Questions about molecular sieves
Thread Content
I would like to ask the experts here: My company is planning to replace the molecular sieves, and Hangyang has recommended a manufacturer that produces X-HP-3 type molecular sieves, which are said to be able to extend their service life. Since our unit has not used it before, we are not aware of its actual performance. I would like to ask those who are more experienced – has anyone used this model of molecular sieve, and is its performance in practice good?
It is recommended to be more detailed, such as the gas composition, requirements for the purified gas at the outlet, and the current regeneration temperature
Ask Shanghai UOP about the price of the new 13X-APG molecular sieve Comparing with domestic ones. As for performance, it is approved by Hangyang, so generally there are no major issues.
Hello, I have some materials here. Could you please leave me an email address so you can take a look?

I think so too; since Hangyang recommends it, they must have used it in their projects already. It’s still a good idea to compare the prices with those of foreign molecular sieves. What is the exact price difference...... Is it small, or is it advisable to choose the foreign version? If the price difference is significant, choose the domestic one and give it a try after using it. If it is several sets of air separation units, it is recommended to use one domestic set and foreign sets for the others.
Also, if the operation is not done properly, even the best adsorbents are of no use~~
A good adsorbent can take a bit more abuse, while a poor one only needs to be used once. Every system requires careful maintenance and operation. In particular, the pre-cooling system and the molecular sieve system – these two systems are the most stable, but they also cause the most severe consequences when problems arise.
