Gas–Liquid EffectiveInterfacial Area in a Rotating Packed Bed.

Stainless steel wire mesh packing is widely used forexperimental and industrial applications in rotating packed beds (RPBs)for gas–liquid contacting because it has a higher mass-transferperformance than other conventional packings. In this work, the gas–liquideffective interfacial area of a conventional RPB was studied witheight types of stainless steel wire mesh packings, consisting of fourdifferent stainless steel fibers. Gas–liquid chemisorptionwith CO2in NaOH solution was employed to measure the effectiveinterfacial area for all types of packings with different rotationalspeeds and gas–liquid ratios. An empirical correlation thattakes the effects of the fiber diameter and opening size of the wiremesh into consideration was proposed for the calculation of the gas–liquideffective interfacial area of stainless steel wire mesh packings ina conventional RPB.
