How to remove the atomized water in gas
Thread Content
There is a significant amount of atomized water in the gas; what methods can be used to remove it effectively? Thank you.
I’m not sure what the requirements are regarding moisture content in your products. If a small amount of water is acceptable, I believe that using two precision filters with a capacity of 1 micron and 0.1 micron each will be sufficient to remove most of the moisture. If higher standards are required, adsorbents based on molecular sieves would be more effective. A cryogenic machine can also be used to condense the gas and remove some of the moisture.
What is the pressure resistance of precision filters? If it’s too high, it will affect the air flow rate. Additionally, what is the quality of the filter elements? What material should be used to ensure water resistance?
From our experience, in situations with high water content, a 1-micron precision filter encounters significant resistance when used alone. Our filter elements are made of fiberglass, with a metal frame inside; however, the backup air we use contains not only water but also oil and other impurities. As a result, the lifespan of these filters is short, and we have observed instances where the metal frame corrodes and falls off, leading to unsatisfactory filtering performance. This might not be exactly the same as the original poster’s situation; it’s just for reference. In my opinion, this filter element is a consumable; it is suitable for performing the initial stages of filtration in situations where the quality of the air supply is poor, but its final filtering effect is not very good. Glass fiber is waterproof, and the internal framework should preferably be made of stainless steel.
