MOLECULAR SIEVE TYPE 4A

3A Molecular Sieve is a potassium form of aluminosilicate. The Molecular Sieve will adsorb molecules which have a
critical diameter less than three angstrom (He , H2 & CO).

Molecular Sieve 3A is cation exchanged potassium form of A type crystal structure. The potassium ion being larger than sodium ion is effectively exchanged in basic 4A type Molecular Sieve to reduce the pore size to 3 angstrom, and it enables selective adsorption depending upon molecular size.

Molecular Sieve 3A is used for dehydration of hydrocarbon streams in liquid phase or vapour phase due to high drying
efficiency, and minimizes the interface of hydrocarbon co-adsorption. Our Molecular Sieve, being spherical in
shape produces uniform packing and adsorbate diffusion in the adsorber, also exhibits high resistance to attrition and
physical damage during service.
