Gas-liquid mass transfer of aqueous Taylor flow in monoliths

The gas-liquid mass transfer of a monolith operating in the Taylor flow reg ime is presented. Mass transfer measurements are compared with a literature model derived for single capillaries. The comparison resulted in a predict ion of the unit cell length (gas bubble + liquid slug). Independent measure ments of the liquid slug length showed that the predicted unit cell length is close to the measured ones. This leads to the conclusion that mass trans fer models for single capillaries may indeed be used for monoliths. Additio nally, it is shown that the liquid slug length may also be estimated from p ressure drop measurements. (C) 2001 Elsevier Science B.V. All rights reserv ed.
