Different Size 3A Molecular Sieve Desiccant Drying Natural Gas

More Details:

Synonym: Zeolite 3A, Molsive 3A, Zeolith 3A

Typical Chemical Formula: 0,45 K2O . 0,55 Na2O . Al2O3 . 2 SiO2 . n H2O

CAS NO.:  1318-02-1

Silica-alumina ratio: SiO2/ Al2O3≈2

Application:

1. Zeolite molecular sieve 3A is used for drying of unsaturated hydrocarbons (e.g. ethylene, propylene, butadiene)

2. Zeolite molecular sieve 3A is used in deep desiccation of cracked petroleum gases, such as ethylene, propylene, butadiene, acetylene and natural gas, and of polar liquid, such as ethanol, LPG and solvent

3. Zeolite molecular sieve 3A is used in drying of natural gas, if COS minimization is essential, or a minimum co-adsorption of hydrocarbons is required

4. Zeolite molecular sieve 3A is used in drying of highly polar compounds, such as methanol and ethanol

5. Zeolite molecular sieve 3A is used in drying of refrigerants (e.g. XH-5, XH-7 etc)

6. Zeolite molecular sieve 3A is used in dehydration of benzene, toluene, xylene and other solvents 

7. Zeolite molecular sieve 3A is used in static, (non-regenerative) dehydration of insulating glass units

Storage:

Keep 3A molecular sieve in an air tight container until ready for use to avoid unintended moisture adsorption.

Regeneration&Activation:

Molecular sieve 3A can be regenerated or activated either thermal regeneration method(Thermal Swing Adsorption, TSA); To remove moisture from a 3A molecular sieve, a temperature of 200-230°C (390-570°F)is required. Molecular sieve 3A can also be regnerated or activated by lowering the pressure in the case of pressure swing processes (PSA). A properly regenerated or activated molecular sieve can give moisture dew points below -100°C. The outlet concentrations on a pressure swing process will depend on the gas present, and on the conditions of the process.
