Use as a desiccant, it works by a process called adsorption. The water in the air actually sticks to the
alumina itself in between the tiny passages, as the air passes through them. The water molecules
become trapped so that the air is dried out as it passes through the filter. This process is reversible,
and if the alumina desiccant is heated to about 200°C it will release all of the water stored in it. This
process is called regenerating the desiccant. Air always has some water in it; one way to measure
the amount of water in the air is the air's dew point.
Application
It can be used as desiccant and purificant in fertilizer or petrochemical industry. And also be used for
the gas drying in oxygen making, textile industry and electronics.
