Molecular Sieve Desiccant is available in
several bead sizes and types in fixed or bulk
quantities. Custom sized orders available.
A molecular sieve is a material containing
tiny pores of a precise and uniform size that
is used as an adsorbent for gases and liquids.
Molecular sieve adsorbents were developed to
remove water from liquids and gases more
efficiently than the older silica gel and
alumina desiccants. Molecular sieves, because
of their crystalline composition, will yield
virtually water-free products. This feature
makes molecular sieves particularly useful in
cryogenic operations where liquefaction of
gases is required and water must be eliminated
to avoid freezing.
Molecules small enough to pass through are
adsorbed while larger molecules are not. It is
different from a common filter in that it
operates on a molecular level. For instance, a
water molecule may be small enough to pass
through while larger molecules are not.
Because of this, they often function as a
desiccant. Molecular sieve can adsorb water up
to 24% of its own weight.
Molecular sieves offer adsorption selectivity
based on molecular size, molecular affinity
for the sieve crystal surface, and shape of
the molecule. Molecular sieve systems are
extremely simple to use for reducing
contaminants to nearly undetectable levels
compared to other technologies such as liquid
separation systems. This, along with the
higher efficiency compared to other adsorption
systems, has made molecular sieve systems a
popular engineering choice.
