activated alumina ball as desiccants

详情

Activated alumina

Activated alumina has a large capacity of absorption, large surface area, high strength and thermal stability, which is widely used as an absorber, desiccant and catalyst carrier in chemical, petrochemical and fertilizer industry. It can also widely used in the deep drying of cracked gas, ethylene and propylene, hydrogen-generation, air separation, instrument air drying and fluorine treatment for H2O2, also in the absorbing pollution material, such as H2S, SO2, HF and paraffin in the water gas.

Typical Applications

Gas dehydration: Acetylene, Air, Ammonia, Argon, Carbon Dioxide, Ethane, Helium, Hydrogen, Natural Gas, Nitrogen, Propane, Saturated and Unsaturated Hydrocarbon mixtures of various molecular weights
Liquid dehydration: Benzene, Butane, Butene, Bromine Chloride, Carbon Tetrachloride, Heptane, Hexane, HF Alkylation Fed, Napthas, Pentane, Propane, Propylene, Refrigerants, Transformer Oils
Shelf life: Activated Alumina has indefinite storage life if properly stored in dry covered place. Desiccant service life depends on the composition of the stream to be dehydrated, the system and the operating conditions
Our Activated Alumina Balls are low dusting, high capacity desiccant especially for use Hi package dryers.
Activated Alumina Balls have high moisture adsorption capacity
Less energy is required for regeneration. The regeneration temperature is between **0 C to *1OC
It works well in heat less air dryers because of its ease of desorption, high resistance to attrition and high crushing strength
Activated Alumina has excellent thermal stability
For removal of oil vapor from compressed air or gases
For drying compressed air (instrument air)/gases and high pressure air feed to oxygen plant
