Teaching

  • EG-210 Thermodynamics of Process Design

    This module continues to develop further the fundamentals of thermodynamics studied in the Level 1 course (EGA114). It will develop the general applications needed in process engineering with particular reference to reactor design, separation processes, flow processes, heat engines and energy balance techniques.

  • EG-220 Process and Pilot Plant Operations A

    This module supports and amplifies lectures by providing practical experience of process equipment, its operation, performance and construction. The two components of the module are Equipment Assembly (EA1) and Site Visits. EA1 is carried out in groups of approximately 5 or 6 and the site visits are usually conducted with groups of 5 (with a total of 15 people on each site visit). The module involves a range of activities to enhance team work, report writing, time management and presentation skills as well as to further the understanding of subjects covered in taught modules.

  • EG-230 Process and Pilot Plant Operations B

    This module supports and amplifies lectures by providing practical experience of process equipment, its operation and performance. The Unit Operations Laboratory (UOL) experiments are carried out in pairs. The module involves a range of activities to enhance team work, report writing and time management skills as well as developing further the understanding of subjects covered in taught modules.

  • EG-3062 Process Equipment Design, Selection & Control

    Newly employed graduate process engineers need to be able to perform a wide range of fundamental process engineering calculations. The module will focus on aspects of process engineering design for the majority of equipment but will provide examples of detailed design and mechanical design in some cases. In all cases, industrial standards, best practice and safety will be at the heart of the design process to ensure the finalised designs will be reliable and robust, economically viable, safe and sustainable. The module will include topics such as pump selection, pressure relief calculations, line sizing, utilities, equipment specification including PFRs and stirred tanks in both batch and continuous operation (aseptic/sterile equipment design for regulation and control of chemical and biological reactions). Heterogeneous systems, in particular, the inter-phase mass transfer of nearly insoluble gases. Heat transfer through jackets, coils, electrical heaters and direct steam injection. Sterilisation of liquids and gases..The module also builds upon topics covered in EG-206 (Instrumentation, Measurement and Control) to further develop students understanding of process automation with specific emphasis on the quantitative aspects of control.

  • EGA319 Environmental Engineering Design Project

    This module aims to give Environmental Engineering students experience in handling a complex and integrated process design. This task will require, and so reinforce, the material taught throughout the whole undergraduate course. The module provides training and working in a team environment on a major project and incorporates business skills and sustainability.

  • EGA326 Chemical Engineering Design Project

    This module aims to give students experience in handling a complex and integrated engineering process design. This task will require, and so reinforce, the material taught throughout the undergraduate course and an additional amount of material from directed private study. The module provides transferable skills related to for working in a team environment on a major project.

  • EGA332 Applied Process Engineering

    Newly employed graduate process engineers need to be able to perform a wide range of fundamental process engineering calculations. This module is designed to equip students with the knowledge required for them to start a process engineering job. The module will include topics such as pump selection and design, pressure relief calculations, equipment specification, commissioning, how to write unambiguous procedures and how to interpret complex P&ID's.

  • EGC401 Industrial Engineering and Research Practice

    This module aims to give students practical experience in either the industrial setting or the research environment. Either two day placements in industry or two day research placements within the College of Engineering are conducted. The industrial placements are determined by interview with the companies involved or College staff. A range of research projects will be offered by the College staff. The module aims to reinforce and deepen material taught previously in the undergraduate environment and broaden practical skills learnt during the previous years. The module will provide an opportunity to apply to industrial/research problems the knowledge obtained within the undergraduate course. The module will also give experience in teamwork, communication, presentation and planning skills plus where appropriate the experience of the management structures and practices of industrial organizations or research projects.

  • EGCM33 M.Eng Research Project

    This module aims to give an introduction to research methods and the research environment, by undertaking small projects linked to larger research programmes in the College, carried out by staff, research assistants and postgraduate students. The work can involve experimental, theoretical and/or computational work, and is presented for assessment in a report and a presentation. A range of projects will be offered by various staff.

  • EGCM36 Desalination

    Desalination is an important process in the management of water resources and it has a large societal, economic and environmental impact. This module will give engineering students a solid grounding in desalination and related separation processes. This will prove invaluable for a future career in many areas of engineering.

  • The formation of bacterial biofilms at surfaces is a significant problem in many industries and medicine. Biofilms often lead to the failure of processes such as water management, food production and medical implant techniques. At Swansea University we are developing novel methods that disrupt biofilm formation at surfaces and are looking to recruit a doctoral student to undertake a research project optimising biofilm control methods. The research of the project will be in collaboration with industry as part of an EngD sponsored by the EPSRC. The student will use advanced surface and particle characterisation techniques alongside flow chamber hydrodynamic shear assaysto study the formation and control of industrially relevant biofilms. The work wil ltake place within the Multidisciplinary Nanotechnology Centre and the Centre for Nano-Health at Swansea as part of the COATED Centre for Doctoral Training. (current)
