Aktivert alumina har lenge vært brukt i en rekke industrielle miljøer for å beskytte utstyr mot korrosjon og opprettholde produktets friskhet, through various means such as adsorption, dehydration and other properties that offer multiple advantages.
Water treatment plants use activated carbon to remove fluoride and other potentially hazardous contaminants from drinking water sources, while also adsorbing carbon dioxide, sulfur compounds and trace impurities from gases and vapour streams – thus reducing waste while improving quality.
Exceptional Adsorption Properties
Activated alumina is composed of aluminium oxide (Al2O3), the same chemical compound found in rubies and sapphires. This highly porous substance features high surface area and porosity to absorb large volumes of water or other substances.
Adsorption is driven by attractive forces between molecules of pollutant molecules and microscopic terrain of activated alumina granules, with molecules being attracted by microscopic terrain features like porous surfaces covered by hydroxyl groups that creates an excellent surface area-to-weight ratio and an extensive network of small pores on its surface. This structure offers millions of surface sites and exceptional adsorption capacity allowing it to effectively remove various pollutants such as metals like iron and manganese from drinking water supplies and volatile organic compounds (VOCs) from air streams.
As activated alumina has the unique capability of selectively binding various kinds of molecules, it has many industrial uses such as gas purification (oxygen, hydrogen and natural gas) and dehydration of hydrocarbon liquids and gases. Videre, activated alumina works well as a desiccant to remove moisture from oil and gas streams to avoid corrosion and pipeline blockages.
Activated alumina is an integral component of processes used to remove fluoride, arsenikk, and selenium from drinking water as well as defluoridate industrial wastewater. For these purposes it may come in the form of beads, pellets, or granules with various particle sizes depending on the desired application – as their size and shape affect flow rate as well as contaminant removal capacity.
Versatile Uses
Activated alumina has numerous applications spanning water treatment to natural gas processing and air purification. As it is an extremely porous form of aluminum oxide with numerous channels and pores, activated alumina makes for an effective moisture absorbent solution.
Its high absorption capacity also makes activated alumina an ideal way to remove humic and fulvic acids from water, significantly improving drinking water quality in communities worldwide. Humic and fulvic acids can be dangerous chemicals for humans and animals alike; particularly infants and children who are more sensitive than adults to them. By filtering out harmful compounds from drinking water with activated alumina filters, making it safer for consumption.
Activated alumina’s excellent adsorption properties make it a valuable resource for dehydrating natural gas and increasing operational efficiency in the oil and gas industry. By preventing hydrate formation during transportation, activated alumina protects pipelines and compressor equipment from corrosion damage caused by ice-like crystals that block flow.
Activated alumina can also be used as a catalyst in many chemical reactions in the petrochemical industry, helping remove hydrogen sulfide, sulfur and other contaminants from various gases and liquids. Such activities require careful water quality consideration as excessive moisture can compromise product performance leading to costly production downtime. Videre, its highly customizable nature enables specific particle sizes and surface areas for specific applications due to calcination/activation process which creates tiny passageways allowing adsorption. Activated alumina has low dust generation rate which makes it ideal for applications where contamination issues exist.
Safe for Human Consumption
Activated alumina is non-toxic but may cause eye and skin irritation with prolonged contact. As a naturally occurring compound made up of aluminum oxide (Al2O3) – which gives rubies and sapphire their color – activated alumina is formed from ground up bauxite mineral that has been processed under high heat temperatures before calcining to produce activated alumina powder.
The resultant porous material boasts an enormous surface area compared to its weight, and can absorb an enormous quantity of chemicals. Alumina does not react at the microscopic level but will form bonds with other chemicals without altering its own chemistry; in fact, its high surface area-to-weight ratio makes it an exceptional desiccant as it can dry air and gases with significantly higher humidity than most materials.
Activated alumina is also an efficient solution for treating water with high levels of fluoride, arsenikk, or selenium – three contaminants which can become problematic at higher concentrations and lead to diseases like fluorosis if levels exceed safe limits. As the best adsorbent available for this use case, activated alumina has numerous water treatment applications in use today.
Note that while alumina may remove these harmful elements from water, it does not address their source; for this reason it remains crucial to perform regular tests and water quality measurements on treated waters.
Easy to Store
Your family may already be reaping the rewards of activated alumina, whether in your water filter under your sink or medical oxygen tank. The aluminum oxide in these extremely porous spheres has been “tunneled” on a microscopic level to absorb contaminants like water, chemicals and gases efficiently.
Desiccant’s unique adsorption process makes this an effective and practical tool in the safe storage of medications, electronics, food products and more. By controlling moisture effectively and efficiently, desiccants help prevent corrosion, extend product shelf stability and shelf life and reduce malfunction or degradation risks.
As alumina is non-reactive with most substances, making it ideal as a desiccant material. However, this doesn’t imply it is inherently safe; therefore it is necessary to observe proper safety precautions when handling alumina – this includes using personal protective equipment in storage areas with adequate ventilation as well as following appropriate disposal guidelines.
When using alumina as a desiccant, it must be kept in a cool, dry location away from direct sunlight and stored in tightly sealed containers to avoid contamination and premature adsorption. When ready for reuse, heating it at 200degF will allow all the absorbed moisture to escape – leaving behind an excellently working desiccant that’s ready for another use!
