3A molecular sieve is most commonly used for dehydration and can be applied in both pressure swing adsorption (PSA) and vacuum swing adsorption (VSA) systems units to remove H2O.  3A has a quick mass transfer rate, high mechanical strength, low attrition, and can minimize byproduct formation. This molecular sieve can be used to dehydrate unsaturated hydrocarbon streams, while offering low levels of hydrocarbon co-adsorption, which makes it a suitable product for natural gas plants looking to minimize hydrocarbon loss or reduce sulfur peaks. 3A is a versatile molecular sieve that has a wide range of applications including those in natural and petroleum gas dehydration, refrigerant drying, and for use in insulated glass.
