Product Introduction
Activated Alumina Desiccant is a highly efficient desiccant with deep absorption of trace water. Because it has uniform size,high strength,low abrasion,strong water absorption ability and stable performance of regeneration and recycling.In certain situations,the dew point of drying depth can be less than or equal to-40℃.Our activated alumina desiccant is mainly used in the drying of gas-liquid products in petrochemical industry.Due to the high net heat of single molecule adsorption layer,it is very suitable for the device without heat regeneration.

Application of Activated Alumina Desiccant
In the air compressor system, activated alumina desiccant is mainly used for deep dehydration of compressed air. When moist air passes through the drying tower, water molecules are adsorbed in the pores of the alumina, reducing the dew point of the outlet air to below -40℃, meeting the drying requirements for instrument air, spraying and other scenarios. In addition, in the production of coatings, it can be added as a dehumidifying agent to the raw materials to prevent the pigments from caking; in the chemical industry, it can also be used as a catalyst carrier or adsorbent to separate trace amounts of water in organic substances.

FAQ
1. How long is the shelf life of activated alumina (drying agent)?
The unopened shelf life is usually 2 years; the actual service life depends on working conditions (such as intake temperature), and is generally 2-6 years.
2. How is activated alumina drying agent regenerated?
After exceeding the shelf life, activated alumina is not completely scrapped. It can usually be regenerated through processes such as re-calcinating to regenerate its adsorption or catalytic properties. This is a relatively low-cost disposal method.
3. How should activated alumina Desiccant be stored?
The storage of activated alumina Desiccant requires special attention to moisture prevention, sealing, and avoiding contamination to maintain its adsorption performance and extend its service life.
