MOLECULAR SIEVE TYPE 3A
3A Molecular Sieve is a potassium form of aluminosilicate.The Molecular Seive 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 .
