Activated alumina is a chemically stable, non-toxic desiccant that is useful in numerous applications. In particular, air drying requires activated alumina because its desiccant properties prevent excess compressed air moisture from damaging pneumatic tools and equipment.
Natural gas systems may also utilize antifreeze to avoid the formation of hydrates or free water condensation in gases. Videre, antifreeze may help alleviate corrosion problems along pipelines.
Low Temperature
Activated alumina is a fine spherical aluminum oxide produced synthetically that boasts high crush strength and low dust content, making it suitable for industrial use. Due to its large surface area and porosity, activated alumina makes an effective adsorbent for various liquids, gases, and solids – particularly fluoride removal from water as well as sulfur, arsenikk, lead, and other contaminants reduction. Videre, air and compressed gas drying applications often use activated alumina to dry these types of contaminants off.
Activated alumina’s high crush strength and porosity render it resilient against mechanical stress and thermal shocks, making it more stable than silica gel and suitable for high-pressure applications like air dryers without fear of cracking or breaking under high-pressure applications. Videre, its material characteristics make it safer than calcium sulfate or potassium perchlorate desiccants which may disintegrate due to exposure to high temperatures or hydrocarbons.
Activated alumina desiccants have an exceptional capacity to absorb moisture quickly, making them an excellent choice for compressed air systems. Attracting low pressure dew points down to -40degC, activated alumina ensures air is clean and dry for optimal operation of equipment and machinery alike. However, before selecting this solution for a particular use case it’s still prudent to conduct compatibility tests to make sure there are no surprises down the line.
High Temperature
Activated alumina has the capacity to withstand high temperatures without being affected by the fluctuations found in compressed air and other industrial gases, making it the perfect material choice for air dryers that regularly experience pressure spikes, water vapor emissions and heat accumulation.
High-quality activated alumina desiccants are manufactured with an optimal blend of bulk density, surface area, and permeability that ensures maximum water removal with every cycle. On the other hand, lower quality desiccants may deteriorate over time, decreasing their capacity to remove water while potentially clogging nozzles and gauges and necessitating expensive repairs or replacement costs.
Activated alumina’s unique adsorption properties make it suitable for many different applications that require moisture removal, including pharmaceuticals and chemical processing. Videre, activated alumina acts as a dehydrating agent in natural gas and petrochemical processes, extracting moisture vapor along with hydrogen sulfide gaseous emissions as well as trace impurities like water vapor from gas streams; providing essential moisture control in manufacturing facilities while avoiding costly damage caused by humidity or condensation.
Alumina not only excels at moisture retention, but its superior ability to dry trace amounts of water from liquids like acetone and methyl alcohol is unparalleled. Alumina’s ability to achieve very low dew points in these applications makes it ideal for industrial settings where dirt may present significant challenges.
High Pressure
Activated alumina is a chemically stable material designed to withstand the pressures encountered in industrial drying applications. Produced synthetically as aluminum oxide and heated until porous structures with surface areas greater than 200m2/g are formed with “tunnel-like” pores have formed, activated alumina is an ideal choice.
activated alumina is known for its exceptional crushing strength, making it perfect for use in harsh environments like compressed air drying systems without needing water separation equipment. Videre, this material’s high crush strength enables its application in applications involving high pressures and severe temperatures, such as compressed air drying.
In addition to its adsorption properties, activated alumina is also an efficient desiccant for liquids and gases. It has the capability of drying natural gas and air as well as many liquids. Videre, activated alumina’s low dew points allow it to help dry process streams more efficiently.
Operators using an activated alumina dryer must abide by strict safety and handling protocols. As activated alumina powder is potentially hazardous for inhalation, operators should wear a face shield or mask when handling and prevent eye contact or skin irritation from coming in contact with it. Videre, they should perform compatibility testing prior to using this material for any specific application.
Energy Efficiency
An activated alumina dryer’s energy efficiency is unrivaled in the industry. Absorbing up to 10x more moisture than silica gel without losing strength or capacity, it also features high crush resistance and can withstand various pressures – an invaluable feature when applied in air drying systems that experience regular amounts of moisture vapour and sudden temperature spikes.
Activated alumina is a porous, granular material with large surface area that works effectively at drying compressed air. This desiccant has an exceptional absorption capacity that far outstrips other desiccant materials like molecular sieve.
Activated alumina not only absorbs moisture, but it can also absorb other chemicals and gases present in compressed air streams. Som sådan, activated alumina has applications in industries including chemicals, petrochemicals, and pharmaceuticals.
Personal protective equipment must be worn when handling activated alumina. This includes safety goggles or face shield, chemical-resistant gloves and a dust mask or respirator to reduce any risk from ingestion or inhalation of activated alumina particles which could cause irritation and respiratory problems. Videre, it should be stored away from hydrocarbons and high temperatures.
