Summary
The module is designed to cover material balances including once-through and recycle systems; flowsheets for continuous processes; batch processes; steady and unsteady state operation; reacting and non-reacting systems; energy balances; combustion calculations; heat balances in chemical and physical systems; enthalpy/composition diagrams. In addition the module covers the principals of physical separation processes namely basic separation principles, single and multiple effect evaporation, vapour recompression integrated with evaporator, crystallization separation processes, cascade and counter-current leaching process, stagewise and continuous liquid-liquid extraction process. Principles of operation, design concepts and sizing of process equipment are included.
Re-Assessment: The module will be re-assessed through 100% individual examination which will be centrally timetabled exam in the University's resit period.
Target Students
Students registered in the Department of Chemical and Environmental Engineering only.
Assessment
- 40% Practical: Practical assessment week
- 60% Exam 1 (2-hour): Exam end of autumn semester
Assessed by end of designated period
Educational Aims
To provide an understanding of the fundamental material and energy balances that underpins process engineering. To provide knowledge and understanding of the methods of calculating material and energy balances around a process flowsheet and to practical laboratory experience in engineering processes. The module introduces the basic principles and concepts behind basic unit operations used in chemical and environmental processes and applications. The module enables understanding so that students are able to apply separation processes in given applications and use appropriate calculation techniques to size process equipment.Learning Outcomes
A2 Chemical Engineering Principles:
A2.2.1 Understand the principles of material and energy balances and be able to apply them to chemical engineering problems.
Students will demonstrate this through the completion of problems on material and energy balances for multi-unit engineering processes and the determination of multiple unknown characteristics. These will be problems based on theoretical engineering contexts and through the completion of engineering laboratories with primary data gathered. Consequently, these problems will be encountered by students in both their modular examination and in their laboratory experimentations / reports. Both the exam and coursework assessments with re-enforce and support one another.
A2.2.4 Understand the principles of equilibrium and chemical thermodynamics, and application to phase behavior, to systems with chemical reaction and to processes with heat and work transfer.
Students shall demonstrate this through the completion of multiple separation problems involving changes of state of component elements, these will include thermal and phase separation methods. These will be demonstrated through summative examinations at the end of the module.
A2.3.1. Be familiar with the application and limitations of a range of modelling approaches including first-principles models, simple empirical correlations, and artificial intelligence approaches.
Students will demonstrate this through the completion of contextualized problems on multiple component separation processes. These will be demonstrated through the completion of multiple formative assessments throughout the module and in the summative examination assessment at the end of the module.
A2.4.2 Understand and be able to use basic chemical principles to model the characteristics and performance of a range of typical mixing, separation and similar.
Students will demonstrate this through the calculation of different requirements for component separation and through the selection of specific separation methods appropriate for such a separation. These will be demonstrated through the completion of multiple formative assessments throughout the module and in the summative examination assessment at the end of the module.
A2.4.4. Understand and be able to quantify the effect of processing steps on the state of the material being processed, and its transformation to the product in terms of its composition, morphology, and functionality.
Students will demonstrate this through the completion of both theoretical contextualized questions on different reactive and non-reactive systems, but also through the completion of laboratories designed to show students multiple unit operations with energy phase changes and material separations. This will be completed through the summative examination at the end of the module. In addition, the students will take part in a series of laboratory experiments, the consequence of which is a summative engineering coursework report
A2.5.1. Understand the principles of batch and continuous operation and criteria for process selection.
Students will demonstrate this through the generation of a series of different separation techniques using both the batch and continuous processes with material and energy balances associated. The students will be assessed on this topic through a summative examination that has open questions integrated that allow the students to express their understanding.
