Application	- The strong ionic forces of the divalent calcium ion make it an excellent adsorbent to remove water, CO2, H2S from sour natural gas streams, while minimising COS formation. Light mercaptans are also adsorbed. - It is also used for the separation of normal and isoparaffins. - Production of high purity N2, O2, H2 and inert gases from mixed gas streams.

PRODUCTS DESCRIPTION

Product Description

Molecular Sieve 4A is made from zeolite powder 4A (>70%) and binder. Zeolite 4Ais generated by reaction of water, sodium hydroxide, sodium silicate and sodium aluminate. Molecular sieve 4A is usually used for in packaging of drugs, electronic components.Since 4A molecular sieve is more easier to be produced than 3A molecular sieve, 5A molecular sieve, 13X molecular sieve, it is more economic than other three Molecular Sieve Desiccant. Molecular Sieve 4A have the shape of beads, pallets.

More Details:

1. Synonym: Zeolite 4A, Molsive 4A, Zeolith 4A, 4A molecular sieve, 4 angstroms sieve

2. Typical Chemical Formula: Na2O.Al2O3.2SiO2.4,5H2O

3. CAS NO.: 1318-02-1

4. Silica-alumina ratio: SiO2/ Al2O3б≈2

Application:

1. Molecular sieve 4A can be used for drying and removing of CO2 from natural gas, LPG, air, etc.

2. Molecular sieve 4A can be used for removal of hydrocarbons, ammonia and methanol from gas streams (ammonia syn gas treating)

3. Molecular sieve 4A can be used in dehydration of refrigerant and air in the air break units of buses, trucks and locomotives

4. Molecular sieve 4A can be packed in small bags for packing desiccant for foods, electronics elements, drugs etc

Storage:
Keep 4A Molecular Sieve in an air tight container until ready for use to avoid unintended moisture adsorption.

Regeneration&Activation:

Molecular sieve 4A can be regenerated or activated either thermal regeneration method(Thermal Swing Adsorption, TSA); To remove moisture from a 4A molecular sieve, a temperature of 200-230°C (390-570°F)is required. Molecular sieve 4A 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.
