Different Size 3A Molecular Sieve Desiccant For Drying Natural Gas
3A Molecular Sieve Desiccant Description
Molecular Sieve 3A is an alkali metal alumino-silicate; it is the potassium form of the type A crystal structure. Type 3A has an effective pore opening of about 3 angstroms (0.3nm). This is large enough to allow in moisture, but excludes molecules such as unsaturated hydrocarbons which can potentially form polymers; and this maximizes lifetime when dehydrating such molecules
