Module summaryThis module includes the following core chemical engineering topics: Mass and Energy Balances, Fluid Mechanics and Heat Transfer. It builds on these topics covered at an introductory level in Engineering Science 1 in Level 1.
Objectives- To develop a deep understanding of the concepts and methodology for performing mass and energy balance calculations for processes with chemical reactions and combustion.
- To develop a deep understanding of advanced principles of fluid mechanics and heat transfer.
- To provide a basis for the Level 3 Design Project module.
On completion of this module, students should have a deep knowledge of:
- Principles for mass and energy balances and be able to apply these to write and solve mass/energy balances for processes with chemical reactions and combustion.
- Laminar flows in confined geometries (e.g. pipes, parallel plates) and with free-surface (e.g. liquid films over inclined/vertical plates).
- Main characteristics of turbulent and compressible flows in pipes.
- Pressure drop calculations in pipeline systems.
- Methodologies for pipeline and heat exchanger design.
On completion of this module, students should have the following skills:
- Pipeline design and pump calculations.
- Heat exchangers design calculations.
- Calculations of mass and energy balances with and without chemical reactions for individual process equipment and for a process plant.
- Use of spreadsheets and HYSYS to solve mass and energy balances.
Reactive Systems: Principles of stoichiometry, limiting and excess reactants, conversion, selectivity and process yield. Mass Balances for Reactive Systems: Mass balances on molecular and atomic species, independent equations, independent species, independent reactions, extent of reaction, mass balances for systems with recycle, bypass and purge streams, mass balances for combustion processes - calculation of the product composition from the combustion of hydrocarbon fuels. Mass balances for transient processes.
Energy Balances for Reacting Systems: Reference states, heats of reaction, formation and combustion, energy balances on isothermal and adiabatic chemical reactors. Calculation of flame temperatures. Energy balances for combustion equipment. Energy balances for transient processes. Simultaneous mass and energy balances.
Fluid Motion: Classification of fluid flows and basic flow characteristics, review of the continuity, energy and momentum equations derived in Engineering Science 1. Laminar Flow: Flow in pipes and Hagen-Poiseuille equation, flow through ducts, flow between parallel plates and over inclined/vertical plate. Turbulent Flow: Fluctuating and mean velocity, Reynolds stresses and eddy viscosity, power-law velocity profiles, log-law of the wall. Boundary Layer Flow: Laminar/turbulent boundary layers in flow over a solid surface, boundary layer thickness, velocity distribution and shear stress. Compressible Flow: Basic characteristics, equations for isothermal/adiabatic flows in pipe.
Introduction: Review of modes of heat transfer. Convective Heat Transfer: Forced convection, heat transfer in the entrance and fully developed regions of pipes, heat transfer with phase change - boiling and condensation, natural convection. Heat Exchanger Design: Classification of heat exchangers, mechanical construction, shell-and-tube heat exchanger design using LMTD and effectiveness-NTU methods, evaporative heat exchangers. Radiation: view factors.
The project will require selection of a process route to the required product specification for a specified output and location. Selection of the type of equipment and control measures to ensure the product specification is achieved will be included. A group report will be produced listing the options justifying those selected. This will include qualitative and quantitave elements such as process safety and mass balances.

Private studyStudents are expected to read the recommended textbooks together with the lecture handouts for developing a deeper understanding of the topics covered in the formal classes. They should look at the worked out example problems in textbooks and in handouts to learn how theory can be applied to solve numerical problems. To develop problem solving skills they should independently try to solve the numerical problems given in the Problem Sheets provided by the lecturers and also textbook exercise problems prior to the tutorial class. As part of a group (18 hours) and independent learning, students are expected to carry out calculations for the Group Project.
Opportunities for Formative FeedbackStudents' progress will be monitored via:
- The extent of participation and response to questions asked in the formal lecture and tutorial classes.
- Feedback from formative class tests.
