REPLEN ABSORBENT
Type 3A
REPLEN ABSORBENT Type 3A, the potassium form of
the Type A crystal structure, is an alkali metal
alumino-silicate. Type 3A will absorb molecules
with critical diameters up to 3 angstroms.
Applications :
Type 3A is the preferred Molecular Sieve
absorbent for the commercial dehydration of
unsaturated hydrocarbon streams such as cracked
gas, propylene, butadiene and acetylene. It is
also used for drying polar liquids such as
ethanol.
The small pore size of Molecular Sieve Type 3A
prevents co-absorption of hydrocarbons by
excluding all other molecules while absorbing
water.
REPLEN ABSORBENT Type 4A
REPLEN ABSORBENT Type 4A, the sodium form of the
Type A crystal structure, is an alkali metal
alumino-silicate. Type 4A will absorb molecules
with critical diameters up to 4 angstroms.
Applications :
Type 4A is the preferred Molecular Sieve
absorbent for static dehydration in a closed gas
or liquid system. It is used as a static
desiccant in household refrigeration systems, in
packaging of drugs, electronic components, and
perishable chemicals, and as a water scavenger
in paint and plastic systems. Type 4A is also
used commercially in drying saturated
hydrocarbon streams.
All molecules which can be absorbed on Molecular
Sieve Type 3A can be adsorbed on Molecular Sieve
Type 4A.
REPLEN ABSORBENT Type 5A
REPLEN ABSORBENT Type 5A, the calcium form of
the Type A crystal structure, is an alkali metal
alumino-silicate. Type 5A will absorb molecules
with critical diameters up to 5 angstroms.
Applications :
Type 5A Molecular Sieve absorbent is used to
separate normal paraffin from branched
hydrocarbon and cyclic hydrocarbons through a
selective absorption process. Now it is largely
used in the separation of normal paraffin and is
paraffin. All molecules which can be absorbed on
Molecular Sieve Type 3A and 4A can be absorbed
on Molecular Sieve Type 5A.
REPLEN ABSORBENT Type 13X
REPLEN ABSORBENT Type 13X, the sodium form of
the Type X crystal structure, is an alkali metal
alumino-silicate. Type 13X will absorb molecules
with critical diameters up to 10 angstroms.
Applications :
Type 13X is used commercially for general gas
drying, air plant feed purification
(simultaneous removal of H2O and CO2) and liquid
hydrocarbon and natural gas sweetening (H2S and
mercaptan removal).
All molecules which can be absorbed on Molecular
Sieve Type 3A, 4A, and 5A can be adsorbed on
Type 13X. In addition, Type 13X can absorb
molecules of larger critical diameters, such as
aromatics and branched-chain hydrocarbons. |
