About Molecular Sieves 3A:
3A molecular sieve refers to the type A sialic acid potassium salt. 3A molecular sieve can adsorb molecular whose critical diameter is no more than 3A.
It is commonly used for the drying of unsaturated hydrocarbon gas, such as ethylene, propylene, butadiene, etc.), and of polar liquid (such as ethanol, etc.). It is the first choice for deep drying, refining, and polymerization of gas and liquid in petroleum, chemical industry.
