The residence time distribution was used to study the hydrodynamic behaviour using the pulse input tracer technique. The effect of medium, compartment-wise variation in the mixing patterns inside the reactor and hydraulic retention time on the hydrodynamic characteristics of the reactor was studied. The influence of the number of compartments was predominant compared to the hydraulic retention time and presence of a medium. The flow regime in the first, second and third compartments was in the intermediate state whereas the flow regime was in plug-flow state in the rear compartment. The interactive effects were evaluated using response surface methodology

Abstract


The residence time distribution was used to study the hydrodynamic behaviour using the pulse input tracer technique. The effect of medium, compartment-wise variation in the mixing patterns inside the reactor and hydraulic retention time on the hydrodynamic characteristics of the reactor was studied. The influence of the number of compartments was predominant compared to the hydraulic retention time and presence of a medium. The flow regime in the first, second and third compartments was in the intermediate state whereas the flow regime was in plug-flow state in the rear compartment. The interactive effects were evaluated using response surface methodology
