1/2
Molecular Sieves GMGB 5A are crystalline alumino silicate
with SiO2, A1203 as 2:1. It is formed by an extensive cross-
linking of AlO4 and SiO4 tetrahedra, resulting in a uniform
pore
opening of 0.5 nm. GMGB manufactures 5A 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 specifications specified
in
the Bureau of Indian Standards: BIS 14211:1994. Specifically
it has very high water adsorption capacity, and mechanical
strength, and at the same time very low attrition loss. GMGB
uses clays from its own mines in the manufacture of this
product,
ensuring better control and uniformity in the quality ofthe
final
product.

--Packing:
Packing: Molecular Sieves GMGB SA are packed for industrial use
in airtight
MS drums under hot conditions with proper sealing arrangement so
that there is no
ingress of moisture during storage an transport. Standard
packing: 200/210 Lit.
drum size570x 860 (H) rom.
Life:
MOL.Sieves SA has infinite shelf life, when stores in packed
condition. The active
service life would depend, however, on the operating conditions
of the plant,
actual application, and the usage by the customer.

Loading:
MOL.Sieves SA does not require any special precution or
procedure during
loading. However, the health of the grid support is to be
checked, and the vessel
is to be cleaned of dust, foreign particles, etc. befor~ 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 drums
should be kept in the covered shed. In case of prolonged
exposure of the adsorbent
to moisture during storage / loading, it may require prolonged
regeneration at
higher temperature to restore its full adsorptive capacity.
Material Safety Data :
The product as such is neither inflammable, non toxic. Overall,
it is not hazardous.
Repeated exposure may irritate skin, eyes and respiratory
system. The product
gets hot as it is flfSt exposed to atmosphere due to adsorption
of moisture.
Regeneration:
-MOL Sieves SA should be regenerated thermally or by evacuation
with
simultaneous purge. For thermal regeneration, the adsorbent may
by heated to 200 -300 deg.C to remove water. The regeneration temp
depends on the type, conditionandcontent of the adsoroate.A

Applications :
1. Removel of traces of methanol and CO2 from N22 stream in
NitrogenWash Unit in Fetrilizer Plant.
2. Removal of H2O, CO2, H2Sand mercaptans from liquefied natural
gas.
3. Drying ofpurification of inert gas.
4. Oxygen airenrichment with concentration of 02 upto 93%
5. Purification andenrichmentofH2 from 60%to 98%and above.
