BASF F-200 is an activated alumina desiccant that preferentially absorbs highly polar molecules to help produce air with extremely low dew point specifications.
With its high crush strength, these panels can be pneumatically loaded into towers with minimal pressure drop. Plus, their resistance to amine attack and low abrasion ensure long service lives.
Suitable for a wide range of applications
Activated alumina is a dry granular chemical produced through dihydroxylation of aluminum hydroxide. It bonds easily to liquids and gases without altering their chemical or physical properties, resisting thermal shocks without swelling or disintegrating when immersed in water, being highly acid- and alkaline-resistant and regenerable through use of NaOH or H2SO4 solutions.
Oil and gas industries, water treatment facilities and healthcare organizations rely heavily on reverse osmosis filters for fluoride removal from drinking water supplies. Regeneration methods include treating it with sodium hydroxide and sulfuric acid solutions or heating to 600 degC to release water molecules back into solution.
Market growth is being propelled by widespread product adoption in refinery projects and an expanding lithium industry, and by its ability to purify lithium used for applications like glass, ceramics, batteries and lubricating greases. BASF molecular sieve adsorbents are specifically tailored for low dew point cryogenic environments because of their lower energy consumption, higher operating efficiency and longer lifetime compared to alternative technologies – this makes them especially suitable for low dew point and cryogenic conditions.
High crush strength
Activated alumina is an aluminium oxide with many tunnel-like pores, giving it a high surface area-to-weight ratio and making it very porous. As such, activated alumina is often used as a desiccant to absorb excess humidity from air while filtering fluoride out of drinking water, and can even be regenerated via dissolution in either sodium hydroxide (NaOH) or sulfuric acid (H2SO4) solutions.
Interra Global provides BASF DD-6, an exceptionally high surface area alumina designed to aid hydrogen peroxide production. This material reduces degradation during deepoxification, decreases quinone retention on spent product, and optimizes performance during Claus catalyst processes by adsorbing oxygen.
BASF F-200 Spherical Activated Alumina (SAA) is an industry-leading solution for drying various liquid and gas streams, including compressed air streams. Due to its uniform size and sphericity, rapid pneumatic loading of towers with it minimizes channeling while yielding more effective use of its entire desiccant. In addition, its high crush strength resists amine attack while its low dust content makes it a suitable option for dehydrating compressed air at or below specified dew point specifications.
Low abrasion
Activated alumina is a porous granular chemical which bonds with liquids and gases without altering their chemical or physical state, making it an excellent desiccant in oil & gas applications where it can adsorb distillate vapors as well as trace moisture found in natural gas streams. Furthermore, activated alumina is commonly employed in water treatment industry to remove contaminants such as arsenic and fluoride from source waters.
BASF F-200 activated alumina is constructed from engineered spheres which preferentially absorb highly polar molecules, leading to low H2O effluent specifications even under challenging stream conditions. Furthermore, its superior abrasion resistance reduces dust during transport and loading operations; minimising downstream valve and filter plugging common among dustier products.
The global activated alumina market is dominated by several large vendors, such as BASF SE of Germany, JM Huber Corporation of the US and Honeywell International Inc of US respectively; Sumitomo Chemical Co Ltd from Japan; Porocel Industries LLC in US from USA as well as Axens SA France Dynamic Adsorbents Inc USA USA KIN Filter Engineering Co Ltd India among many others. All these players invest extensively in research and development activities for eco-friendly solutions.
High dynamic H2O adsorption capacity
The dynamic adsorption capacity of activated alumina depends on regeneration conditions. Results demonstrate that increasing regeneration temperature leads to improved moisture adsorption while ultrasound enhances regeneration, leading to an increase in specific surface area that increases its dynamic adsorption capacity and thus increase its dynamic adsorption capacity.
Demand for activated alumina globally has increased due to increased investments in wastewater treatment and recycling infrastructure, along with stringent arsenic removal standards in North America and Asia. Furthermore, the petrochemical industry is also increasingly demanding activated alumina for gas drying applications.
Activated alumina is an outstanding desiccant, suitable for various liquids and gases, with its high absorption capacity making it suitable for many industrial processes. Furthermore, its excellent resistance to thermal stress and abrasion make it suitable for chemical and pharmaceutical applications; its thermal stability makes it the ideal choice when considering bio ceramic implants as dental or bone implant components. Furthermore, activated alumina also features excellent acid/base resistance qualities, making it suitable for harsh chemical processing environments.
Low dew point
Sorbead Air R, F-200 activated alumina and molecular sieve desiccants offer significant energy savings when operating under conditions where compressed air dryers have lower pressure dew points, thus making use of these desiccants possible for drying of compressed air and other technical gases.
Activated alumina has an excellent affinity for water molecules, making it an efficient desiccant in many applications. Furthermore, its excellent absorption capacity and crush strength make it suitable for use in compressed air systems.
This adsorbent can also be utilized in filtration and column chromatography to filter contaminants out of liquids and gases, while its low dew point capability enables it to dry compressed air purifier and protect sensitive equipment from moisture damage.
Though activated alumina is generally inert, its ingestion should be avoided as large doses may lead to lung irritation and should always be stored in a cool, dry location in order to avoid premature water adsorption and degradation of its material.
