✦ Synopsis
Specific interfacial areas for cocurrent gas-liquid flow through a vertical tube 6 mm i.d. and 1524 mm long have been obtained by absorbing carbon dioxide from air into aqueous sodium hydroxide. The interfacial area was found to increase with the liquid flow rate but a maximum was observed on the interfacial area vs gas flow rate curves. The position of the maximum is virtually independent of the liquid flow rate. A correlation is presented in terms of the rate of creation of the interfacial area V,,a& against the pressure drop.

A model is proposed for cocurrent gas liquid flow through a packed bed. For a given packing, gas and liquid flow rates, we proposed that (i) liquid holdup is a function only of pressure gradient and liquid flow rate and (ii) pressure gradient is only a function of liquid holdup and gas flow rate. Eq
