The high development of industries leads to significantamountof waste hydrophobic volatile organic compounds (VOCs), and thesehave caused serious environmental concerns. Because of the physicalproperties of the hydrophobic VOCs, a hydrophobic absorbent is neededin order to make the process more efficient if absorption is considered.However, most of these absorbents have high viscosities which leadsto a low mass transfer coefficient. Thus, a cross-flow rotating packedbed (RPB) was evaluated for the feasibility of absorbing the hydrophobicVOCs, xylene, and toluene, by silicon oil, a model hydrophobic absorbent.The result shows that the absorption percentage could be up to 98%within a second contact of liquid and gas.
