Activated Alumina For Air Drying

Good maintenance and purity of products is the need of all manufacturing industries in today’s days.The best solution to this,is the use of Activated Alumina.It comes out as a best product in this time and zone with effective maintenance properties.Activated alumina is prepared by the dehydroxylation process using aluminium hydroxide as the chief material.It is basically a dessicant that has a high degree of porous material.The main role of these dessicants is to absorb the moisture,water vapor,humidity,odor etc.The dessicants are available in a variety of types which makes it possible for purifying,drying as well as cleaning the air in cost effective manner.It makes it more stronger and thereby reduces the chances of contamination.Activated alumina finds a wide range of applications including water purification and industrial air drying. The activated alumina balls are used for heated air drying and for van drying.

METHODS:

The molecular sieves with high content of sodium alumina silicate beads has a pressure dew at the point of -100 degree Fahrenheit whereas the silica gel can also be used as absorbent at a dew point of -40 degree Fahrenheit. Hence,the activate alumina balls will have the almost same dew point in the range of -40 to-100 degree Fahrenheit.They are available in different bead sizes such as 1mm to 8mm.They are efficient for some of the processes like heated,compressed,heatless and also for the refrigerated type of air drying activated alumina applications.

One more alternative process include the Molsiv adsorbent alumina balls as the Aluminium oxide compound is resistant towards thermal shock,abrasion,highly porous surface area and many others.The alumina balls have high water carrying capacity and will never sink when immersed in water.The balls do not swell,disintegrate and soften when in comes in contact with water.They retain their properties with rising temperature compared to silica gel.Activated alumina AD101 has the best high level of dehydration rate.

APPLICATIONS:

Activated alumina balls find a wide range of applications including fluoride water filter,tower packing,column internals,air drying and many more. Besides they are extremely useful in purification of liquids and gases,drying of gases like oxygen,hydrogen,nitrogen,carbon-dioxide and many more.They are also useful in natural gas productions for the compression plants,LPG,LNG etc.

Drying Compressed Air with Activated Alumina

Over the years, the commercial drying conditions have become more demanding with customers outlining the pressures, velocities and regeneration frequencies for their air service. To satisfy these needs, different formulations of activated alumina are used for removing the water from air and other gases. It is a prominent way to dry compressed air and gases with relatively high humidity. The major reasons for its widespread acceptance in various applications are physical and chemical resistance, low cost, and a high capacity to retain water and regenerability.

Activated Alumina F200

Being an excellent desiccant, it is basically a smooth sphere of alumina produced by a unique manufacturing process for drying a variety of gases and liquids. The molecules with high polarity are preferentially adsorbed on it, whereas many stream conditions like concentration, pressure and molecular weight of the molecules affect the adsorption efficiency. F-200 is rapidly becoming an ideal product for both small and large dryers in the following areas:

Acid removal: During the manufacturing of fluorinated or chlorinated hydrocarbons, various acids are removed using this compound, resulting in a product which is completely non-corrosive.

Hydrocarbon adsorption: The surface chemistry and pore size distributions of Air Drying Activated Alumina play an important role in the adsorption of any hydrocarbon.

Process steam purification: It is an excellent material for the removal of any polar compounds like alcohol and water. It also readily adsorbs heavy metal ions and TBC from hydrocarbons.

Drying: As removal of water is necessary for efficient storage, processing and transportation of fluids, F-200 can be readily used in these applications to dry almost all gases and liquids.

Advantages of F200

The following properties make it an ideal product for many industries:

Low abrasion: This property makes sure that there is less dusting during loading, transport and service life, which, in turn, minimizes the filter plugging and downstream valve, an issue quite common with dustier products.

High crush strength: A high crush strength of Activated Alumina F200 allows rapid loading of towers and their use as taller towers, which makes desiccant to be used more efficiently. This property also enables it to dehydrate any acid containing liquids and gases for a relatively longer operating life.

Uniform size of the ball: The uniform sphericity of  these balls prevents segregation of adsorbent during pneumatic loading, thereby minimizing the channelling and yielding more efficient use of the entire desiccant tower.

High adsorption capacity: The high surface area of this compound provides high H2O adsorption capacity.

Based on the above points, it is evident that this is the best all purpose desiccant for drying most of the gases with relatively high humidities and air.

Air drying activated alumina – the safest way to purify liquids and gas products

Moisture often plays an adverse role in the safety of various industrial products. It is almost axiomatic that moisture or water can have a huge impact on the quality and nature of the products especially when it is a pharmaceutical product or electronic product. Pharmaceutical products or medicines are mainly made of different chemical ingredients that can cause reaction with moisture or water. Thus the key quality of the medicines may get damaged. This is why a perfect adsorbent and desiccant are so much important for maintaining the quality and nature of the products. There are many different types of adsorbents available in the market that are available for different purposes but the most effective and well-known of them all is activated alumina. 

This is one of the best and widely used desiccants of the present time. In many industrial sectors, this desiccant is used massively. It is mostly used for purifying and adsorbing moisture from the air and for dehydrating the ingredients or products. It is basically a form of aluminium oxide with wider surface and it is highly porous which makes this desiccant usable for wide range or purposes. Its adsorbing capacity and crushing strength have been appreciated in many industries. The key application of this desiccant is purification, separation and dehydration of various gases and liquids. When immersed into water it doesn’t get shrunk or disintegrated.

There are numbers of features of activated air dying alumina which make this highly preferable in various industries. One of the key features is its surface area. Due to excellent surface area, this can absorb more moisture or water from the air and this quality is accompanied by good adsorption ability. Another advantageous factor is its pore size that is comparatively larger than any other popular desiccants. When compared to silica gel, this desiccant has more capacity to absorb water at a higher temperature. This has also outdone the application of Zeolites in a number of industrial sectors. Activated alumina is available in the form of small balls which are known as activated alumina balls.

In most of the occasions, two types of activated alumina which are activated alumina AD101 and F200 are used for the purification of various gases and liquids. Organic liquids such as LPG, propylene, aromatic solvents, gasoline are dehydrated with the use of this adsorbent. And the best part is presently with more companies providing their service through online, users can get hold of this desiccant through internet. Irrespective of the quantity and the purpose of use, users can purchase these balls from online. All they need to be careful about with the different grades and specifications of the balls.
