Chemical Process Control: Modeling a Simple Blend Tank

Understanding how chemical processes respond to changes is critical for maintaining safety, quality, and efficiency in industrial plants. This course introduces you to the core principles of process dynamics and control using the classic blend tank as a foundational model. You will learn how to translate physical systems into mathematical equations and predict how they behave under real-world conditions. Starting with fundamental terminology and conservation laws, the course guides you step-by-step through modeling, steady-state analysis, and transient responses. What you will learn: Understand the core principles of process dynamics and chemical control systems; Build mathematical models of a simple continuous holding tank using mass balances; Analyze the response of a system to steady input and identify equilibrium states; Evaluate how a system reacts to sudden step disturbances and load changes; Apply transfer functions and basic differential equations to predict process behavior; Explore modern digital control concepts and simulation workflows used in the industry today. You will begin with basic concepts of process variables, inputs, and outputs before moving on to hands-on modeling scenarios and disturbance analysis. This course is designed for engineering students, junior process engineers, and plant operators who want a solid foundation in process control without any prior advanced modeling experience.
