The mass transfer characterization of a novel design rotating liquid redistributor is presented, where the redistributor has three concentric, perforated rings which act as liquid redistribution rings. Oxygen stripping from water is used to obtain values for the overall mass transfer coefficient of the redistributor. It was found that the main contribution to the overall mass transfer is the impingement of droplets on the redistribution rings, while the mass transfer of suspended droplets in the gas phase was almost negligible. Furthermore, it was shown that the experimentally determined contribution to mass transfer of the droplet impingement correlated strongly to the mean momentum flux of the droplets. Lastly, the energy dissipation rate was compared to a rotating zig-zag bed, where at lower liquid flow rates and rotational speed the energy dissipation rate in the redistributor was lower, while at higher liquid flow rates and rotational speeds it was lower in the rotating zig-zag bed.

提出了一种新颖设计的旋转液体再分配器的传质特性，其中再分配器具有三个同心的穿孔环，它们充当液体再分配环。从水中脱氧可用于获得再分配器总传质系数的值。已发现，对总体传质的主要贡献是液滴在再分配环上的撞击，而气相中悬浮液滴的传质几乎可以忽略。此外，已经表明，实验确定的对液滴撞击的传质的贡献与液滴的平均动量通量强烈相关。最后，将能量耗散率与旋转之字形床进行比较，
