To introduce students to important aspects of safety, process control, and process modelling in chemical and biochemical processing systems.

Health and safety at work: types of factory environment and their physiological and psychological risks. Current legislation in the area of employer and employee liability. Codes of practice. The role of management and unions in safety. · Overview of Health & Safety legislation; · Overview of Accident Causation; · Overview of chemicals in the workplace: - Hazardous properties of chemicals; - Managing chemicals in the workplace; - Hazard classifications. - CPL / CLP requirements; - Chemical Agent Regulations - Code of Practice; - Hierarchy of Control; · Safety Data Sheets (SDSs); · Overview of useful websites: 'COSSH Essentials', TOXNET, Sigma-Aldrich, etc. Introduction to process control: basic control modes e.g. P, PI, PID; control system architecture and dynamic behaviour for SISO processes; controller tuning; control system hierarchies for chemical/biochemical processing plants. Equipment and instrumentation used in chemical and biochemical processing operations: sensing and measurement; signal transmission; controllers; final control elements. Simulation exercises to learn about the process control principles by studying the control system behaviour as a reaction to set point changes. Process modelling; application of material and energy balances in the formulation of quantitative process models; process characteristics and dynamic response behaviour of first and second order systems.

On successful completion of this module students should be able to: • Recall physical representations and block diagrams for feedback, feedforward and inferential control configurations for simple processes. • Show a basic knowledge of the principles of operation and characteristics of common process control hardware and instrumentation. • Define the operating characteristics of ON/OFF, P, PI, PD, and PID control modes. • Use quantitative models to describe the dynamic response of first order processes. • Describe the characteristics of second and higher order processes. • Tune simple control systems using both open and closed loop methods. • Model simple process control systems using process dynamic modelling software. • Show the time-domain functions describing of the output signal when there are set point and disturbance changes when working with Laplace transfer functions and show the different types of responses. • Describe the processes involved in the execution of a risk assessment • Recognise the basic principles of accident prevention • Show an understanding of the principles of Occupational Health and Safety in industrial processes

On successful completion of this module students should be able to: • Display a professional commitment to ensuring health and safety at work. • Value the use of mathematical models to describe the dynamics of processes and their control systems. • Acknowledge the assumptions and limitations of mathematical models of processes.

On successful completion of this module students should be able to: • Operate sample process equipment to characterise its dynamics. • Operate control systems for sample process equipment.

This module is taught via a combination of lectures and laboratory experiments. Through the experiments, students will apply the theory from the lectures to characterise the dynamics of a process, design a control system for it, and test the operation of their control system. Contemporary research literature on process modelling and control is integrated in the lectures and laboratory experiments.
