Summary
Section A: This section is made up of eight topics, which are detailed below. Each topic covers a fundamental principle in reactor design, also how students can combine those principles to derive/optimise the reactor design equations. The textbook Fogler, H. Scott "Elements of chemical reaction engineering", 4th ed., Prentice Hall, 2005 is closely followed. The main topics are:
• Mole Balances
• Conversion and Reactor Sizing
• Rate Laws and Stoichiometry
• Collection and Analysis of Rate Data
• Isothermal Reactor Design
• Multiple Reactions
• Steady-State Non-isothermal Reactor Design
• Catalysis and Catalytic Reactors
Section B: This section provides an appreciation of the dynamic behaviour of processes, effects of disturbances and single loop controllers, the features and constraints on choice of conventional process control instruments and equipment and a basis for process analysis and design using dynamic process models and dynamic simulation. The main topics are:
• Process Dynamic Characteristics: 1st order, 2nd order and dead time
• Feedback Control Methods
• Controller Tuning
• Cascade & Feedforward Control
• Design Philosophy & Flow-sheeting
• Frequency Response
The course consists of lectures, which will include problem solving and interactive computer modules (ICM). Problems are to be worked primarily at home by the students.

Educational Aims
To demonstrate how to apply the fundamental principles of chemical kinetics along with heat and mass transport to design chemical reactors for both homogeneous and heterogeneous reactions. To provide a basis for understanding the dynamic behaviour of a process system and the options available for its safe single loop control.Learning Outcomes
A2 Chemical Engineering Principles:
A2.1.2 Be proficient in applying these principles to problems involving fluid flow, heat transfer, mass transfer and reaction engineering. To understand the influence of hydrodynamic, heat and mass transfer and kinetics on the design of reactors.
A2.1.3 Be able to apply the principles to the analysis of complex systems within a structured approach to safety, health and sustainability. It is desirable that throughout the programme the students should gain an understanding of the broad range of applications of the principles and develop the ability to analyse, model quantitatively and synthesise at the appropriate scale. Assessment: Through reactor design coursework and the Modern control engineering coursework, using the real world case studies.
A2.1.4 Different types of process, including continuous and batch chemical processes and bioprocesses.
Consider different types of processes, advantages and limitations and scope of applications for each type of reactor.
A2.1.5 Different time scales: short and long periods steady and unsteady state
A2.2.5 Understand the principles of chemical reaction and reactor engineering.
Apply basic concepts of reactor engineering to concrete cases of increasing complexity. Assessment: Through reactor design coursework using the real-world case study.
A2.3.3 Be able to select and adapt computational and analytical techniques to tackle complex problems. Assessment: Through the Modern control engineering coursework, using the real-world case study.
A2.5.1 Understand the principles of batch and continuous operation and criteria for process selection. Assessment: Through reactor design coursework using the real-world case study.
A2.5.3 Understand system dynamics, being able to determine the dynamic response to changes in a process, design measurement and control functions, and determine its performance. Assessment: ROGO test
A2.5.4 Be able to apply digital techniques to solving chemical engineering problems. Assessment: Through the Modern control engineering coursework, using the real-world case study.
A2.6.5 Be aware of specialist aspects of safety and environmental issues, such as noise, hazardous area classification, relief and blowdown, fault tree analysis. Assessment: Students become aware of the hazards and able to implement safety measures such relief valves etc. This is assessed through reactor design coursework and the Modern control engineering coursework, using the real-world case studies.
A4 Chemical Engineering Design:
A4.2.11.1 Detail design of control systems based on process dynamics
Assessment: This is achieved via workshop where Simulink is used to study the process dynamics and calculate the tuning parameters of a PID controller and assessed via a ROGO test.
