Molecular sieves provide moisture
removal to extremely low levels with high adsorption capacity. Common
applications using molecular sieves include dehydration of moisture sensitive
formulations, Air dryers for plastics, air conditioning & refrigeration
systems, air brake systems, environmental pollution control, oxygen
concentrators, insulating glass, package dehydration & deodorization,
natural gas, petroleum & petrochemical drying & purification.
Moisture Absorption Solution |
Featuring innumerable empty
cavities, which is what endows it with the highest adsorption capacity in
comparison with other desiccants; these adsorbents are a synthetically
manufactured form of zeolite. However, one of the most expensive adsorbents
available today is this very quality.
Molecular sieve desiccant
provides a wide range of adsorption potential based on molecular size, sieve
crystal area and shape of the molecule. It is most popular wetness adsorbing
solution in industries because of excellent adsorption efficiency in comparison
to other moisture adsorption system.
There are many types of sizes
available like 3A, 4A, 5A and 13X molecular sieves based on
industrial requirement and adsorption capacity of moisture..Molecular sieves
are available with micropores in a number of sizes ranging in the nanometer
ranges. Typical micropore sizes range from 3 to 10 Angstroms contained in beads
measuring 1.5mm to 5mm.
This desiccant is based on
ingredients such as calcium alumina silicate. Most manufacturers provides
conventional prepackaged molecular sieves for industrial use. However, if you
need personalized alternatives, these can be acquired too. For this you would
need to solicit the services of a reputable desiccant manufacturer company.
Here are some other significant features of these desiccants.
• They can either be used
individually or custom blended with some other desiccants to give you an
optimal adsorption solution.
• Different desiccants have
different adsorption capacities. In the case of a molecular sieve, you can
expect it to adsorb moisture or gas up to 20 times its own weight.
• Since it is one of the
most aggressive desiccants available in the market today, it costs
significantly more than its other counterparts.
• Especially during the
transportation and warehousing stages of the distribution cycle, a number of
pharmaceutical companies make use of molecular sieve to protect packaged drugs
and antibiotics from humidity.
So, there are several industrial
applications in which this desiccant is commonly used, right from protecting
costly artwork to pre-purification of water to absorbing co2. It can also be
used with drug products, since this desiccant is odorless. Moreover, molecular
sieves are very appropriate for use in high temperature applications, with a
melting point that is slightly less than 2900 degrees Fahrenheit. They are also
used in chemical reactions since they are stable. However, one should always
wear a dust mask and gloves while handling it, as safe as this desiccant is.
