Activated Alumina Desiccant
Activated alumina desiccant is primarily used for deep drying of industrial gas. Its dew-point temperature is -40℃ at definite operating conditions and regenerating conditions. It is a desiccant used for deep drying trace moisture, whereby the moisture is decreased from 10PPM to 2PPM.
Chemical composition (wt%)
- AL2O3 (wt%): 93.5
- SiO2 (wt%): 0.02
- Fe2O3 (wt%): 0.02
- Na2O (wt%): 0.25
Application
Activated alumina desiccant is applicable for the drying of gas and liquid in petrochemical industry, textile industry, production of oxygen, automation instrumentation industry, and PTA/PSA industry.
- This activated alumina desiccant has huge adsorption capacity, and its pulverization is not very easy.
- It has a uniform granularity, smooth surface, high mechanical strength, and great hydroscopicity. It will not swell and break, and will remain unchanged, even after water absorption. It is non-toxic, odorless, and insoluble in water and ethanol.
- Activated alumina is an efficient desiccant suitable for regeneration equipment in non-thermal environments.
