Introduction to Plug Flow Reactors in Chemical Engineering

Understanding how chemical reactions behave in continuous systems is a cornerstone of industrial chemical engineering. This course provides a clear, accessible introduction to the Plug Flow Reactor (PFR), one of the most essential reactor models used in the industry today. You will learn how to transition from basic reaction kinetics to modeling continuous-flow systems with confidence. Through structured written lessons, you will master the foundational mathematics and engineering principles that govern these reactors, preparing you to solve real-world process design challenges. We start with fundamental definitions and key terminology before moving into practical design equations and modern simulation concepts. What you'll learn: - Understand the core concepts, assumptions, and physical characteristics of plug flow reactors - Derive and apply the fundamental PFR performance and design equations - Calculate reactant conversion, concentration profiles, and space time for various reaction orders - Analyze temperature effects and energy balances within plug flow systems - Compare PFR performance with Batch and Continuous Stirred-Tank Reactors (CSTR) - Explore modern computational approaches to reactor modeling and basic simulation workflows This course begins with essential terminology and the physical behavior of fluids in a pipe, builds up to the mathematical derivation of the design equation, and concludes with practical sizing and optimization scenarios. It is designed specifically for beginners, engineering students, and practicing professionals looking for a solid refresher, with no advanced prerequisites required.
