5A Molecular Sieve detail

Introduction

5A Molecular Sieve is an alkali alumino silicate;5A Molecular sieve is the calcium form of the Type Acrystal structure. 5A Molecular Sieve has an effective pore opening of 5 angstroms (0.5

nm). 5A Molecular sieve will adsorb molecules with a kinetic diameter of less than 5 Angstrom andexclude those larger.5A Molecular Sieve is especially suitable for PSA adsorber applications where it may be used for the

separation of normal- and iso- paraffins (C4 to C6 species), in PSA hydrogen purification and in oxygenconcentrators.

Typical Chemical Formula0.7 CaO . 0.3 Na2O . Al2O3 . 2 SiO2 . 4.5H2O

Application The strong ionic forces of the divalent calcium ion makes it an excellent adsorbent to remove water,

CO2, H2S from sour natural gas streams, while minimising COS formation. Light mercaptans are alsoadsorbed.

It is also used for the separation of normal- and iso paraffins. Production of high purity N2, O2, H2 and inert gases from mixed gas streams.

Regeneration

5A Molecular sieve can be regenerated by either heating in the case of thermal swing processes; or bylowering the pressure in the case of pressure swing processes.

To remove moisture from a 5A molecular sieve, a temperature of 250-300°C is required. A properlyregenerated molecular sieve can give moisture dew points below -100°C, or mercaptan or CO2 levelsbelow 2 ppmv.

The outlet concentrations on a pressure swing process will depend on the gas present, and on theconditions of the process.

Size5A Molecular Sieve are available in beads of 1-2 mm, (10x18 mesh) 2-3 mm, (8x12 mesh) , 2.5-5 mm,

(4x8 mesh) and as powder, and in pellet 1.6”, 3.2”.
