Note on a method of fitting a two-parameter distributed model to an experimental residence time distribution: Application to gas flow in gas-Liquid packed column

Abstract A convenient method is presented for the determination of the parameters of a model in which a fluid in piston flow continuously exchanges mass with stagnant fluid. The technique is applied to the gas phase in counter-current flow in a trickle flow irrigated packed tower. The validity of the model is confirmed and its predictive accuracy is compared with the axially dispersed plug flow model by convolution using the calculated parameters.
