Principles of oil removal by activated carbon filters
Thread Content
An activated carbon filter removes oil contaminants by taking advantage of the strong adsorption properties of activated carbon. It is equipped with a sufficient amount of specialized activated carbon adsorbent in a tank-like structure, and the internal piping layout is optimized to ensure uniform airflow through the filler bed inside the tank, thereby ensuring its oil-removal efficiency. Activated carbon is a non-polar adsorbent with strong adsorption capacity, and its specific surface area generally ranges from 600 to 2000 m²/g. Oils in compressed air (organic compounds with C6+ structure) have weak polarity, and activated carbon possesses a strong adsorption capacity to remove them. It can not only remove liquid oil and suspended oil from compressed air, but also effectively adsorb and remove oil vapors; as a result, the oil content in the treated compressed air can be ensured to reach level 0. It can also be used to remove odors from gases.
Waste activated carbon can be reprocessed and recycled by oneself, or it can directly become solid waste, but it needs to be collected at designated locations.
