Abstract

Polytetrafluoroethylene (PTFE) material, which is well-known for its excellent anticorrosion properties, was used as wire mesh packing in a rotating packed bed (RPB). The effective interfacial area (a_e) and the volumetric liquid-side mass-Transfer coefficient (k_La_e) of the RPB with PTFE packing was studied experimentally by a NaOH-CO2 chemical absorption system and an oxygen-water physical desorption system, respectively. Experimental results showed that both a_e and k_La_e increased with decreasing fiber diameter and pore size. As for material, mass-Transfer performance of the PTFE packing was lower than that of the stainless steel wire mesh packing but is applicable in some high-corrosion and -viscosity environments. Moreover, correlations for a_e and k_La_e were proposed.
