Description

3/16" (4-8mm) bead activated alumina is used when pressure drop and surface area requirements fall between 1/8" and 1/4" material. It is suitable for most systems. Activated alumina is a porous form of aluminum oxide. It has a high surface area which adsorbs vapors without any change in form.

If size is not known or specified, the 1/8" (2-5mm) 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" (5-10mm) size should be used as a bed support (6" layer).

The industry-standard activated alumina desiccant is used extensively in compressed air dryers. Activated alumina is for use in both heated compressed air dryers and heatless / pressure swing compressed air dryers. Dewpoints to -40°F and lower may be achieved with activated alumina depending on dryer design and operating conditions. F-200 is a smooth sphere of activated alumina produced by the 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.

Benefits

Features

1. HIGH MOISTURE CAPACITY: The high surface area and excellent pore distribution combine to give PSI activated alumina a high water adsorption capacity. This feature of PSI activated alumina reduces investment, energy con-sumption and operating costs through smaller bed sizes or longer operating cycles.

2. SMOOTH BEADS/ LOW ABRASION: Ensures LESS DUST-ING during tower loading and depressurization. Low abra-sion means lower pressure drop and less chance for plugged or clogged pore orifices, valves or filters due to dust carr yover. (LOW PRESSURE = LOW DUSTING = BET-TER PERFORMANCE)

3. UNIFORM SIZE = LOW PRESSURE DROP In a packed bed, PSI activated alumina provides a low pressure drop which minimizes channeling and maximizes utilization of the whole drying capacity of the tower.

4. UNAFFECTED BY LIQUID WATER: Water slugging due to upstream failure of aftercoolers, moisture separators, drain traps or filters will not fracture PSI activated alumi-na. Adsorption capacity of saturated desiccant can be restored after a complete regeneration cycle.

5. HIGH CRUSH STRENGTH: This feature of PSI activated alumina limits dusting when loading towers. A high crush Its strength makes activated alumina a good pre-bed material for use with other types of desiccants in mixed towers.

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 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
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. F-200 activated alumina is highly resistant to amine attack. Furthermore, 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 F-200 ensures less dusting during transport, loading, and service life which reduces pressure drop and minimizes downstream valve and filter plugging, common with dustier products.

4. High Adsorptive Capacity
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). F-200 also has excellent cyclic stability that yields a long life.

Applications

1. Drying
Nearly all gases and liquids can be dried with F-200. Water removal is often necessary for efficient processing, storage and transportation of fluids. The 3/16" size is normally recommended for vapor phase dehydration applications where pressure drop minimization yet high H2O adsorptive capacity is desired. The 1/8" and 7 x 14 Tyler mesh sizes are recommended for use in liquid dehydration and other mass transfer limited adsorption applications.

BASF F-200 activated alumina is rapidly becoming the industry standard for drying compressed air. Providing long service life with performance at or below dew point specifications, F-200 is a 'peace of mind' product for both large and small dryers. BASF F-200 is appropriate for use in dehydrating gases in both thermally regenerative (350 to 600°F) and pressure swing (PSA) modes.

2. Acid Removal
Transformer oils, lubricating oils, and refrigerants form degradation acids upon use. BASF F-200 will remove these acids during use. In the manufacture of chlorinated and/or fluorinated hydrocarbons, removal of these residual halides and water is essential for a non-corrosive product.

3. Process Stream Purification
BASF F-200 is excellent for removal of highly polar compounds such as water and alcohol. It also readily adsorbs TBC ad heavy metal ions from hydrocarbons.

4. Hydrocarbon Adsorption
Under proper operating conditions, the pore size distributions and surface chemistry of activated aluminas are conducive to the adsorption of hydrocarbons.
