This unit of study has two strands: the first covers process modelling and process control while the second is concerned with reaction engineering. All industrial processes require some process monitoring and control for satisfactory operation. The first strand commences with process data management before moving on to empirical modelling. The first strand will concentrate on the role of process control covering: the development of linear models, control system analysis, the design and performance of feedback control systems, and the use of control related software. This unit demonstrates that: process control is an integral concept for any modern plant; a unified approach allows a diversity of application fields to be readily handled via a consistent approach from data analysis, though process control to process optimisation. The second strand of this unit of study focuses on the understanding of the key concepts of reaction engineering in process design. It covers reaction kinetics, stoichiometry, reactor design, multiple reaction systems, catalysis and using reaction data to estimate rate laws. The unit will allow each student to achieve and demonstrate competency through a range of individual and group-based activities. By the end of this unit a student should achieve competence in the following: process data management skills relevant to engineering (data-based modelling and data reconciliation techniques); appreciation of the role of process control in modern manufacturing; designing an appropriate feedback control system and analysing its performance for a range of process applications using both traditional and software-based techniques; appreciation of the limitations of feedback control and be able to design a range of common enhancements; appreciate the limitations that exist whenever mathematical models are used as the basis for process control; appreciate the 'vertical integration' that exists from modelling, through control, to optimisation. This unit is part of an integrated third-year program in chemical engineering. Completion of this body of work is required before a student will be permitted to move into the final-year with its emphasis on detailed design work, thesis based research and advanced engineering options.
