Characteristics:

Molecular sieve 3A, also known as Kalium A molecular sieve, is Kalium ion alkali metal alumino-silicate compound. Its effective pore diameter is 3A (0.3nm), it can selectively adsorb those molecules in fluid which dynamic diameter is less than 0.3nm (such as water molecules, ammonia molecules), lets molecule dynamic diameter more than 0.3nm go through molecular sieve layer bed, and then achieve the aim of fluid mixture. 3A molecular sieve has small aperture, while adsorbs water molecules it can reject all other molecules, thus effectively avoid “total adsorption” phenomena. 3A molecular sieve is a kind of excellent desiccant used for adsorbing water mainly. Yinghe Molecular sieve 3A has quick adsorption speed, high crushing resistance, strong pollution resistance, more regenerative times and long lifespan. It can continue to use after regeneration. 




Applications:

Drying of unsaturated hydrocarbons (e.g. ethylene, propylene, butadien)

Cracked Gas Drying

Drying of natural gas, if COS minimization is essential, or a minimum co-adsorption of hydrocarbons is required.

Drying of highly polar compounds, such as methanol and ethanol

Drying of liquid alcohol

Drying of CNG.

FAQ:

1)What is Molecular Sieve 3A?

Molecular sieve 3A, also known as molecular sieve KA, the potassium based molecular sieve pore size of 3a is 3A0 or 3 Angstrom, it can be adsorb all molecules which having the pore size is less then 3A0

2) What is the main application of Molecular Sieve 3A?

Molecular Sieve 3A is mainly applied for drying of gases and liquids as well as the dehydration of hydrocarbons, also widely used for the complete drying of prtrol, cracked gases, ethylene,propylene and natural gases.

3) Does Molecular Sieve 3A can be regenerated?

Yes, Molecular Sieve 3A can be regenerated. It is based on the pressure, temperature, water of regenerative gas, normally dry gas temperature 180~350?, pressure 0.3~0.5Kg/cm2, through molecular sievebed layer 3-6 hours, exit temperature 110~180?

4) What is the lifetime of Molecular Sieves 3A?

The service lifetime of molecular sieve 3A should be between 24,000-40,000 hours, about 3-5 years which depends on its working conditions of application
