摘要：

A Higee absorption process was developed to remove VOCs (volatile organic compounds) from air into an aqueous phase under a centrifugal field. The experimental results showed that the overall volumetric gas-phase mass-transfer coefficient (K(G)a) increased as a function of the gas Grashof number (Gr(G)) to the power of 0.18. In analyzing k(G) and a individually, it was found that the enhancement of mass transfer by the centrifugal force can mainly be attributed to an increase in the effective gas-liquid interfacial area. The values of k(G) lie in a range similar to that for conventional packed beds.
