Gas-Side Mass Transfer in a Rotating Packed Bed with Structured Nickel Foam Packing

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 (k(G)a(e)) 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 of kGae in 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.
