• A lot of positive comments regarding Monday's troubleshooting exercise. I'm glad that most of you found it a useful learning tool and in future years I will have 2 tutorials on this topic. Don't worry about the grading too much on this one; we recognize this is your first attempt at troubleshooting, and it was especially hard for the first troubleshooter in the triad. Remember what you learned today (i.e. what you wrote in the evaluation) and try to apply it in the final exam: I want to and I can!
• The full notes for the Process troubleshooting section have been posted.
• It is extremely important that you collect a binder from me in class on Thursday or Friday. If you fail to collect this binder before the weekend, then the troubleshooting tutorial on Monday (assignment 8) will be a failure. This binder will contain a troubleshooting exercise that you must read before the tutorial on Monday.
  • If you cannot make it to class, please come by my office anytime on Thursday or Friday.
  • Please note, this tutorial counts for 20 points of your course grade. Not showing up at the tutorial, including being late, implies a zero, but more importantly lets down 2 of your colleagues in the class, because the entire triad depends on YOU!
  • If you cannot attend, provide a written explanation to me by Friday at noon.
  • You will work with 2 other people in the class; neither of the 2 will be existing group members.
  • There is no written submission after the tutorial. Everything is done during the tutorial time. It is not possible to "make up" this tutorial, due to its interactive nature.
• There will be class all week on 13, 15 and 16 November to cover the final topics: operability and process troubleshooting.
• Tutorial/assignment 7 is now posted and is due on 13 November 2012 at class.
• Important: Several announcements from other professors will be made at class on Tuesday, 13 November. Please attend if you can.
• Slides for class on Tuesday (13 Nov) will cover small parts of the larger operability topic. I've assembled the slides I will speak on into a single PDF. Please print for class on Tuesday, or print out after class for reference.
• Operability notes with solutions have been posted.
• Two useful resources relating to this week's classes (week 10) and assignment 7:
  • A free PDF chapter from Turton's textbook on flow diagrams
  • Instrumentation for process control: click on the section 2 on Sensors on the left hand side to learn how flow, temperature, level and other sensors work.
• No tutorial next Monday, 12 November: please use the 2 hours to work on your SDL projects.
• Grades for assignment 1, 2, 3 and 4 are posted on Avenue. Please sign in to check. Assignment 5 and 6 grades will be posted soon.
• (Partial) midterm solutions are now available. The remaining solutions were covered in class.
• The guest lecture on Thursday, 01 November: "Introduction to Innovation and Entrepreneurship" is now available on video.
• An import memo regarding the SDL projects and next steps. Meetings with Alicia (group A's) and myself (group B's) may be scheduled from 13:00 to 19:00, Tuesday to Friday. Book them early to ensure you get a slot that works for your group.
• Information about the midterm on Monday has been available for some time. Please make sure you bring the necessary materials with you to the exam. There are some practice problems also available.
• Salary figures for Chemical Engineers between age 26 and 35
• Some hints for the assignment 5:
  • Updated: The due date is Tuesday 23 October, at class.
  • Costing should be done for 2011.
  • Cost of steam: a publication from the DOE.
  • Another good article on pricing steam
  • From the above 2 articles you will gather that steam generation is a complex "mini-plant" in its own right, usually generating it using natural gas as an energy source. So if you find an outdated steam price, ratio it against the price of natural gas to get current pricing.
  • ACO pricing is hard to come by, but ACO has similar physical properties to palmitic acid, or hexadecanoic acid. In the absence of better information, you may use this for pricing instead.
• Update on the midterm : the midterm has been rescheduled to 29 October 2012, starting at 19:00 (please be at the venue from 18:45 onwards). It will be written in T29, room 101. As requested in the course evaluation, some practice questions have been posted.
• Assignment 5 for Monday is posted.
• Based on the course evaluation feedback, there is now a discussion board available on the Avenue2Learn website. Please participate!
• As promised, an example of self-directed learning report for 4N4 produced by a group in the 2011 class. There will be a memo with an update on the next steps for the SDL project in the next few days where you will have to write an outline of your project's scope.
• Question for class on Thursday:

Estimate the capital cost for a distillation column fabricated from 316 stainless steel, 26 trays at regular spacing of 0.6m, operating at 3.2MPa. The column height is 21.3m and diameter of 2.3m.

• Solutions for both assignment 2 and 3 are available; see below. Paper copies will be returned in class on Thursday.
• A reading on the Chemical Engineering Plant Cost Index (CEPCI)
• The informal course evaluation results.
• An update regarding electronic submissions: a single Word document or PDF or Google Doc (preferred) will be accepted. Please read for more details.
• Inflation adjustment factors for the process industries
• 2 slides on the bare module method
• A list of costs that should be considered
• You will also require portions of Don Woods' book Cost Estimation for the Process Industries. This can only be downloaded from McMaster computers [30 Mb]. Please keep a copy for tutorials and use in class exercises. You do not need to print the entire book, only the parts from chapter 1. The other chapters are for reference.
• We'd like to be clear: a spreadsheet by itself is NOT a valid assignment submission and will essentially receive a grade of zero: it's as if handing in a report to your manager with only appendices but no content. Furthermore, we are seeing groups that do not follow the requirements posted a week ago: non-native Google Docs do not show up correctly and cannot be commented on by the TAs or myself.
• Assignment 4 is posted for Monday's tutorial.
• A short note regarding cover letters has been posted.
• For assignment 3, question 5: please use an MARR of 15%. The assignments are due at the start of your tutorial time slot; if handing in electronically, please make sure we get them by 17:00.
• A memo has been posted, dated 24 September 2012. We will discuss this in class on 25 September.
