Adsorbent dryer series

4A Zeolite Absorbent

The zeolite is a kind of crystalline aluminosilicate. It has many excellent features because it has a uniform pore diameter and high specific surface area. It has a strong water absorption. Even if it is under a higher temperature, a larger airspeed and a low water content, there is still a relatively high absorption capacity.

High Efficiency Type NaY Absorbent

NaY absorbent uses NaY zeolite as its active component. Compared with the 4A zeolite absorbent, its silica-alumina ratio is higher and the effective aperture is bigger. Otherwise, the selectivity, the adsorbing capacity, the thermal stability and the acid resistance are also better.

Industrial Application

The products can be widely used in petrochemical industry, fine chemistry and natural gas processes, absorbing water and CO2 of feed gas in air-separating equipment, shielding gas in the process of purified heat treatment, removing water and sulfur dioxide in natural gas and deeply dry the common gas in industry and substance separation. The NaY absorbent also has the ability to absorb the molecular which is less than critical diameter, like aromatic hydrocarbon and branched chain hydrocarbon.
