Introduction to Multiphase Chemical Reacting Systems

In chemical engineering, designing efficient reactors requires a deep understanding of how physical transport processes interact with chemical kinetics. This written course provides a clear, step-by-step introduction to analyzing systems where gas and liquid phases react under the influence of mass-transfer limitations. You will learn how to identify, model, and manage these physical resistances to optimize chemical processes. By completing this course, you will transition from understanding simple homogeneous reactions to confidently analyzing complex multiphase systems where diffusion and reaction occur simultaneously. What you'll learn: - Understand the foundational concepts of mass transfer and chemical kinetics in multiphase environments. - Analyze gas-liquid reactions and identify when external mass-transfer resistance limits the overall reaction rate. - Evaluate the role of the Hatta number and enhancement factors in characterizing reaction regimes. - Apply mathematical models to describe concentration profiles across phase boundaries. - Practice calculating overall reaction rates in the presence of mass-transfer limitations. This course begins with a thorough introduction to essential terminology, phase equilibria, and transport phenomena before moving into practical mathematical models and engineering calculations. You will read comprehensive explanations and study detailed, step-by-step derivations that connect physical chemistry with practical reactor analysis. This course is designed for undergraduate engineering students, chemistry professionals, and beginning chemical engineers who want to build a solid foundation in multiphase reaction engineering. No advanced background in transport phenomena is required to start. Begin reading today to master the core principles of multiphase reaction engineering.
