ACTIVATED ALUMINA BALLS

The basic prerequisites for solid desiccant dehydration are that the desiccant be able to withstand the stream to be dried and that the stream composition and properties remain unchanged after water removal. Noble Activated Alumina performs well by these standards when used to dehydrate gases & liquids of many types. The dehydration process can be made cyclic by taking advantage of the ability of activated alumina to be regenerated thermally. The service life of activated alumina can be up to many years. Replacement of the desiccant is necessary when the drying time or dew point cannot be maintained or when the pressure drop increases to an unacceptable level.

As a desiccant, Noble Activated Alumina is capable of removing significant amount of water from liquids and essentially all water from gases and air. As an absorbent, activated alumina can perform variety of services such as removing oil vapors from compressed gases, removing acids from lubricating oil or refrigerants, removing fluorides from water etc. 

Noble Activated Alumina balls are capable of drying gases to dew point below -65o C when used with high regeneration temperatures and dry gas regeneration. In usual practice, temperature between 160 to 250oC can be required.

Noble Activated Alumina Spheres, standard size is 3 mm to 5 mm & 6 mm to 8 mm.
