F-200 is an activated alumina desiccant designed to quickly dry a variety of liquids and gases, featuring uniform sphere sizes for efficient high pressure gas dehydration with minimal pressure drop, tailored pore distribution offering exceptional dynamic H2O adsorption capacity, reduced dusting due to reduced abrasion levels, as well as high crush strength resistance against amines.
Low Abrasion
BASF F-200 desiccants are industry leaders for drying air and other technical gases. Constructed of smooth spheres of activated alumina that preferentially absorb highly polar molecules, they come in sizes 1/8″, 3/16″ and 1/4″. Although all molecules are adsorbed to some degree, more polar ones tend to be more readily taken up and this allows more effective adsorption under various conditions such as stream pressure concentration and molecular weight.
F-200’s low abrasion ensures less dust during transport and loading, which reduces pressure drop while also helping prevent valve and filter plugging commonly associated with dustier products. En outre, its uniform ball size makes it suitable for high-pressure gas dehydration applications to further minimize pressure drop while its tailored pore distribution ensures high H2O absorption capacity. Other key characteristics of BASF F-200 include high crush strength resistance to amines as well as easy regeneration making this an excellent choice for large as well as small dryers alike.
High Dynamic H2O Adsorption Capacity
BASF F-200 adsorbers are precision engineered, smooth spheres of activated alumina that have been specially engineered to preferentially absorb polar molecules in air streams. While all molecules are eventually adsorbed to some degree, those with higher polarity are absorbed more quickly. Adsorption behavior depends on stream conditions such as pressure concentration and molecular weight as well as other environmental influences such as pressure.
Alkali-containing materials used as adsorbent-desiccants made with e-Al2O3 show significant increases in dynamic water vapour capacity and have positive impacts on material strength, while their increase is related to strong basic sites being formed and reinforced during hydration of Gibbsite thermal activation products.
BASF offers various products for desiccant drying depending on the application, such as F-200 activated alumina, Sorbead AIR silica gels and BASF Molecular Sieves to meet desiccant drying needs. All three achieve dynamic adsorption capacities greater than 20% and reach pressure dew points below -70 degC; when deeper dew points are necessary mixed bed dryers featuring zeolite or carbon monolith 793 can achieve even deeper PDPs than alumina alone can reach.
High Crush Strength
BASF F-200 is an activated alumina sphere produced through a unique manufacturing process. F-200 absorbs liquids and gases of various kinds; molecules with higher polarities tend to be preferentially taken up. Pressure, concentration, molecular weight of molecules being adsorbed as well as temperature and competing molecules all affect its efficiency as an adsorbent material.
F-200’s uniform bead size provides fast pneumatic loading of towers, reduces channeling, and facilitates more effective use of the desiccant bed. En outre, its high crush strength enables dehydration of acid-containing streams such as CO2, while being resistant to amine attack for extended service life compared to alternative dustier products.
With proper tower design and regeneration, adsorption of H2O on BASF F-200 results in ultra low dew point specifications. Thanks to its low abrasion rating, resistance against amines, and dynamic H2O absorption capacity, BASF F-200 makes an excellent choice for drying compressed air.
Resistance to Amines
BASF F-200 Spherical Beads of Activated Alumina are highly resistant to amine attack, making them the ideal solution for gas dehydration applications in high pressure applications where pressure drop minimization is key. En outre, their acid resistance means reduced energy consumption during dehydration processes compared with molecular sieve adsorbents that require higher regeneration temperatures for regeneration purposes.
F-200’s uniform size and sphericity enable it to avoid segregation during pneumatic loading, which reduces channeling while improving overall tower efficiency. Granular or powdered activated aluminas may experience segregation upon loading which leads to poorer performance.
Transformer oils, lubricating oils and refrigerants all generate degradation acids that must be removed in order to make the final product non-corrosive. F-200 can adsorb these acids as well as other polar molecules in order to achieve this goal; in particular it has proven extremely successful at the adsorption of heavy metal ions from hydrocarbons.
Easy Regeneration
Adsorption dryers have become an essential component of every compressed air and energy supply system, yet selecting an adsorption material often gets neglected when selecting the appropriate product for this task. BASF f 200’s ideal combination of properties provides peace of mind to users of large and small adsorption dryers alike; its bead sizes match various requirements such as 7×14 Tyler mesh for dehydration with minimal pressure drop and high H 2O adsorptive capacity as well as 3/16″ beads suitable for liquid or low PDP applications.
