Technical Data Sheet Model 3A Color Light gray Nominal pore diameter 3 angstroms Shape Sphere Pellet Diameter (mm) 1.7-2.5 (8*12 mesh) 3.0-5.0 (4*8 mesh) 1.6 (1/16 inch) 3.2 (1/8 inch) Size ratio up to grade (%) ≥98 ≥98 ≥96 ≥96 Bulk density (g/ml) ≥0.70 ≥0.70 ≥0.68 ≥0.68 Wear ratio (%) ≤0.20 ≤0.20 ≤0.40 ≤0.40 Crushing strength (N) ≥35/piece ≥85/piece ≥30/piece ≥50/piece Static H2O adsorption (%) ≥21 ≥21 ≥21 ≥21 Ethylene adsorption (‰) ≤3.0 ≤3.0 ≤3.0 ≤3.0 Water content (%) ≤1.5 ≤1.5 ≤1.5 ≤1.5 Typical Application a) Drying of unsaturated hydrocarbons (e.g. ethylene, propylene, butadien) b) Cracked Gas Drying c) Drying of natural gas, if COS minimization is essential, or a minimum co-adsorption of hydrocarbons is required. d) Drying of highly polar compounds, such as methanol and ethanol e) Drying of liquid alcohol,CNG. f) Static, (non-regenerative) dehydration of insulating glass units, whether air filled or gas-filled. g) Drying of CNG. Regeneration: Guangdong Xintao molecular sieve Type 3A 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 3A molecular sieve, a temperature of 200-230°C is required. A properly regenerated molecular sieve can give moisture dew points below -60°C.The outlet concentrations on a pressure swing process will depend on the gas present, and on the conditions of the process. Size: 3A - Zeolite 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 1.6mm, 3.2mm. Attention: To avoid damp and pre-adsorption of organic before running, or must to be reactivated.
