CHEN10010 Chemical Engineering Process Principles

Academic Year 2022/2023

This module will introduce students to principles and techniques used in the analysis of
chemical and biochemical engineering processes. Steady-state and unsteady-state mass
(material) balances and energy balances are fundamental tools for the assessment of such processes.
The use of balances in, for example, the development of sustainable processes will be
introduced. Students‘ analytical abilities and problem solving skills will be developed through
in-class exercises and homework assignments. Key concepts in process safety will be
introduced.

Topics:
- Introduction to Chemical Engineering Process Principles
- Units, Dimensional Consistency, Dimensional Analysis, Mass & Mole Fractions
- Engineering Calculations: Linear Interpolation, Linear Regression, Data-Fitting, Linear & Logarithmic Scales
- Mass Balances for Single Processes
- Multiple Unit Processes – Non-Reacting Systems
- Systems With Single Chemical Reactions
- Material Balances for Combustion Processes
- Transient Mass Balances for Non-Reacting Systems
- Ideal/Non-Ideal Gases - van der Waals equation
- Use of the Thermodynamic (Steam) Tables
- Energy Balances – First Law
- Energy Balances – Open Steady-State Systems
- Use of Mass & Energy Balances to establish “green metrics” for process evaluation and to develop sustainable processes.

Learning Outcomes:

On completion of this module students should be able to:
1. Convert a process description into a clearly labelled process flow diagram and to conduct steady state mass and energy balances leading to a fully balanced process flow diagram for both single and multiple process units involving non-reactive and reactive systems.
2. Apply mass and energy balance concepts to simple, batch, fed batch and continuous processes.
3. Describe selected equations of state for ideal and real gases and to be familiar with the concept of the law of corresponding states.
4. Apply linear interpolation, linear regression and basis data-fitting techniques in the use and/or analysis of quantitative information.
5. Recognise the importance of the concepts of Safety, Health and the Environment and Sustainability in the Chemical Engineering context.
