ALUMINA BASF F200 1/8"(3.2mm)

Activated Alumina for Liquid and Gas Drying
BASF F-200 is a smooth sphere of activated alumina produced by BASF’s unique manufacturing process. F-200 is an excellent desiccant for drying a wide variety of liquids and gases. Although all molecules are adsorbed to some extent on F-200 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. F-200 is available in nominal sizes of 1/16", 1/8", 3/16" and 1/4" spheres.

Product Benefits
1. Uniform ball size
This property is especially useful in high pressure gas dehydration where minimizing pressure drop is important. The uniform size and sphericity of BASF F-200 prevents adsorbent segregation during pneumatic loading, thus minimizing channeling and yielding more efficient use of the entire desiccant tower.
2. High crush strength
BASF F-200 has high crush strength which allows rapid pneumatic loading of towers. The high crush strength also allows use of taller towers that make more efficient use of the desiccant. BASF F-200 activated alumina is highly resistant to amine attack. Furthermore, BASF F-200’s high crush strength enables it to dehydrate acid containing gases and liquids, such as CO2, for a longer operating life.
3. Low abrasion
The low abrasion of BASF F-200 ensures less dusting during transport, loading, and service life which reduces pressure drop and minimizes down-stream valve and filter plugging, common with dustier products.
4. High adsorptive capacity
BASF F-200’s high surface area and tailored pore distribution provide a high dynamic H2O adsorption capacity. With proper tower design and effective regeneration, F-200 can achieve an ultra low H2O effluent specification (i.e. dew point). BASF F-200 also has excellent cyclic stability that yields a long life.
