Activated alumina balls for oil purification are an effective way to remove water and contaminants from the oil. The desiccants are highly porous and absorbent, making them ideal for oil purification.
The porous and absorbent nature of the activated alumina balls makes them ideal for oil purification. The porosity of the balls allows oil to pass through and be filtered. As the oil passes through the balls, the water molecules and contaminants are absorbed, leaving behind clean oil. The absorbency of the balls ensures that moisture and contaminants are not released back into the oil.
When using activated alumina balls for oil purification, it is important to ensure that the desiccant is of the highest quality, because poor quality may not be as effective in removing moisture and may even release contaminants back into the oil. Therefore, it is important to choose a suitable desiccant-activated alumina for oil purification.
Oil should be filtered with the activated alumina balls in a way that ensures that the oil flows through them in a continuous flow. This will ensure that all the contaminants and moisture are absorbed by the desiccant.
It is also important to ensure that the flow rate of the oil is not too high. Too high a flow rate will cause the balls to be pushed out of the filter and reduce their effectiveness. The ideal flow rate should be such that the oil passes through the balls at a slow and steady pace.
Thus, once the purification process is complete, the activated alumina balls should be replaced. This is to ensure that the balls remain effective and to prevent any contaminants from being released back into the oil. The balls should also be inspected regularly for any signs of damage or wear.
In conclusion, activated alumina has been used for the reconditioning of oils used in the turbine, transformer, and circuit breaker. Being resistant to shocks and abrasion, the desiccant is known to be highly effective for oil purification. Oils change their characteristics with time. Acid is one of the by-products that oils generate as they deteriorate/oxidize after being in contact with moisture, air, heat, gases, etc. This if left unchecked can raise the total acid numbers causing serious damage to the mechanical parts.
To avoid this, activated alumina balls are for oil purification or for the removal of acids from oil.
