Activated Alumina for Drying in Air Seperation

Activated alumina for drying in air seperation is a high surface area, highly porous form of aluminum oxide. It adsorbs gases and liquids without changing its form. It works as a desiccant by adsorption. As air passes through the alumina, water in the air bonds and becomes trapped on the AA desiccant beads. Air that passes through an activated alumina filter or dryer can achieve -40 or -100 dewpoints. AA desiccant will not fall apart or soften if exposed to water.

Even if immersed in a liquid, Activated Alumina Desiccant won't fall apart or soften. You can restore the original adsorption efficiency of activated alumina by heating it to any temperature from 177° to 316°C. 

Widely used in iron and steel, textiles, electronics industry, oil cracking gas, PVC, acrylic casing in dry gas, liquid depth and purifying agent, pressure swing adsorption of air separation industry desiccant, etc. Activated Alumina Desiccant can dry almost all liquids and gases. To achieve efficient storage, transportation, and processing of fluid, it's often necessary to remove water.
