Description

Molecular Sieves 3A

Molecular Sieve 3A is an alkali metal alumino-silicate; it is the potassium form of the type A crystal structure. Type 3A has an effective pore opening of about 3 angstroms (0.3nm). This is large enough to allow in moisture, but excludes molecules such as unsaturated hydrocarbons which can potentially form polymers; and this maximises lifetime when dehydrating such molecules.    Item Unit Technical    data Shape   Pellet Sphere Diameter mm 1.**1.7 3.**3.3 1.**2.5 3.**5.0 Size ratio up to grade % ≥*8 ≥*8 ≥*6 ≥*6 Bulk density g/ml ≥0.*8 ≥0.*8 ≥0.*8 ≥0.*8 Wear ratio % ≤0.*0 ≤0.*5 ≤0.*0 ≤0.*0 Crushing strength N *5/cm *0/cm *0/piece *0/piece Static water adsorption % ≥*0 ≥*0 ≥*0 ≥*0 Ethylene adsorption % ≤3.0 ≤3.0 ≤3.0 ≤3.0 Water content, as shipped % ≤1.5 ≤1.5 ≤1.5 ≤1.5   Application 1)      Drying of unsaturated hydrocarbons (e.g. ethylene,propylene,butadiene) 2)      Cracked Gas Drying 3)      Drying of natural gas, if COS minimization is essential, or a minimum co-adsorption of hydrocarbon is required 4)      Drying of highly polar compounds, such as methanol and ethanol 5)      Drying of liquid alcohol 6)      Static (non-regenerative) dehydration of insulating glass units,whether air filled or gas-filled. 7)      Drying of refrigerants
