Alumina Desiccant Spheres

Alumina Desiccant Spheres Provide Drier Samples, Speed Prep, and Analysis

Sorbtech activated alumina desiccant spheres are very porous. They have a high surface area, which allows the adsorption of gases and liquids, and do not change form.

Activated alumina spheres won’t soften or disintegrate when immersed in liquids. When used to adsorb water, the activated alumina spheres act as an efficient desiccant.

Molecules with the highest polarity are preferentially adsorbed.

In the absence of irreversible fouling, the activated alumina spheres may be regenerated to their original adsorption efficiency by heating to a temperature between 350-600°F (177-316°C).

It is recommended to regenerate the alumina prior to reuse.  To regenerate the alumina it is heated to a high temperature, at low pressure, with dry, inert gas.

Process stream purification
Removal of highly polar compounds such as: TBC, alcohols, ethers, etc.

Acid Removal
Our activated alumina spheres can remove the acids formed from the degradation of trans-former oils, lubricating oils, and refrigerants. Also, they remove the residual halides and water during the manufacture of chlorinated and/or fluorinated hydrocarbons, yielding a non-corrosive product.

Drying
Nearly all gases and liquids can be dried. Water removal is often necessary for efficient processing, storage, transportation, or usage of fluids. For example, water can form hydrates with hydrocarbons, simulating ice, and will plug equipment.

Substances commonly dried with alumina spheres include:

Gases
Acetylene Ethane Hydrogen Chloride Oxygen
Air Ethylene Hydrogen Sulfide Propane
Ammonia Furnace Gas Methane Propylene
CO2 Helium Natural Gas Refrigerants
Chlorine Hydrogen Nitrogen Sulfur Dioxide
Liquids
Benzene Ethyl Acetate Lubricating Oils Refrigerants
Butane Gasolines Naptha Styrene
