Catelog Description

This course comprises many of the standard operations in chemical plants such as gas absorption, heat exchange, distillation and extraction. The design and operation of these devices is emphasized. Prerequisites: 06-321 and 06-323.

Course Objectives:

To learn the principles needed to size equipment used for physical transformation of process streams. Understand role of mass transfer and phase equilibrium. Compare co-current and countercurrent contacting of streams.

Specific Topics:

Specific equipment includes shell-and-tube heat exchangers, single and multiple-effect evaporators, batch still, tray columns for distillation, packed columns for gas absorption and stripping, membranes for gas separation and liquid-liquid extractors.

Textbook:

This web site will accumulate an updated version of the class notes and will be used to post solutions to homework assignments and past exams. Most postings are in the form of Adobe PDF files.

Grading:

10% Homework & Project
60% Two in-class exams (Feb. 23, Apr. 6)
30% Final Exam (TBA)

Project:

A brief written summary of some unit operation of your choice. You can choose any unit operation (equipment sizing for physical transformation) you like as long as it's not one which I cover in class. The final report should be about 10 pages in length and I expect you to spend about the same total time on this assignment as the two weekly homework assignments it replaces.

Computer Tools:

Use of Mathcad is encouraged in all homework problems. Modules are provided to demonstrate 1) working with units, 2) interpolating tabular data (e.g. steam tables), and 3) programming (e.g. McCabe-Thiele method). Chemsep is employed to perform tray calculations for multicomponent distillation
