Announcements (previous ones)
- Some questions have been asked about the project report, so I've updated the page:
- particularly on line spacing
- the coverage required for capital and operating costs
- the dates on which you will present (dates were selected to avoid clashes with 4N)
- the presentation format for slides.
- For those modelling processes that are "difficult", such as distillation columns, and for which computer software exists to do your mass and energy balance, please use the software (e.g. Hysys and Aspen). But then your project still has substantial work on designing the column size, and internals of the unit. Here are 2 examples of project reports
- New: for those groups struggling to find information regarding sizing of your project equipment, please check Perry's and the other references suggested on this website.
- Perry's tends to have very practical sizing information and examples.
- Industrial and Engineering Chemistry Research often has rate expressions and lab data which is useful.
- New: Another interesting reference I came across today that will help is in the book "Rules of Thumb in Engineering Practice" by Don Woods. It contains a lot of typical size and flow rates for many units, including many separators. Check out the table of contents online.
- A useful article on designing and understanding adsorbers has been posted.
Based on the large volume of questions I've been getting regarding the course project makes me realize that some extra time and input is required from me to guide you.
- I rather you do this project properly.
- I propose we cancel the teaching part of class on Thursday and Friday. However, I will be in the MDCL room 1110 for any questions regarding your project and presentation during the class hours.
- The timing also works well, because there isn't enough time to start and finish the next section of the course before the presentations.
- The project submission is shifted to Sunday night by midnight (i.e 23:59 on Sunday) to allow you to act on any feedback.
- I'm not going to be available to email over the weekend, so please make sure you get your questions answered by Friday.

- Another change, as announced in class, assignment 5 will be optional. The grades for the assignment portion of the course will be best 4 assignments submitted, so each assignment counts 5%. Now I will make the deal even better for you: if you submitted 5 assignments over the semester, then the assignment that was not used in the best 4, will be a bonus grade, weighing 5%. Example:
- you submit 5 assignments and got: 50%, 60%, 70%, 80% and 90% respectively
- the assignment portion of your course grade will be (60+70+80+90)/4 x 0.20 = 15%
- you get a bonus grade of 50 * 0.05 = 2.5%
- If you hand in 4 or fewer assignments, then there is no bonus grade. This is one way you can boost your grade if you didn't do so well in the midterm.
