The Application of 13X, 3A, 4A, and 5A Molecular Sieve

By admin Uncategorized 0 Comments

Molecular sieves are naturally occurring or synthetically made adsorbents known as zeolites. These are used extensively for the separation of fixed or permanent gases. The four main types of molecular sieves are 13X, 3A, 4A, and 5A. The type varies according to the molecule’s chemical formula, and each type comes with different pore size.

Let’s take a look at each of these molecular sieves individually.

13X Molecular Sieve

13X molecular sieves have a larger pore size as compared to any of the A-type sieves. The applications of 13X molecular sieves are as follows:

Used to dry and sweeten LPG and natural gas
Helps in removing moisture and carbon dioxide from the air for use in glass industries and steel refineries
Various usages in aerosol, glass, metal, and steel industries
Helps to preserve pharmaceutical materials and fruits
Helps in gas drying and purifying in NHS synthesis
Assists in the removal of oxidizers
Used in hydrogen purification systems
Used in the process of paraffin sweetening
Used to remove mercaptans from LPG
Used in refrigerant purifying and solvent drying

3A Molecular Sieve

3A molecular sieves have a pore size of 30 and are used extensively in drying alkyne polar liquids. The applications of 3A molecular sieves are as follows:

Used in the dehydration, separation, drying, and purification of ethanol in distilleries
Used in transformer oil dehydration system
Used for solvent drying in pharmaceutical plants
Used to dry pyrolysis gases in the process of ethylene manufacturing
Used to dry olefin and LPG
Helps in refrigerant drying and dehydration
Used in the dehydration of ethylene, cracked gas, natural gas propylene, methane, butadiene, and ethyne
Helps in drying cracking gases and liquids

4A Molecular Sieve

4A molecular sieve works on the principle of surface adsorption. The applications of 4A molecular sieves are as follows:

Used in the purification and generation of argon
Used in the regeneration and drying of transformer oil
Used to dry and purify ammonia gas and methane
Used in instrumental air drying
Used in the removal of carbon dioxide from the cracked gas
Used to dry liquefied natural gas and liquefied petroleum gas
Helps to purify gas for catalyst regeneration

5A Molecular Sieve

5A molecular sieves have higher crushing and adsorption ability. The applications of 5A molecular sieves are as follows:

Used in API packaging
Used in the packaging of pharmaceutical capsules and tablets
Used in the lining of bags for bulk containers
Helps in the safe loading, transportation, and storage of tablets and powders
Used as a laminate to foil
Used for food and pouches
