Type 4A

Molecular Sieve Type 4A is the sodium form of Zeolite. Type 4A is typically used in regenerable drying systems to remove water vapor or contaminants which have a smaller critical diameter than 4 angstroms. With a smaller pore size, Type 4A is less subject to contamination; however, the moisture absorption rate will be less than that of Type 13X.

Molecular Sieve

Type 13X

Molecular Sieve Type 13X is a modified form of the sodium Zeolite with a pore diameter of 10 angstroms. Type 13X is used commercially for general gas drying, air plant feed purification (simultaneous removal of Hp and CO2) and liquid hydrocarbon and natural gas sweetening (H2S and mercaptan removal). The larger pore size allows for faster absorption of moisture; however, it is more subject to contamination.

Molecular Sieve

Activated Alumina

Activated Alumina is synthetically produced amorphous oxides from aluminum trihydrate. The end product is a beaded material with high absorbtion capabilities. It is used as a Claus Catalyst in natural gas and refining and can reduce the dewpoint of the air to -40C. Activated Alumina can remove a variety of contaminants from styrene, polyethylene, ethylene, light hydrocarbons and air. Aluminas are very nonreactive absorbents giving off low heat.
