Studying online

There are now 3 possible online modes for units:

Units with modes Online timetabled and Online flexible are available for any student to self-enrol and study online.

Units available in Online Restricted mode have been adapted for online study only for those students who require the unit to complete their studies and who are unable to attend campus due to COVID border closures. To be enrolled in a unit in Online Restricted mode, students should contact their Student Advising Office through askUWA and include which of the below criteria applies:

  • You are a student who is currently offshore and unable to enter Australia.
  • You are a student in Australia who is impacted by state or regional border closures.

Details for undergraduate courses
  • Level 3 core unit in the Chemical specialisation in the Engineering Science major sequence
  • Level 3 elective
This unit covers the introduction of the mass and heat transfer principles as it applies to typical unit operations. Topics include (1) heat exchangers; (2) distillation; (3) multi-effect evaporators; (4) liquid–liquid and gas–liquid extraction; (5) solid–liquid separation; (6) refrigeration; and (7) dehydration. The unit also includes applications of the unit operations in the process of liquefied natural gas (LNG) production, transport and re-gasification.
Students are able to (1) write concise technical reports; (2) prepare documentation associated with unit operation design; (3) work in teams; (4) demonstrate information literacy through the location and evaluation of technical and related information as required for assignments; (5) determine the number (trays or units), size and design of unit operations (e.g. gas absorption, liquid–liquid, distillation, cooling tower, etc.); (6) analyse, evaluate and design unit operations with HYSYS and the use of thermodynamic fluid packages; (7) develop strategies for dealing with open-ended problems; and (8) develop abilities to deal with uncertainty in input data and empirical formulae..
Indicative assessments in this unit are as follows: (1) laboratory assignments; (2) quizzes; and (3) a final test. 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.
  • Unit readings, including any essential textbooks, are listed in the unit outline for each unit, one week prior the commencement of study. The unit outline will be available via the LMS and the UWA Handbook one week prior the commencement of study. Reading lists and essential textbooks are subject to change each semester. Information on essential textbooks will also be made available on the Essential Textbooks. This website is updated regularly in the lead up to semester so content may change. It is recommended that students purchase essential textbooks for convenience due to the frequency with which they will be required during the unit. A limited number of textbooks will be made available from the Library in print and will also be made available online wherever possible. Essential textbooks can be purchased from the commercial vendors to secure the best deal. The Student Guild can provide assistance on where to purchase books if required. Books can be purchased second hand at the Guild Secondhand bookshop (second floor, Guild Village), which is located on campus.
