Module summary

This 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.

Learning outcomes
Chemical Engineering Principles
- Have a knowledge and understanding of basic mathematical models and allied engineering principles relevant to chemical engineering.
- Understand the principles of material and energy balances and be able to apply them to chemical engineering problems.
- Understand the principles of momentum, heat transfer and application to problems involving fluids.
- Understand the thermodynamic and transport properties of fluids and multiphase systems.
- Be familiar with the application and limitations of a range of modelling approaches including first-principles models and simple empirical correlations.
- Be competent in the use of numerical and computer methods, including commercial software for solving chemical engineering problems.
- Be able to apply digital techniques to solving chemical engineering problems.

Chemical Engineering Design
- Understand that design is an open-ended process, lacking a pre-determined solution, which requires: synthesis, innovation and creativity; choices on the basis of incomplete and contradictory information; decision making; justification of the choices and decisions taken.
- Be able to find and apply, with judgement, information from technical literature and other sources.
- Understand the importance of identifying the objectives and context of the design in terms of: the technical requirements.
- Be able to synthesize a conceptual multi-step process and apply analysis techniques to it.
- Be able to deploy chemical engineering knowledge using rigorous calculation and results analysis to develop a design and with appropriate checks on feasibility and practicality.
- Understand the principles on which processing equipment operates to determine equipment size and performance of common items such as heat exchangers.
- Be able to work in a team and understand and manage the processes of: peer challenge; planning, prioritising and organising team activity; the discipline of mutual dependency.
- Be able to communicate effectively to: acquire input information; present the outcomes of the design clearly, concisely and with the appropriate amount of detail, including flowsheets and stream data; explain and defend chosen design options and decisions taken.

Skills outcomes
On completion of this module, students should have the following skills:
- Pipeline design 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 process modelling software to solve mass and energy balances.

Syllabus

Mass Balance
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 Balance
Energy Balances for Reacting Systems: Reference states, heats of reaction, formation and combustion, solution and mixing, 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 Mechanics
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, pipe friction factor and pressure drop. Boundary Layer Flow: Laminar/turbulent boundary layers in flow over a flat surface, boundary layer thickness, velocity distribution and shear stress. Compressible Flow: Basic characteristics, equations for isothermal/adiabatic flows in pipe.

Heat Transfer
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.

Group Project
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 quantitative elements such as process safety and mass balances.

Private study

Students 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 Feedback

Students' 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.
