Product Overview
Description
Desiccant pellets High adsorption zeolite 3A molecular sieve
Formula:0.4K2O 0.6Na2O Al2O3 2. OSiO2 4.5H2O
REGENERATION
NANXIANG 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 200-230º C is required. A properly regenerated molecular sieve can give moisture dew points below -100º 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, (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.
