Module Overview

The conservation of mass and energy are fundamentals on which chemical processes are based and being able to formulate and solve material and energy balances is an essential skill of an engineer.  This module covers the fundamental concepts used when analysing the mass and energy flows in chemical processes.

 

 

Prerequisites/Co-requisites

The normal entry requirements for Level 1 of the Chemical & Bio-systems Engineering and the Chemical Engineering programmes.

Module Aims

To provide students with:

 

·       a systematic understanding of the principles used to establish material and energy balances for chemical processes

 

·       a comprehensive understanding of the units and physical quantities necessary to properly define material and energy balances

 

·an opportunity to extensively practice the principles and techniques of solving material and energy balances in a supportive environment.

 

 

Learning Outcomes

Upon successful completion of the module you will be able to :-
·         understand the foundations of different unitary systems and fluently convert quantities between them
·         explain the Ideal Gas Laws and confidently analyse the P-V-T-mass relationships of Ideal Gas mixtures
·         use with confidence saturated vapour pressure data and Raoult’s Law and so analyse the saturation process of a gas mixture
·         confidently apply sensible heat, the energy associated with a phase change and reaction enthalpy changes to the analysis of multi-phase reacting systems  
·         understand and be able to apply Gibbs Phase Rule
·         comprehensively understand and be critically aware that mass and energy are conserved
·         confidently formulate a solution to and then solve well posed material balance problems which may involve any combination of the following: reactions, multiple phases, multiple series or parallel process units, recycle/bypass/purge using data expressed in a mixed set of units
