Details for undergraduate courses
  • Level 3 core unit in the Chemical specialisation in the Engineering Science major sequence
  • The area of knowledge for this unit is Mathematical and Physical Sciences
  • Category B broadening unit for students
  • Level 3 elective
This unit develops the student's ability to formulate and solve material and energy balances for chemical process systems. Students analyse material balances for multi-unit process systems with and without chemical reactions, including systems that incorporate recycle and purge. Analysis of these systems develop understanding of and the ability to calculate the thermodynamic properties of gases, liquids and vapours. Energy balances based on the first law of thermodynamics are formulated for systems with and without reactions.
Students are able to (1) understand written process descriptions and turn them into accurate process flow diagrams; (2) write concise and accurate reports; (3) extract relevent data from complex scientific and industry reports; (4) design, construct and interpret static process flow diagrams using commercial software; (5) assess the quality of data available from commercial modelling software; (6) use steam tables and other standard tables of engineering data to find required data; (7) estimate system properties when exact values are not available and determine the limitations of these estimates; and (8) solve static material and energy balances.
Indicative assessments in this unit are as follows: (1) assignments; (2) hysys exercises; and (3) a final examination. Further information is available in the unit outline.

Supplementary assessment is not available in this unit except in the case of a bachelor's pass degree student who has obtained a mark of 45 to 49 overall and is currently enrolled in this unit, and it is the only remaining unit that the student must pass in order to complete their course.

  • The availability of units in Semester 1, 2, etc. was correct at the time of publication but may be subject to change.
  • All students are responsible for identifying when they need assistance to improve their academic learning, research, English language and numeracy skills; seeking out the services and resources available to help them; and applying what they learn. Students are encouraged to register for free online support through GETSmart; to help themselves to the extensive range of resources on UWA's STUDYSmarter website; and to participate in WRITESmart and (ma+hs)Smart drop-ins and workshops.
  • Books and other material wherever listed may be subject to change. Book lists relating to 'Preliminary reading', 'Recommended reading' and 'Textbooks' are, in most cases, available via the Booktopia Textbook Finder, which has the functionality to search by course code, course, ISBN and title, and may also be posted or available at the appropriate school's administrative offices. Where texts are listed in the unit description above, an asterisk (*) indicates that the book is available in paperback.
