Molecular sieve Type 3A

,

Molecular Sieves GMGB 3A are crystalline alumino silicate

with SiO2, Al203 as 2:1. It is 'formed by an extensive cross-

linking of AIO4 and SiO4 tetrahedra, resulting in a uniformpore opening of 0.3 nm. GMGB manufactures 3A molecular

sieves in the form of extruded pellets and spheres by the State

of the Art technology in its plant at Mehsana (Gujarat-India).The products comfortably conform to the specificationsspecified in the Bureau of Indian Standards: BIS 14211:1994.Specifically it has very high water adsorption capacity, andmechanical strength, and at the same time very low attrition

loss. GMGB uses clays from its own mines in the manufac-

ture of this product, ensuring better control and uniformityin the quality of the final product.

Packing:Molecular Sieves GMGB 3Ajs packed for industrial use in airtight MS drumsunder hot conditions with proper sealing arrangement so that there is no ingressof moisture during storage and transport. Standard packing: 200/210 Lit. drumsize 570 x 860 (H) mm

Life:MOL.Sieves 3A has infinite shelf life, when stores in packed condition. The activeservice life would depend, however, on the operating conditions of the plant,actual application, and the usage by the customer.

Loading:MOL.Sieves 3A does not require any special precaution or procedure duringloading. However, the health of the grid support is to be checked, and the vesselis to be cleaned of dust, foreign particles, etc. before the adsorbent is loaded.During actual loading, the material should be poured carefully through funnel andchute so as to avoid dusting and attrition due to impact of free fall. The drumsshould be kept in the covered shed. In case of prolonged exposure of the adsorbentto moisture during storage / loading, it may require prolonged regeneration athigher temperature to restore its full adsorptive capacity.

Material Safety Data:The product as such is neither inflammable, nor toxic. Overall, it is not hazardous.Repeated exposure may irritate skin, eyes and respiratory system. The productgets hot as it is first exposed to atmosphere due to adsorption of moisture.

Regeneration:MOL Sieves 3A should be regenerated thermally or by evacuation withsimultaneous purge. For thermal regeneration, the adsorbent may by heated to 200- 270 deg.C to remove adsorbed water. The exact regeneration condition(temperature, purge gas flow, etc) depends on the application, and other operatingconditions. For better performance over prologed period GMGB MOL SIEVES3A should not be exposed to the temp. above 400 deg.C and hot gases containinghigh moisture should be avoided.

Applications:

1. Cracked Gas and Olefins drying2. Liquid or Gas Propylenedrying3. Drying of Organic Liquids like methanol, olefins, ethanol

(with denaturant methanol)4. Insulating Glass Manufacture5. Drying of CO2, solvents, reactant mixtures, gases & liquids in the

pharmaceuticals, paints, chemicals & allied industries.
