Product Description

Product Description

 

5A Molecular Sieve
Molecular Sieve type 5A is an alkali alumino silicate; it is the calcium form of the Type A crystalstructure. Type 5A has an effective pore opening of about 5 angstroms (0.5nm). It will adsorbmolecules with a kinetic diameter of less than 5 Angstrom and exclude those larger.It is especially suitable for PSA adsorber applications where it may be used for the separation ofnormal-and iso-paraffins (C4 to C6 species), in PSA hydrogen purification and in oxygenconcentrators.

Applications

Typical Application

1)The strong ionic forces of the divalent alcium ion makes it an excellent asdorbent to remove water,CO2,H2S from sour natural gas streams, while minimising COS formation.
2)Light mercaptans are also adsorbed.
3)It is also used for the separation ofnormal-and iso paraffins.
4)Production of high purity N2,H2 and inert gases from mixed gas streams.


Regeneration
Molecular sieve Type 5A can be regenerated by either heating in the case of thermal swing processes; or by lowering the pressure in the case ofpressure swing processes.
To remove moisture from a 5A molecular sieve, a temperature of 250-300°C is required. A properly regenerated molecular sieve can give
moisture dew points below-100°C,or mercaptan or CO2 levels below 2 ppmv.
The outlet concentrations on a pressure swing process will depend on the gas present, and on the conditions of the proces.

Size:
5A-Zeolites are available in beads of 1-2 mm, (10x18mesh) 2-3 mm,(8xl2 mesh),
2.5-5 mm,(4x8 mesh) and as powder, and in pellet 1.6",3.2"
