Regeneration of 3A Molecular Sieve
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 -100°C. The outlet concentrations on a pressure swing process will depend on the gas present, and on the conditions of the process.
Size
3A – Zeolites are available in beads of 1-2 mm(10×18 mesh), 2-3 mm(8×12 mesh), 2.5-5 mm(4×8 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.
