Typical Application | a) Drying of unsaturated hydrocarbons (e.g. ethylene, propylene, butadien) b) Cracked Gas Dryingc) 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 ethanole) 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.
