Zeolite 3A Ethanol Drying Molecular Sieve
Product Introduction
Our organization insists all along the quality policy of 'product quality is base of business survival; purchaser gratification is the staring point and ending of an business; persistent improvement is eternal pursuit of staff' as well as the consistent purpose of 'reputation 1st, purchaser first' for Silica alumina gel WS for air drying, 5a zeolite for methane CH4 removal, Lithium zeolite for medical. The products to assure years of trouble-free service has attracted a great deal customers. At the same time, we continue to absorb the advantages of outstanding companies in the same industry, improve technical strength, improve the service system, and strive to establish a better image. Our products have novel structure, excellent performance and reliable quality, and are favored by customers all over the world. The core competitiveness of our industries has been continuously improved, which has laid a solid foundation for the realization of high-quality development.
4*8 mesh drying adsorbent molecular sieve 3a for removing moisture.
Chemxin Molecular Sieve type 3A is an alkali metal alumina-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 maximizes lifetime when dehydrating such molecules.

Typical Application |
a) Drying of unsaturated hydrocarbons (e.g. ethylene, propylene, butadien) c) Drying of natural gas, if COS minimization is essential, or a minimum co-adsorption of hydrocarbons is required. |

2. Regeneration:
Chemxin 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.
3. 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.
4. Attention:
To avoid damp and pre-adsorption of organic before running, or must to be reactivated.
