CEIC3000 Process Modelling and Analysis Week 1 Session 1, 2012 A/Prof. Jie Bao * 1 About the subject 1.1 What are process models This subject is about process modelling, analysis and optimisation. The ever increasing global demand for better utilisation of raw material and energy resources in an environmentally-sustainable manner means that greater ingenuity must be employed in the development of new processes (or improvement of existing ones). Thus, the traditional but time-consuming and expensive practice of first building a small- scale replica of the process for the sole purpose of investigating its dynamic and steady-state behaviour to acquire optimal operating conditions is a luxury that can no longer be afforded. Consequently, a more quantitative approach to process design and operation is now more attractive to the industry. Process modelling, analysis and optimisation deals with the principles and methods for effectively carrying out this exercise and as a result, this course is a central component of the chemical and process engineering curriculum. Specifically, the objectives of the course are to: Provide you with key mathematical methods useful for the analysis of wide-ranging chemical engineering problems. Acquaint you with the different techniques to mathematical model building, for example, phe- nomenological and empirical approaches. Integrate results from modelling exercise with known physicochemical features of the system to evolve better process design ad operation. Indeed, this course allows you to refine and couch your knowledge of other core subjects in a more analytical fashion therefore making it possible to consolidate your understanding and even draw extensions to other disciplines. In the first part of this subject, we will study process modelling. That is to describe a dynamic process using mathematical equations. We will also learn some basic analysis methods to analyse process models in the context of systems theory. Before proceeding, let us look at the definition of models. The Webster dictionary defines the term “model” as: A small representation of a planned or existing object. From McGraw Hill Dictionary of Scientific and Technical Terms, we can find the following definition: “ A mathematical or physical system, obeying certain specified conditions, whose behaviour is used to understand a physical, biological or social system to which it is analogous in some way ”. In this class, we refer to a mathematical model: * Last modified Tuesday, February 28, 2012 14:59 1

A process model is a set of equations (including the necessary input data to solve the equations) that allows us to predict the behaviour of chemical process system. While you have been developing mathematical equations to describe chemical processes since Year
