Molecular Sieves - An Introduction
Molecular Sieves are one of the most
commonly found desiccants. With their evenly-sized pores, they can absorb
moisture/impurity molecules, which are of the same size. Due to the even size,
larger molecules will not be absorbed while the same sized small molecules can
easily make their way through.
While Molecular Sieves have many different
uses, they are mainly utilized in the column chromatography process. Here the
Molecular Sieves act as a stationary phase, attracting the different components
of the mixture, which has to be separated. When the chromatography process
begins, the components having the highest molecular weight will leave the
Molecular Sieve bed first. This happens because the heavier molecules are
unable to pass through the molecular pores. It is only after the larger
molecules move that the smaller molecules will move forward. Molecular Sieves
also find use as desiccants.
Molecular Sieve 13X in Moisture
Controlling
There are various grades of Molecular
Sieves available in the market. These include Molecular Sieve 3A, 4A, 5A and
13X among others. While all these grades of Molecular Sieves are useful for different
purposes, Molecular Sieve 13X is mainly used for the effective control of
moisture in packaging, oil and gas and other sectors. The Molecular Sieve 13X
is known to have a pore size opening equal to that of the 10A grade. This makes
it handy in while removing moisture from liquid and gas refinements as it helps
in the effective absorption for bi-molecule and tri-molecules.
There are many other reasons as well why
Molecular Sieve 13X is used across industries. Molecular Sieve 13X can
effectively co-adsorb CO2 and H2O, H2O and H2S. Molecular Sieve 13X also
finds use as a desiccant for medical and compressor uses. This type of
desiccant is also used as a catalyze carrier in industries.
Other than effective moisture control, Molecular Sieve 13X is
also widely used in the air refining process by removing carbon dioxide and
water. It is employed in the Oxygen PSA (Pressure Swing Adsorption) process.
One can also effectively use Molecular Sieve 13X desiccant for the successful
removal of grease and solvents from different substances.This is one of the
most popular uses of Molecular Sieve 13X Other uses include removal of
mercaptans and hydrogen sulphide from natural gas using patented Zeochem
technology and effective removal of mercaptans and hydrogen sulphide from
hydrocarbon liquids.
All these uses prove the high efficiency of Molecular Sieve 13X in not
only moisture control but other areas as well
