Introduction
• Continuous flow reactors are widely used in the chemical and pharmaceutical industries due to their ability to provide
consistent product quality, improved process control, and enhanced safety. In such systems, reactor performance is
strongly influenced not only by reaction kinetics but also by hydrodynamic factors such as mixing efficiency, flow
patterns, and feed inlet location.
• Multistage impeller configurations are commonly employed to improve axial circulation and reduce concentration
gradients in tall reactors. However, the effectiveness of these systems depends significantly on how and where
reactants are introduced into the vessel. Feed position can influence local reactant concentrations, mixing intensity,
residence time distribution, and ultimately the balance between desired product formation and undesired by-product
formation.
• This study uses VisiMix Chem to evaluate the influence of feed position in a continuous reactor equipped with a
three-stage paddle agitator. By comparing different feed inlet locations while maintaining identical operating
conditions, the study provides insight into the relationship between mixing dynamics, reactant conversion, product
formation, and by-product generation.
