Optimizing Solid Dissolution Through Better Mixing Design
Introduction • Dissolution is a critical operation in many pharmaceutical, chemical, food, and specialty chemical manufacturing processes. The rate at which solid particles dissolve directly influences batch cycle time, product quality, process consistency, and overall manufacturing efficiency. • Although increasing agitator speed is often considered the simplest solution for improving dissolution, the process is governed […]
Continuous Flow Process: Impact of Feed Position in a Multistage Impeller Reactor on Reaction Performance
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 […]
Optimizing Liquid–Liquid Mixing Scale-Up for Consistent Drop Size and Mass Transfer Using VisiMix
Introduction • Liquid–liquid mixing is a key operation in processes such as extraction, emulsification, and multiphase reactions, where performance is strongly influenced by droplet size distribution and interfacial area. In such systems, two competing phenomena—droplet break-up and coalescence—occur simultaneously, and their balance determines the overall mass transfer efficiency and process outcome. • While achieving the […]
Gas–Liquid Mixing: Why Higher RPM Is Not Always Better
Introduction • Gas–liquid mixing plays a critical role in determining reaction performance, mass transfer efficiency, and product quality in a wide range of chemical and biochemical processes. Efficient gas dispersion ensures adequate interfacial area for mass transfer, directly influencing reaction rates, conversion levels, and overall process reliability. • In industrial practice, it is often assumed […]
Integrated Reaction Kinetics and Mixing Simulation of a Complex Five-Step Enzymatic Reaction Using VisiMix Chem
Introduction Complex enzymatic reactions in continuous reactors involve intricate interactions between reactants, enzyme activity, intermediate complex formation, and competitive side reactions. The performance of such systems depends on the dynamic evolution of concentration fields, reaction pathways, and hydrodynamic conditions throughout the reactor volume.Accurate prediction of these phenomena requires an integrated approach that captures both the […]
Scaling-Up Emulsification Using Multi- Stage In-Line Rotor–Stator Devices
Emulsification is a critical unit operation in many chemical, pharmaceutical, and specialty manufacturing processes, where product performance and stability are strongly influenced by droplet size distribution. While pilot- scale trials can demonstrate technical feasibility, scaling up to higher throughputs often introduces challenges such as increased droplet coalescence, non-uniform energy dissipation, and loss of product consistency.
