在这项工作中，气侧传质进行了研究，在旋转填料床（RPB）与结构化泡沫镍填料，具有不同的表面性质，无论是未改性的泡沫镍填料（NNP）或疏水表面改性泡沫镍填料（SNP）。实验研究了转速、液气流量对NNP和SNP旋转床气侧体积传质系数kGae的影响。结果表明，负载SNP的RPB比负载NNP的RPB具有更高的传质效率。在实验数据的基础上，提出了泡沫镍规整填料旋转床中的k Ga关联式，为泡沫镍规整填料旋转床的设计提供了快速计算传质系数的方法。
In this work, the gas-side mass transfer was investigated in a rotating packed bed (RPB) with structured nickel foam packings, with different surface properties, either a nonmodified nickel foam packing (NNP) or a hydrophobic surface-modified nickel foam packing (SNP). Effects on gas-side volumetric mass-transfer coefficient (kGae) of rotational speed, liquid flow rate, and gas flow rate were experimentally studied in the RPB with NNP and SNP. It can be found that the RPB loaded with SNP has a higher mass-transfer efficiency, compared with that loaded with NNP. Based on the experimental data, correlation ofkGaein a RPB with structured nickel foam packing was proposed, which can hence provide a fast calculation of mass-transfer coefficients for the RPB design with structured nickel foam packing.
