevant materials, please send them to me via MS. Thank you :)
You can check out the journal \"Gas Purification\" on VIP, or on the Gas Purification website. I am currently involved in the development and promotion of this technology; feel free to reach out if you have any questions
Before May 2007, it can be said that the flue gas recovery system of Golmud’s 300,000-ton facility was not operating properly; the load reached only half of the designed level, and there was a lot of degradation product formation, resulting in frequent shutdowns. However: Several facilities in Inner Mongolia such as Sulihe and Chuanwei are operating well; it’s not clear what processing techniques are being used there.
