Activated Alumina For Heatless Regeneration Air Dryer
On the Air Dryers, Activated Alumina is filled into A & B tank. They dry the gas by continuous adsorption and desorption. Among which the regeneration function of the dryer includes heating regeneration and heatless regeneration. The heating regeneration which is to desorption activated alumina through high temperature heating, thereby realizing regeneration. Heatless regeneration is based on the principle of pressure swing adsorption. Activated alumina adsorbs moisture under higher pressure and desorption under lower pressure.

Features of activated alumina: Chemxin activated alumina has the characteristics of large adsorption capacity, large specific surface area, high strength, good thermal stability, non-toxic and non-corrosive. It can be widely used as adsorbent, desiccant and catalyst carrier in chemical, petrochemical, natural gas and fertilizer industries.
Packaging
Merthod of Use
1. Do not open the packing before use, in order to avoid moiture absorption, affect the use effect;
2. Activated alumina desiccant is suitable for drying, conditions of use to pressure is grteater than 5kg/cm2;
3. After Activated alumina desiccant used a certain period of time, the adsorption performance will gradually decline, should through the regeneration, removal by adsorption of water, so that repeated used of gas in regenerative operation(with lower than dry homework or identical pressure of dry gas; with higher than dry operations or identical temperature of dry gas; after temperature of wet gas; after decompression of wet gas).
