CHEM ENG 4050 - Advanced Chemical Engineering

North Terrace Campus - Semester 1 - 2023

This course is composed of two equal parts. Part A is concerned with advanced process dynamics & control. Part B is focussed on particulate properties & design. The course aims to introduce you to advanced process control design tools (Part A). In this section, considerable use will be made of the Matlab & Simulink software packages to specify and design conventional and advanced controllers. As well, design heuristics will be introduced to provide you with the skills to synthesize plant-wide control systems. Part B will focus on particulate technology and its challenges when applied to chemical processing. Key topics to be covered in Part A include: Revision of level III work; analysis & design of controllers by frequency response techniques; analysis & design of complex control systems; practical examples of difficult to control systems; discrete control issues; and, finally, multivariable (MIMO) modelling and control design. Key topics to be covered in Part B include: Storage and flow of powders; solids mixing and segregation; particle size reduction; size enlargement; hazards of fine powders. By the end of this course you should be able to model non-linear dynamic processes, design appropriate analog or digital controllers, deal with interaction in MIMO (multiple input, multiple output) systems, and finally perform basic design calculations and analysis of typical industrial processes involving particulate matters.

  • Assessment

    The University's policy on Assessment for Coursework Programs is based on the following four principles:

    1. Assessment must encourage and reinforce learning.
    2. Assessment must enable robust and fair judgements about student performance.
    3. Assessment practices must be fair and equitable to students and give them the opportunity to demonstrate what they have learned.
    4. Assessment must maintain academic standards.

  • Student Feedback

    The University places a high priority on approaches to learning and teaching that enhance the student experience. Feedback is sought from students in a variety of ways including on-going engagement with staff, the use of online discussion boards and the use of Student Experience of Learning and Teaching (SELT) surveys as well as GOS surveys and Program reviews.

    SELTs are an important source of information to inform individual teaching practice, decisions about teaching duties, and course and program curriculum design. They enable the University to assess how effectively its learning environments and teaching practices facilitate student engagement and learning outcomes. Under the current SELT Policy (http://www.adelaide.edu.au/policies/101/) course SELTs are mandated and must be conducted at the conclusion of each term/semester/trimester for every course offering. Feedback on issues raised through course SELT surveys is made available to enrolled students through various resources (e.g. MyUni). In addition aggregated course SELT data is available.

  • Student Support
  • Policies & Guidelines
  • Fraud Awareness

    Students are reminded that in order to maintain the academic integrity of all programs and courses, the university has a zero-tolerance approach to students offering money or significant value goods or services to any staff member who is involved in their teaching or assessment. Students offering lecturers or tutors or professional staff anything more than a small token of appreciation is totally unacceptable, in any circumstances. Staff members are obliged to report all such incidents to their supervisor/manager, who will refer them for action under the university's student’s disciplinary procedures.

The University of Adelaide is committed to regular reviews of the courses and programs it offers to students. The University of Adelaide therefore reserves the right to discontinue or vary programs and courses without notice. Please read the important information contained in the disclaimer.
