10.10  Intro to Chem Engineering

You may use your textbook (Elementary Principles of Chemical Processes, by Felder and Rousseau), lecture notes, and any notes that you have taken yourself during class. A calculator is allowed. No other electronic devices are allowed.  

Dear students,

A sample exam, with solutions, has been posted.

As you study for 10.10 and other subjects, you will come to some conclusion about how well you have mastered the subject matter.  This would be an appropriate time at which to complete the end-of-term subject evaluations.  Please do, because we pay attention - several features of 10.10 have come about, and several deleted, because of student input.  We have a common goal of offering really good courses, and part of that is up to you.

Hello Everyone-

Today’s office hours have been moved to Saturday, the 13th of December, to be closer to the exam. Additionally, please remember that there are several resources available to help you prepare for the final. The first is a review during recitation tomorrow morning. Amanda and I have office hours in the computer room (66-070) on Thursday and Saturday this week from 3PM to 7PM. The instructors also have office hours, see the website for details. The ChemE department has undergraduate tutoring. And as always, you can email us at 10.10ta@mit.edu with questions.

Dear 10.10 Class,

This is just a reminder that we have guest speakers who will talk about various aspects of Chemical Engineering on Monday and Wednesday.   Please note that there will be some credit given toward things touched on in the talks in the final exam.   
This Monday, Dec 8,  you will hear from two MIT Chemical Engineering faculty and their perspectives on their work and the Chemical Engineering Field:

Heather Kulik - quantum mechanical methods to understand and design heterogeneous, molecular, and biological catalysts:  http://hjklol.mit.edu/

William Tisdale - nanomaterials for renewable energy applications:

You've lumped your liquid components into light-key and heavy-key; now your task is to specify how you would like them to separate in the column.  Specifying xD and xB is one way to do that, but I've found that you have much more control over the column behavior if you instead specify:

LKsplit (= mole flow LK in distillate/mole flow LK in bottoms)
HKsplit (= mole flow HK in distillate/mole flow HK in bottoms)

and THEN calculate the xD and xB that result.  This shouldn't change most of what you're already doing, but it's a lot easier to get the column to do what you want when you work directly with the flow rate ratios.  If you're doing fine, don't change anything, but if you're having trouble with recycles, this may be the trick.
