Type A Crystal Zeolite Molecular Sieves 3A For Natural Gas Drying Refining
Product Description of Zeolite Molecular Sieves:
Xi'an Lvneng 3A molecular sieve is an alkali metal aluminosilicate with a pore size of 3A, which is the potassium form of the A-type crystal structure. With a very large specific surface area, it is mainly used to adsorb water, and does not adsorb any molecules with a diameter greater than 3A.
Packing Mall 3A molecular sieve has the advantages of faster adsorption speed, more regeneration times, higher crushing strength, stronger anti-pollution ability, greater utilization efficiency, and longer service life. It is the first choice desiccant necessary for deep drying, refining and polymerization of gas and liquid phases in the petroleum and chemical industries.

Regeneration of Zeolite Molecular Sieves:
Xi'an Lvneng molecular sieve 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 250-300°C is required. A properly regenerated molecular sieve can give moisture dew points below -100°C, or mercaptans or CO2 levels below 2 ppm.
The outlet concentrations on a pressure swing process will depend on the gas present, and the conditions of the process.
Packaging & Shipping of Zeolite Molecular Sieves:
Packing specification: 25kg plastic woven bag or ton bag or bucket packaging, also can be packed according to your requirement.
Product transport requirements: keep dry, away from inflammable, corrodible, toxic goods.
The Attention of Zeolite Molecular Sieves:
1. Xi'an Lvneng molecular sieve desiccant cannot be exposed in the open air and should be stored in dry condition with the air-proof package.
2. Xi'an Lvneng molecular sieve desiccant should be regenerated after a certain period of adsorption. The appropriate regenerated temperature would be better below 350°c.
