molecular sieve 5a for removal CO2 from sour natur

Molecular Sieve 5ais an alkali alumino silicate; it is the calcium form of the Type A crystal structure. Type 5A has an effective pore opening of5 angstroms (0.5 nm). It will adsorb molecules 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 of normal- and iso- paraffins (C4 to C6 species), in PSA hydrogen purification and in oxygen concentrators..Typical Chemical Formula 0.70CaO 0.30Na2O Al2O3 2.0SiO2 4.5H2OSiO2: Al2O3 ≈2Technical ParameterItem UnitTechnical dataShape PelletSphereDiameter mm1.5-1.73.0-3.32.0-3.03.0-5.0Size ratio up to grade %≥98≥98≥98≥98Bulk density g/ml≥0.65≥0.65≥0.70≥0.70Wear ratio %≤0.20≤0.40≤0.20≤0.20Crushing strength N≥30/cm≥45/cm≥30/p≥60/pStatic water adsorption %≥22≥22≥22≥22Water content, as shipped %≤1.5≤1.5≤1.5≤1.5 Application 1) 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 also adsorbed. 2) It is also used for the separation of normal- and iso paraffins. 3)Production of high purity N2, O2, H2 and inert gases from mixed gasstreams. Regeneration Molecular sieve Type5A can be regenerated by either heating in the case of thermal swing processes; or by lowering 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 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 process. Size 5A - Zeolitesare 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”. Attention To avoid damp and pre-adsorption of organic before running, or must to be reactivated.
