Product Description of 3A Molecular Sieve Desiccant

Selective adsorption based on molecular polarity, unsaturation and polarizability
Molecular sieves have high affinity for polar molecules and unsaturated molecules; Among nonpolar molecules, they have higher selective adsorption advantages for molecules with high polarizability. In addition, the lower the boiling point of the molecule, the less likely it is to be adsorbed by the molecular sieve.


Molecular sieves have high affinity for H2O, NH3, H2S, CO2 and other polymer polarities, especially for water at low partial pressure (even lower than 133 PA) or low concentration, high temperature (even higher than 100 ℃). It still has high adsorption capacity under adverse conditions.


Molecular sieve is the only available high temperature adsorbent. At 100 ℃ and 1.3% relative humidity, the molecular sieve can absorb 15% water. Therefore, at higher temperatures, molecular sieves can still absorb a considerable amount of water.

 

The cracked gas generally contains 400-700ppm of water, which will form ice during cryogenic separation. In addition, under high pressure and low temperature conditions, water can also form white crystalline hydrocarbon hydrate with low-carbon alkanes (such as CH4, C2H6 and C3H8). The crystals of ice and hydrocarbon hydrate can cause blockage of pipelines and equipment, and even cause shutdown.


Therefore, the petroleum cracked gas must be deeply dehydrated and dried before cryogenic separation to reduce the water content in the cracked gas to less than 5ppm (i.e. its dew point is less than - 60 ℃).


At present, the most ideal deep drying adsorbent recognized and commonly used in China is 3A zeolite molecular sieve. Because it only adsorbs water in cracked gas and does not adsorb large hydrocarbon molecules (such as C2H6, C2H4, C3H8, C3H6, etc.), it can avoid coking of olefin compounds in the molecular sieve channels, thus prolonging the service life of the adsorbent.
