An efficient solution for gas and liquid drying

The BA series consists of activated alumina beads designed for the efficient drying of gases and liquids. Thanks to their highly developed porous structure, they provide a large specific surface area that promotes the adsorption of numerous molecules. This characteristic enables high performance levels, particularly in processes requiring precise humidity control.

These beads are distinguished by their strong adsorption capacity, capable of capturing moisture even under demanding conditions. They remain effective across different temperature ranges and allow achieving very low dew points. Their efficiency makes them an ideal solution for industrial applications related to the drying of compressed air and technical gases.

Common Applications

Drying of compressed air and industrial gases (N₂, O₂, H₂, biogas).

Adsorption of fluoride from drinking water.

Catalyst support (refining, petrochemicals).

Air purification (H₂S, NOx, depending on the treatment process).

High specific surface area

Typically between 200 and 350 m²/g.
Resulting from a highly porous structure (macropores, mesopores).
Facilitates the adsorption of numerous molecules.

High adsorption capacity

Excellent desiccant: captures moisture through absorption and adsorption.
Can achieve very low dew points.
Highly effective even at high temperatures.

High mechanical stability

The beads are highly resistant to abrasion and crushing.
Suitable for fixed-bed or fluidized-bed applications, repeated regeneration cycles, and high gas flow rates.

High thermal and chemical resistance

Withstands a wide range of temperatures (−40 °C to +300 °C under normal use).
Can be regenerated at high temperatures without significant loss of performance.
Good resistance to chemicals (except strong acids).

Advantages of a spherical shape

Smooth and even flow of gases and liquids through the columns.
Reduced pressure drop compared to irregular shapes.
Uniform distribution within the adsorption beds.

Option for specialized treatments

Can be impregnated (with potassium permanganate, metals, etc.) for specialized applications:

fluorine removal,
H₂S removal,
catalysis/oxy-catalysis,
purification of industrial gases.

Long service life

Can be recharged dozens or even hundreds of times, depending on usage.
Minimal structural degradation.

A porous structure optimized for maximum efficiency

Their excellent mechanical stability ensures high resistance to abrasion and crushing. Suitable for both fixed beds and fluidized beds, they can withstand high flow rates and repeated regeneration cycles. Their thermal and chemical resistance allows use across a wide temperature range, with regeneration achieved without significant loss of performance.

The spherical shape of the beads ensures smooth circulation of gases and liquids, reducing pressure drops and promoting a uniform distribution. They can also be treated to meet specific needs such as gas purification, fluorine removal, or as a catalyst support. Their durability and regeneration capacity make them a reliable solution for a wide range of industrial applications.
