Activated alumina AD101, also known as desiccant, catalyst carrier, de-fluorination, adsorbent and aluminum oxide, has a highly porous structure which allows it to showcase its pole-molecular absorbent nature, in addition to several outstanding features like high absorbent rate and high selectivity. It is important for industries of all kinds to utilize desiccants for reducing the operating cost and the overall energy consumption. Due to its property to dry out the gases easily, activated alumina has become immensely popular in all parts of the world.

Moisture is removed from the gases so as to avoid several undesirable effects that are caused by ice and liquid formation, catalyst contamination and corrosion. There are some basic water removal steps that appear in various applications, including industrial gas drying and air conditioning. The activated alumina figures allow the gas streams to keep the gases away from moisture so that physical and chemical resistance can be minimized.

High Mechanical Strength

Gas Drying Activated Alumina is required to have a high mechanical strength so that it can withstand processes like crushing and attrition. The crushing and attrition values for various spheres those are well adapted towards the applications.

Major Applications

• Drying of gases, including catalytic reforming recycle gas, cracked gas, LNG and natural gas

• Drying up of basic gases, including CO2, nitrogen, oxygen and hydrogen

• Purification of liquids and gases

• Air separation and air drying

• Activated alumina for the purpose of hydrogen-generation

• Gas drying activated alumina utilized for fluorine treatment for H2O2

Benefits and Features of Gas Drying Activated Alumina

• There is low abrasion for a lesser amount of dusting and drying during the process of depressurization.

• Activated alumina even reassures low pressure drop and a reduced opportunity of plugging a powerful alter-filter.

Activated Alumina AD101 won’t swell, soften or shrink, even when it is completely immersed in water. It is not affected by water slugging, which is why the alumina beads don’t get fractured easily. Another major benefit of this desiccant is that its high adsorption capacity allows it to get restored just after the regeneration process gets over.

• In large drying systems that are regenerative, the activated alumina beads do have a long shelf life due to their natural properties.
There are various different types of activated alumina and it’s important for the user to choose the right one that offers maximum benefits at once.

In spite of having so many gas drying desiccants out there in the market, there has a strong significance why people (those who need to use these desiccants) are fond of activated alumina when it comes to dry out a warm gas appropriately. One of the prime reasons is that these balls are formulated with aluminum oxide which is highly porous and possess a tremendous surface area which let them soak up the gas and water molecules on a large scale. The surface normally ranges from 345-415 square meter/gm and this wide surface makes this element adsorb more gas, moisture, water vapor and humidity, even more than silica gel as well. For having such a higher capacity of gas consumption at an elevated temperature as well, it is an obvious choice for the various industrial purposes like; purification, isolations etc.

The alumina has a resistant power from thermal shock and abrasion, more so, they don’t get shrink, swell, soften and not even they disintegrate when completely saturated into gas. The element is formulated with aluminum hydroxide and the process is called dehydroxylation. Successful accomplishment of the process results in production of highly porous material with a huge surface area. It is made of aluminum oxide (Al2O3) and exhibits a high surface area compare to its weight and because of these, it has lots of small pores which run throughout it.

This Gas drying activated alumina is generally used for warm gases like hydrogen sulphide, sulfur oxide etc. including air as well because it has higher water absorption capacity even at a high temperature. This chemical substance doesn’t make so much of physical changes after getting immersed into gas molecules. Despite being used as an adsorbent, the activated form of alumina also possess catalyst applications in the form of alumina balls which includes the absorption of catalyst in the production of polyethylene. The utilization of activated alumina AD101 ranges from the purification (mainly removing metallic traces, TBC and HF compounds) of gases and liquids, drying out organic liquids such as LPG, propylene, butane etc.

The desiccation of gases includes steam cracked gases, catalytic reforming gases, synthesis gases, methyl chloride and natural gases etc. and it also dry out oxygen, nitrogen, hydrogen, CO2. The most enchanting fact is that this form of alumina can be regenerated when it is entirely drenched with gas molecules by heating up the alumina at around 2000C as it releases the gas molecules at then.

A tremendous growth in the industrial area all over the world has been witnessed over the last few decades. The growth of any industry is directly proportional to its products and successful manufacturing of those products depends on various other elements. There are a number of natural effects that can cause significant impact on any industry and to its products as well. Water or moisture in the air is one such reason that may cause damage to the products related to chemical industry, pharmaceutical industry, food industry, electrical industry etc. In order to keep the products safe from moisture and water, various adsorbents or desiccants are used.

Now what are these desiccants? A desiccant is a substance that is used to remove water or moisture or for the purpose of purification of any particular product and any mixture of different substances. Different kinds of desiccants are used for different purposes. Some of those desiccants are silica gel, alumina oxide, zeolite, etc. The application of alumina oxide as a desiccant is largely seen in the industrial sectors. The best part of these desiccants is they don’t create any sort of reaction with any compound. These adsorbents (desiccants) are tasteless, odorless and are normally available in different forms other than solid one.

Activated-Alumina

Talking about the desiccants, the name activated alumina is bound to arise since it is one of the most effective and well-known adsorbents, used in various industrial areas. It is basically a form of aluminium oxide and is widely used to keep important industrial products away from the effects of moisture and water. Alumina is vastly used for the purification of different complex mixture of compounds and for dehydration of compounds. There are lots of structural differences between alumina and silica gel which makes alumina a comparatively effective adsorbent for purification or dehydration.

Activated alumina is used for warm gas drying activated alumina because of its capability to work absolutely fine as a water adsorbent in higher temperature as well. This alumina is available in different sizes and in different specifications. Depending on the purpose and the nature of the substances need to be separated those specifications are applied. When it comes to adsorbing water from organic liquids such as LPG, Propylene, gasoline, steam etc, alumina is considered as the most preferred choice. Some of the features of these alumina balls are they are highly resistant to thermal shock, the surface area is excellent. They never shrink or swell in the water, they work completely fine at higher temperature.
Alumina is vastly available through online now. Numerous reputable adsorbents manufacturing companies are now offering their products through online now for the convenience of the industries.
