CHNG4806: Chemical Engineering Design B

Semester 2, 2021 [Normal day] - Camperdown/Darlington, Sydney

In the overall design process, chemical engineers must clearly understand the (often complex) interactions and trade-offs that occur between technical, economic, social and environmental considerations. This unit of study builds on concepts in each of these areas introduced in previous years but with an emphasis on their successful integration within a comprehensive design activity. This design activity is spread over two units (Chemical Engineering Design A and B) run in first and second semester. The primary aim in the first unit is to consider the technical issues- with an emphasis on creating and evaluating a range of alternative options that exist at both the unit operation and complete flowsheet levels. The primary emphasis in this unit is on evaluating how non-technical considerations affect the final process design and its operation. Students joining this course from the Major Industrial Placement Project (MIPPs CHNG 4203) or as overseas students (with approval) do the same assignment but on a different schedule.

Assessment summary

  • Part A: The Executive Summary    
  • Part B: The overall process design
  • Part C: Detailed equipment design - Individual members of the team will nominate individual items of equipment for more detailed investigation and design.
  • Part D: The review of the design including the HAZOP and optimisation.

Detailed information for each assessment can be found on Canvas.

Assessment criteria

The University awards common result grades, set out in the Coursework Policy 2014 (Schedule 1).

As a general guide, a high distinction indicates work of an exceptional standard, a distinction a very high standard, a credit a good standard, and a pass an acceptable standard.

Result name

Mark range


High distinction

85 - 100



75 - 84



65 - 74



50 - 64



0 - 49

When you don’t meet the learning outcomes of the unit to a satisfactory standard.

For more information see guide to grades.

Late submission

In accordance with University policy, these penalties apply when written work is submitted after 11:59pm on the due date:

  • Deduction of 5% of the maximum mark for each calendar day after the due date.
  • After ten calendar days late, a mark of zero will be awarded.

Academic integrity

The Current Student website  provides information on academic integrity and the resources available to all students. The University expects students and staff to act ethically and honestly and will treat all allegations of academic integrity breaches seriously.  

We use similarity detection software to detect potential instances of plagiarism or other forms of academic integrity breach. If such matches indicate evidence of plagiarism or other forms of academic integrity breaches, your teacher is required to report your work for further investigation.

You may only use artificial intelligence and writing assistance tools in assessment tasks if you are permitted to by your unit coordinator, and if you do use them, you must also acknowledge this in your work, either in a footnote or an acknowledgement section.

Studiosity is permitted for postgraduate units unless otherwise indicated by the unit coordinator. The use of this service must be acknowledged in your submission.

Simple extensions

If you encounter a problem submitting your work on time, you may be able to apply for an extension of five calendar days through a simple extension.  The application process will be different depending on the type of assessment and extensions cannot be granted for some assessment types like exams.

Special consideration

If exceptional circumstances mean you can’t complete an assessment, you need consideration for a longer period of time, or if you have essential commitments which impact your performance in an assessment, you may be eligible for special consideration or special arrangements.

Special consideration applications will not be affected by a simple extension application.

Using AI responsibly

Co-created with students, AI in Education includes lots of helpful examples of how students use generative AI tools to support their learning. It explains how generative AI works, the different tools available and how to use them responsibly and productively.

Study commitment

Typically, there is a minimum expectation of 1.5-2 hours of student effort per week per credit point for units of study offered over a full semester. For a 6 credit point unit, this equates to roughly 120-150 hours of student effort in total.

Learning outcomes are what students know, understand and are able to do on completion of a unit of study. They are aligned with the University's graduate qualities and are assessed as part of the curriculum.

At the completion of this unit, you should be able to:

  • LO1. work effectively within a team to deliver a common objective
  • LO2. identify knowledge gaps and evaluate the technical literature to close the knowledge gaps as it applies to the design of the proposed process flowsheet
  • LO3. evaluate and optimise alternative process flowsheet designs to ensure compliance with the specified performance requirements
  • LO4. construct a complex process flowsheet with reference to the specified performance requirements, while dealing with competing objectives and constraints
  • LO5. apply prior knowledge of unit operations to design a unit operation within a proposed process flowsheet, including the application of chemical engineering design tools
  • LO6. undertake hazard assessments, hazard operability studies and comprehensive environmental impact assessments on a proposed process flowsheet.
  • LO7. communicate complex technical information to a broad audience
