All Research

• Treatment of Emerging Contaminants in Wastewater by Advanced«br /»«br /»«br /» Oxidation Processes (current)

  MSc

  Other supervisor: Prof Chedly Tizaoui

• EG-220 Process and Pilot Plant Operations A

  As a chemical engineer an understanding of how to design and operate processes is vitally important. In one half of this module, students will design a rig based on a given brief. Once designed, the rig will be built and run by the students, and experimental results from tests on the rig will be obtained. In the other half of the module students will be required to research into and report on a given industrial process. The module will involve 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. Overall, each pair of students will conduct 4 different experiments on 4 different pieces of pilot plant apparatus and will be required to produce 4 experimental reports. In each session, each pair of students will conduct various experiments on a piece of pilot plant equipment to obtain experimental data which they will need to analyse and write-up within a lab report. Online videos of will be provided giving guidance on writing reports, handling error and risk assessment.

• 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 School are conducted. The industrial placements are determined by interview with the companies involved or departmental staff. A range of research projects will be offered by the staff.

• EGCM89 Chemical and Environmental Engineering MEng Design Project

  This module aims to advance and broaden the design practices learnt at Level 3. This project will necessitate the students to adapt the design methodologies learnt previously to an unfamiliar molecule in order to generate a novel manufacturing process. The project itself requires the students to develop an innovative design for a plant to make a molecule for which no large scale production facility exists. The molecules to be produced need to be selected on the following characteristics: they should not be manufactured on a large capacity production facility (there may however be small scale production) and an outline of a manufacturing process including basic chemistry exists somewhere. The project will require the students to make choices and judgments on: the production capacity, time of operation, raw materials to use, production process, and benefit of the molecule to the company (ie economic, extending the knowledge base etc). Design is a team exercise throughout and working well as a team is critical to successfully completing this project.

• EGP300 Year 3 Chemical Practical

  This module is a practical catch-up designed to ensure that students have the opportunity to undertake practical skills that may have been missed due to COVID19. As a chemical engineer an understanding of how to design and operate processes is vitally important. In the morning session of this module, students will build a rig based on a given brief. Once built the rig will be run and experimental results from tests on the rig will be obtained. In the afternoon session of this module students will be able to see and run various pilot plant rigs. The module will involve a range of activities to enable students to gain some hands on experience of various experimental equipment.
