✦ Synopsis

Shorter Commumcafions chemical reactron, however, the absorbed gas reacts upon dlssolvrng m the hqmd, and the dnvmg force wdl be considerable also m the semi-stagnant zones, which will contnbute conslderably to the overall mass transfer rate The interfacIal area was measured m three of the tested packmgs, usmg the chemical method[8,9] This method LS based on the fact that m the case of a rapld first-order reaction, the mass transfer rate becomes controlled by the chemical reactlon, mdependently of the turbulence m the hquld In this case the mterfaclal area can be obtamed from data of the total absorption rate, the specltic reaction rate k and the dtiuslon coefficient of the gas m the bquld. Da8 The pseudo-first order reactlon between carbon dtoxlde and sodium hydroxide was used A solution of NaOH 0 5 N was used as the hquld m the expenmental setup described before, the absorbmg gas bemg a mixture of lo-20% CO2 m m With this hqu:d and gas mltlal concentrations, the condltton for pseudofirst order rea&on m the hquld[9] ED d/(kBQ) e 1+ zA*
