MOLECULAR SIEVES BEADS 3A / 4A / 5A and 13X

MOLSIEVE – 3A / 4A / 5A is Molecular Sieve type 3A / 4A / 5A , an alumino Silicate having pore opening of about 4 Angstroms (0.4 micron) and typical chemical formula Na2O Al2 O 2SiO2 – nH2O

APPLICATIONS

Molsieve 3A / 4A / 5A Can be used to dehydrate most fluids both in static and dynamic Conditions

Static applications include usage in desiccant packages and for drying in insulating glass units Used for drying of refrigerant fluids used for drying of air Brakes.

Dynamic applications include drying and purification of Natural gas, LPG, air, inter gases and Solvents.

Even Molsieve 3A / 4A / 5A work under adverse operating Conditions like

Drying gases to very low dew points

Drying low relative humidity gases

Drying high temperature gases

Drying high velocity gases

Drying gas mixture etc.

Drying gases and removing other impurities simultaneously

Any combination of these conditions.

REGENERATION

MOLSIEVE 3A / 4A / 5A can be regenerated by evacuating or purging usually at elevated temperature.

The purge gas temperature must be sufficiently high to bring the molecular sieve to a level of 200 C to 300 C but not exceeding 600 Degree C.Higher temperature may cause physical degradation of molecular structure. The degree of regeneration depends on the temperature, pressure and composition of the purge gas and is a strong factor in affecting product purity. It is possible to dry fluids to less than 0:1 ppm total sulphur and CO2 if adequately regenerated.

MOLECULAR SIEVES 13 X

MOLSIEVE 13X is Molecular Sieve type 13X, an aluminoSilicate having pore opening of about 9 to 10 angstroms. Molsieve is manufactured from hydrated.aluminium silicate under strict temperature and pressure control to generate nuclei, a base of X-type Zeolite. The crystal cavities thus formed has affinity towards selective ions.

APPLICATIONS

Molsieve 13X can be used for removal of H2O and CO2 from gas and air streams.

Molsieve 13X can be used for removal of H2S and mercaptans from liquid and hydrocarbon fractions.

Molsieve 13X can be used for sweetening of natural gas containing H2S, mercaptans and thiophenes.

Molsieve 13X can be used for separation of heavy hydrocarbons from natural gas and air.

Molsieve 13X can be used for separation of N2 from O2.

Molsieve 13X can be used for catalyst bed protection.

Molsieve 13X can be used for removal of Water and solvent vapours from the inner space of insulating glass units.

Molsieve 13X can be used as an adsorbent in gas chromatography and in vacuum technique for non refrigerated adsorption traps.

REGENERATION

Molsieve 13X can be regenerated by evacuating or purging usually at elevated temperature. The purge gas temperature must be sufficiently high to bring the molecular sieve to a level of 200 C to 300 C but not exceeding 600 C.Higher temperature may cause physical degradation of molecular structure. The degree of regeneration depends on the temperature, pressure and composition of the purge gas and is a strong factor in affecting product purity. It is possible to dry fluids to less than 1 ppm total sulphur and CO2 if adequately regenerated.
