Drying Compressed Air with Activated Alumina

Over the years, the commercial drying conditions have become more demanding with customers outlining the pressures, velocities and regeneration frequencies for their air service. To satisfy these needs, different formulations of activated alumina are used for removing the water from air and other gases. It is a prominent way to dry compressed air and gases with relatively high humidity. The major reasons for its widespread acceptance in various applications are physical and chemical resistance, low cost, and a high capacity to retain water and regenerability.

Activated Alumina F200

Being an excellent desiccant, it is basically a smooth sphere of alumina produced by a unique manufacturing process for drying a variety of gases and liquids. The molecules with high polarity are preferentially adsorbed on it, whereas many stream conditions like concentration, pressure and molecular weight of the molecules affect the adsorption efficiency. F-200 is rapidly becoming an ideal product for both small and large dryers in the following areas:
Acid removal: During the manufacturing of fluorinated or chlorinated hydrocarbons, various acids are removed using this compound, resulting in a product which is completely non-corrosive.also Check our Latest article here:Oxygen Absorbers | Food Storage | O-Buster Suppliers

Hydrocarbon adsorption: The surface chemistry and pore size distributions of Air Drying Activated Alumina play an important role in the adsorption of any hydrocarbon.

Process steam purification: It is an excellent material for the removal of any polar compounds like alcohol and water. It also readily adsorbs heavy metal ions and TBC from hydrocarbons.

Drying: As removal of water is necessary for efficient storage, processing and transportation of fluids, F-200 can be readily used in these applications to dry almost all gases and liquids.

Advantages of F200

The following properties make it an ideal product for many industries:
Low abrasion: This property makes sure that there is less dusting during loading, transport and service life, which, in turn, minimizes the filter plugging and downstream valve, an issue quite common with dustier products.

High crush strength: A high crush strength of Activated Alumina F200 allows rapid loading of towers and their use as taller towers, which makes desiccant to be used more efficiently. This property also enables it to dehydrate any acid containing liquids and gases for a relatively longer operating life.

Uniform size of the ball: The uniform sphericity of  these balls prevents segregation of adsorbent during pneumatic loading, thereby minimizing the channelling and yielding more efficient use of the entire desiccant tower.
High adsorption capacity: The high surface area of this compound provides high H2O adsorption capacity.

Based on the above points, it is evident that this is the best all purpose desiccant for drying most of the gases with relatively high humidities and air.
