Module summary

This module covers how chemical products may be produced on a large scale commercially. Sources of raw materials and processing techniques are investigated, both using traditional technologies and new approaches in order to lower the overall environmental impact. This module will appeal to those who have an interest in how to produce chemical products more sustainably in the future.

Module aims

The production methods of many chemicals are changing rapidly driven partly by the need to reduce costs but more especially by the search for ‘cleaner’ processes. This module will explore the current methods for producing chemicals and seek to predict where the chemical industry is heading.

The module starts with consideration of the effects of legislation and public concern, concentrating on the cradle-to-grave approach, from obtaining the raw material to the disposal of the used product. Current manufacturing methods will be explored including raw materials extraction, their processing and technology aspects and the uses of particular products before consideration of ‘clean’ alternatives. Finally we will round off with a series of recent case studies.

Module learning outcomes

  • to identify and define the three components of a Life Cycle Assessment
  • to describe the background and nature of green chemistry
  • to calculate the environmental impact of a chemical synthesis using appropriate metrics
  • to describe the extraction of current feed stocks for the chemical industry and their processing into useful chemicals
  • to discuss recent examples of chemistry, solvents, catalysts, processes and reactors with the aim of reducing the environmental impact of chemical manufacture
  • to describe and calculate the design features of a full-scale chemical plant, including reaction, distillation, heat transfer and mass transfer processes

Workshop

Workshops: There will be one workshop associated with the Case Studies and one workshop associated with the chemical processing topic.

Prerequisites: Knowledge of chemistry to Year 1 undergraduate level is required. No prior knowledge of environmental science, chemical engineering or industry is assumed.

Assessment: Assessment of the Chemical Case Studies workshop will contribute 30% toward the value of the module with the 1.5 h written examination contributing the remaining 70%.

Module feedback

The closed examinations are marked typically within 10 days with mark slips (with per-question break-down) being returned to students via supervisors. Outline answers are made available via the Chemistry web pages when the students receive their marks, so that they can assess their own detailed progress/achievement. The examiners reports for each question are made available to the students via the Chemistry web pages.

The information on this page is indicative of the module that is currently on offer. The University is constantly exploring ways to enhance and improve its degree programmes and therefore reserves the right to make variations to the content and method of delivery of modules, and to discontinue modules, if such action is reasonably considered to be necessary by the University. Where appropriate, the University will notify and consult with affected students in advance about any changes that are required in line with the University's policy on the Approval of Modifications to Existing Taught Programmes of Study.
