Add To Favorites ListActivated Alumina For Liquid And Gas Drying
BASF's F200 activated alumina is the industry standard for drying compressed air. Providing long service life with performance at or below dew point specifications, F200 is a peace of mind product for both large and small dryers. It has a high surface area which adsorbs vapors without any change in form, and will not soften or disintegrate easily when immersed in water. Dew points to -40°F and lower may be achieved with activated alumina depending on dryer design and operating conditions.
F200 activated alumina is a porous, smooth sphere of activated oxide produced by BASF’s unique manufacturing process. F200 is an excellent desiccant for drying a wide variety of liquids and gases. Although all molecules are adsorbed to some extent on F200 activated alumina, those molecules having the highest polarity are preferentially absorbed. Stream conditions such as pressure, concentration and molecular weight of the molecules, temperature and site competing molecules affect the efficiency of adsorption. F200 is available in nominal sizes of 1/16", 1/8", 3/16" and 1/4" beads.
Choosing The Right Bead Size
The 1/8" (2-5 mm) bead is the size most frequently used in regenerative dryers. It is also recommended for use in liquid dehydration and other mass transfer limited adsorption applications.
The 3/16" (4-8 mm) bead is used when pressure drop and surface area requirements fall between 1/8" and 1/4" material. It is suitable for most systems and recommended for vapor phase dehydration applications where pressure drop minimization and high water adsorptive capacity are desired.
The 1/4" (5-10 mm) bead size is used both as a pre-bed material to support large desiccant beds or as a buffer for silica gel beads. Pressure drop is slightly lower than 1/8" (2-5 mm) material.
If size is not known or specified, the 1/8" (2-5 mm) size is usually satisfactory. However, if activated alumina is used in a regenerative dryer and the desiccant retaining screens cannot be measured, the 1/4" (5-10 mm) size should be used as a bed support (6" layer).

- Uniform Bead Size. Provides low pressure drop to minimize channeling and ensures utilization of the entire desiccant tower. The uniform size and sphericity prevents adsorbent segregation during pneumatic loading.
- High Crush Strength. Limits dusting and allows rapid pneumatic loading of the desiccant towers. High crush strength makes alumina effective as a pre-bed material when used with other types of desiccants.
- Low Abrasion. Ensures less dusting during transport, loading and tower depressurization. Low abrasion reduces pressure drop and minimizes downstream plugging of the afterfilter.
- High Adsorption Capacity. Reduces initial cost, energy consumption and operating costs through smaller bed sizes and/or longer operating cycles. With high surface area and excellent pore distribution, F200 has a high water adsorption capacity.
