CHEMICAL ENGINEERING DESIGN PROJECT A

The key aim of this module is to prepare graduates with technical and leadership qualities.The more specific aims are:

• To ensure students gain professional expertise by completing fundamental design of a chemical plant through individual and group based tasks.

• To be able to integrate their knowledge and understanding of engineering, mathematics, science, and computer-based methods with economic, environmental, social and ethical principles to design new processes or products.

• To grasp importance of sustainability in chemical engineering practice and to incorporate sustainability principles at the design stage of new products or processes.

Tasks are concerned with the gathering of sufficient information and project background details. Specific tasks will vary but will usually include:

1.  Decide on the main chemistry and select a suitable process route.

2.  Look for similar flowschemes or build up the flow scheme using literature searches (as guidance).

3.  Identify key unit operations and make sure that both their function and purpose is clear.

4.  Collect possible operating conditions – these may change as the group gathers more process information and knowledge.

5.  Prepare the flowscheme that will be used.

6.  Complete material and energy balances – this requires knowing or estimating the composition of the reactor effluent, estimating performance of equipment, setting the specifications of separation processes, etc.

7.  Address and scope control, safety, cost and sustainability issues.

8.  Split the process into sections, each section should contain a major process unit, or a number of units, that can be used to demonstrate individual chemical engineering knowledge.

9.  If time permits, and after receiving feedback, correct the flow schemes and initial scoping design and start more detailed technical work.

During the period of the project, group members will be allocated specific tasks which benefit the group, particularly during the final stages when reports are being authored. For example, someone should be allocated to cover the following: the overall economic appraisal of the process; an overall draft of the entire process PFD; a written section covering the overall process description; a critical assessment of assumptions  and their impact on the  reliability of  the design; assembling and authoring the report, etc..

Depending on circumstances, it would normally be expected that these sections be contained within the group project report. Sections authored by individual group members must be clearly associated with the author and the use of a formal document style is encouraged; a style similar to this document, with headers & footers identifying individuals responsible for each section, is acceptable.
