Paper Description

Edit Paper Description Content

This paper provides advanced aspects of design and process technology that allow students to design systems for commercial production of biological, chemical and mineral products and processing by-products, wastes and water treatment. The course has been designed around total process examples. Principles of chemical, biochemical and environmental engineering will be given including designing production systems, process simulation, heat exchanger design, reactors, fermenters, and separation technologies. The emphasis is on conceptual process design – how to put together an integrated process and how to assess and implement it. A key component in the course is process economics – will the process make money or not and will it be sustainable?

Learning Outcomes

Edit Learning Outcomes Content

Students who successfully complete the course should be able to:

  • Correctly implement the steps in creating process flow diagrams involving reactions, separations, and T-P change operations.
    Linked to the following assessments:
  • Demonstrate how to select the principal pieces of equipment in a process and create a detailed process flow diagram, with material and energy balance and list of major equipment items.
    Linked to the following assessments:
  • Apply heuristics to select appropriate reactor configurations and separation processes for separating solids, liquids, vapours, and vapour-liquid mixtures.
    Linked to the following assessments:
  • Apply systematic methods to determine the optimal sequence of distillation separation processes including sketching the residue curves on a tertiary phase diagram.
    Linked to the following assessments:
  • Design a liquid-liquid and gas-liquid heat exchanger from first principels based on minimal process data
    Linked to the following assessments:
  • Apply process integration methods including pinch analysis for setting minimum energy and water targets for processing plants and for design of optimal heat exchanger or water networks
    Linked to the following assessments:
  • Apply fluid mechanics principles to designing optimal pumping systems including selecting pumps, pipes and fittings
    Linked to the following assessments:
  • Demonstrate a working understanding of process industry economics including market evaluation, capital cost estimation, operating cost estimation and project profitability.

Assessment

Edit Assessments Content

Assessment consists of the following:

Lab assignments and tutorials - due one week after the lab in which the assignments are given (10% of course grade).

These will assess process modelling, and conceptual design aspects as well as more detailed unit operation design.

Project A - Process design - the design brief will be given in first week of the course (10% of course grade).

Project B - Process costing and economics - (10% of course grade).

Combined, these projects assess all the learning outcomes in a unified approach.

NOTE: Both Project A and B must be passed to pass the course.

Test 1 and Test 2 (each 10% of course grade) - open book

Exam (50% of course grade) - open book
