thanks for reply.that I have done....can you please provide any specific website?

Mitul,

You have asked a very broad question. If all you're looking for is a definition, then the Wikipedia entry will do just fine.

If, however, you have a more specific question (e.g., you are looking for a supplier), then please provide more details.

Yes, what kind of molecules are you trying to sieve? If you have an application in mind, then please share that with us to help narrow down what you are trying to do. Such as trying to break the azeotrope in alcohol production, seperate different types of proteins in a pharmaceutical application, etc.

Thanks for reply....My application is specific to Gas dryers used in refinery.

I want more information like there manufacturing,composition,.....

A company like UOP www.uop.com will have plenty of information regarding mole sieve. We always call it magic dirt, but it is really some sort of aluminum/sillicon compound that preferentially will retain some molecules but for the most part let others pass through. They are used in gas processing, my experience is in air separation and syngas cold box preparation where they remove the small amounts of CO2 and H2O from the process stream so they don't make ice cubes in the cryogenic section. In this case, they are regenerated with high temp, low pressure gas to desorb the impurities.

Also used in pressure swing adsorbers for hydrogen plant syngas purification, in this case the sieve is regenerated by evacuating to low pressure and the low pressure gas is usually burned in the reformer.

Thanks
