Who is the best in membrane separation at the moment? (Reprinted)
Thread Content
It is said that membrane separation is an emerging industry in China, with several companies such as Xiamen Sanda Membranes, Hangzhou Zhongda Membranes, Nanjing Kemi Technology, and Chengdu Saipuixing Technology operating in this field. Among them, Xiamen Sanda Membranes seems to hold a significant market share in the pharmaceutical industry. The Dalian Institute of Physics and Chemistry is very strong in universities; it is likely to be a leader in this field. How much do people know about this information? Feel free to discuss!
Our inorganic membranes (ceramic membranes) at Nanjing Tech University are the best in the country! ! ! Haha, this isn’t advertising; it’s true! ! !
Hehe, supporting the person above.:lol
Our unit uses the one from Dalian Institute of Physics and Chemistry, and the results are good.
The inorganic membrane technology level at the Dalian Institute of Chemical Physics is very high.
The molecular sieve membranes developed by the Dalian Institute of Chemical Physics have been put into industrial use. It is mainly used for the dehydration of organic solvents, especially fuel ethanol.
I’m wondering what the corrosion resistance of your company’s ceramic membranes is in a 32% hydrochloric acid environment? We’ve used products from other companies, but the results have not been satisfactory. Last edited by chc1125 on 2009-3-16 at 15:25.]
What ones are there abroad? ? ?
Who’s the best?? What do you want to achieve, OP? You should know that membrane technology can be divided into 10 categories and 100 subcategories
He is probably the best expert in membrane separation for liquid materials; he is the chief engineer at Sunda. I’ve heard of few companies that have achieved anything notable in this area. This is his blog: http://blog.sina.com.cn/xmhsq1960
Now, wastewater treatment design companies in Hangzhou are starting to use membranes, though most of these membranes are of American origin. I wonder if any domestic companies have tried to establish contact with them
Chengdu Saipuixing Technology has previously used membrane separation to produce CO, with good operational results; however, the overall output of CO was not high. As for other applications such as membrane separation for hydrogen production, these are technologies and systems that have been developed over many years, and basically any company involved in membrane separation technology can engage in such activities. It’s just that for the core components… the degree of localization of membranes has not been high; high-quality membranes still need to be imported from abroad. For example, the ion membranes used in chlor-alkali industry for producing caustic soda rely on imports.
Saipuixing has extensive experience in membrane separation systems for hydrogen recovery from the off-gases generated in ammonia and methanol production, with around twenty to thirty such systems in operation. This post was last edited by riia on 2008-4-26 00:53]
When it comes to membrane separation for the recovery of hydrogen from exhaust gases, Chengdu Saipuixing remains the leader
The Dalian Institute of Chemical Physics is really good
Actually, the original poster should refine this topic and specify which type of membrane it is for. For example, the gas film commonly used in the chemical industry. Do you mean manufacturers or engineering contractors when you say the best? This post was last edited by chc1125 on 2009-3-16 15:27.]
Dalian Ouke is said to be pretty good too, hehe!
Generally speaking, the performance of domestic membranes is somewhat inferior to that of imported membranes; imported membranes account for a significant proportion in existing production facilities, and domestic membranes still need to improve
