Molecular sieve is a moisture adsorbent having same-sized pores, which are less than 10 angstrom in diameter. This gives the moisture absorbent considerable surface area and thus increases its adsorption capacity. If we take a look at their composition, molecular sieves are also called zeolites.

1. Top 5 Applications of Molecular Sieves
Molecular sieve is a moisture adsorbent having same-sized pores, which are less than 10 angstrom in
diameter. This gives the moisture absorbent considerable surface area and thus increases its adsorption
capacity. If we take a look at their composition, molecular sieves are also called zeolites.
Molecular Sieve adsorbent is structured in such a manner that it adsorbs water and other polar
molecules. The uniformly-sized pores, remove all the moisture and pollutant particles, thus leaving
behind only the pure product.
Top 5 Applications of Molecular Sieves
1. Drying and Purification of Natural Gases and Liquids
2. Dehydration in Petroleum Industry
3. Drying Hydrogen Gas
4. Purification of Ethanol
5. Package Dehydration
1. Drying and Purification of Natural Gases and Liquids
One of the main uses of the Molecular Sieve adsorbent is in the natural gas and liquid industry, where it
is used to dehydrate and clean up gases like propane and butane. The zeolite is also used to remove
CO2, H2S, mercaptans and other particles from natural gases/liquids.
2. Dehydration in Petroleum Industry
Molecular Sieve adsorbent is employed in the petroleum industry for the drying of light-ends, like
olefins. The latter is used for cryogenic recovery. Molecular Sieve is also used to purify feed meant for
catalytic programs like isomerization, dimerization and alkylation.
3. Drying Hydrogen Gas
Many industries utilize molecular sieve for gas dehydration. The above mentioned processes are carried
out either through thermal swing or pressure swing adsorption.
4. Purification of Ethanol
Molecular Sieve adsorbent is widely used in ethanol production plants for large-scale removal of water.
It is also used for purification of food and pharmaceutical-grade ethanol.
5. Package Dehydration

2. Molecular Sieve adsorbent is placed inside packages meant to be transported long distance so that there
are no traces of humidity in the enclosed area. It also keeps away bad odors, mold and other micro-
organisms.
