Type 3A
Composition 0.6 K2O: 0.40 Na2O : 1 Al2O3 : 2.0 ± 0.1SiO2 : x H2O
Description The 3A form is made by substituting potassium cations for the inherent sodium ions of the 4A structure, reducing the effective pore size to ~3A, excluding diameter >3A, e.g., ethane.
PRODUCTS DESCRIPTION
Major Applications Commercial dehydration of unsaturated hydrocarbon streams, including cracked gas, propylene, butadiene, acetylene; drying polar liquids such as methanol and ethanol. Adsorption of molecules such as NH3 and H2O from a N2/H2 flow. Considered a general-purpose drying agent in polar and nonpolar media.

Application
1) Drying of unsaturated hydrocarbons(e.g.. ethylene,propylene,butadien)
2)Cracked Gas Drying
3) Drying of natural gas,if COS minimization is essential, or a minimum co-adsorption of hydrocarbons is required.
4) Drying of highly polar compounds,such as methanol and ethanol
5) Drying of liquid alcohol
6) Static,(non-regenerative) dehydration of insulating glass units,whether air filled or gas-filled.
