Molecular Sieve 3A
Molecular Sieve 3A is a high performance potassium form of Type A zeolite with a pore size of approximately 3 Angstroms. Its crystalline aluminosilicate framework and spherical bead form provide excellent selective adsorption, strong mechanical stability, and long service life.
As one of the trusted molecular sieve suppliers in UAE and GCC, OozeChem offers high quality Molecular Sieve 3A for dehydration and purification applications. This sieve is specially designed for removing water from polar liquids such as ethanol, methanol, and other alcohols, while excluding larger molecules. It is ideal for drying unsaturated hydrocarbons like ethylene, propylene, and acetylene, as well as cracked gas, natural gas, and refrigerant gases. The precise 3 Angstrom pore size ensures selective water removal without co adsorption of larger organic molecules.
What is Molecular Sieve 3A?
Molecular Sieve 3A is a synthetic zeolite adsorbent engineered for efficient moisture removal from small polar molecules. Its unique pore size of 3 Angstroms allows only water molecules and very small gases to be adsorbed, preventing the uptake of hydrocarbons or larger organics.
It is commonly used in Pressure Swing Adsorption (PSA) and Thermal Swing Adsorption (TSA) systems for gas dehydration, solvent drying, and feed purification across chemical, petrochemical, and energy industries.
Key Features
- High selectivity for water adsorption with molecular size exclusion
- Ideal for small molecule dehydration such as water, ammonia, and hydrogen sulfide
- Excellent thermal and hydrothermal stability
- Regenerable through temperature or pressure swing operation
- Superior selectivity prevents adsorption of larger organic compounds
- Low attrition rate ensures long service life
Applications of Molecular Sieve 3A
- Dehydration of ethanol and other alcohols in distillation systems
- Drying of unsaturated hydrocarbons such as ethylene, propylene, butadiene, and acetylene
- Natural gas dehydration and sweetening
- Drying of cracked gas and refinery gas streams
- Refrigerant gas purification and drying
- Desiccant use in insulating glass units (IGU)
- Dehydration of polar solvents in chemical and pharmaceutical industries
- Drying of instrument and compressed air systems
- Suitable for both TSA and PSA systems
- Feed gas purification in petrochemical processes
- Hydrogen gas dehydration in fuel cell and hydrogen generation systems
- Pretreatment for liquefied natural gas (LNG) processing and mercury removal
- Water removal in ammonia synthesis gas for fertilizer and chemical manufacturing
OozeChem supplies Molecular Sieve 3A for industrial and commercial applications throughout the UAE, Saudi Arabia, Qatar, and other GCC countries, ensuring consistent performance and high purity results.

Regeneration Process
Molecular Sieve 3A can be regenerated by heating or through pressure swing desorption.
Typical regeneration temperatures range from 200°C to 300°C.
In PSA systems, a dry purge gas is used to remove adsorbed moisture effectively. The narrow pore structure ensures quick regeneration while maintaining high selectivity for water molecules.
Handling and Storage
- Store in original sealed packaging in a cool, dry, and well ventilated area
- Avoid exposure to liquid water or humid air before use
- Keep away from direct sunlight and heat sources
- Use in a well ventilated area during handling
When properly stored, OozeChem Molecular Sieve 3A retains full adsorption capacity for up to five years.
Safety Information
OozeChem Molecular Sieve 3A is non toxic, chemically stable, and safe for industrial use.
It should be handled in a well ventilated area to prevent dust inhalation.
Use protective gloves, goggles, and a dust mask during bulk handling or filling operations.
Avoid contact with liquid water, as premature moisture adsorption may reduce its effectiveness.
