Process Design (annual)
Instance: 2006/2007 - A
Cycles of Study/Courses
Teaching language
Portuguese
Objectives
To develop capacities of synthesis and analysis of Chemical Processes, in an open framework, in order to identify viable processes and apply criteria to select the best suited one.
To familiarise the students with the techniques of computer-aided process design and the use of chemical process simulators.
To develop an integrated project, working in teams, of a new industrial plant facility or the retrofitting of an existing plant that will include:
definition/selection of an adequate operation sequence (flowsheet);
prepare detailed mass and energy balances;
design and specification of main required process equipment;
preliminary plant lay-out;
estimation of project cost (capital, operation, financial, other) and profitability analysis.
Program
0. Course objectives, contents and evaluation methodology.
1. Introduction to chemical process design (SSL chap. 1).
2. Process creation. Preliminary process synthesis (SSL chap. 2).
3. Computer-aided process design (SSL chap. 3, app.II, app.III).
4. Heuristics for process synthesis (SSL chap. 4).
5. Synthesis of separation trains (SSL chap. 5).
6. Second law analysis (SSL chap. 6).
7. Synthesis of heat exchanger networks (SSL chap. 7).
8. Cost estimation and profitability analysis (SSL chap. 9 e 10)
9. Equipment selection and specification (SSL app.X)
10. Utility generation and distribution (Broughton)
11. Interaction of process design and process control. Brief reference to controllability analysis (SSL chap. 12 e 13)
12. Written process design report and oral presentation (SSL chap.15)
13. Execution of the design of a new process or of the retrofit of an existing plant (prepared by a team of 5 to 6 students).

Eligibility for exams
Minimum weighted average of 10/20 (please, see weighting criteria in the Webpage at the righthand side menu).
Calculation formula of final grade
See Webpage (at the righthand side menu).
Examinations or Special Assignments
See Webpage (at the righthand side menu).
Special assessment (TE, DA, ...)
Because it is essentially a teamwork project a full individual evaluation is not possible. An effective teamwork is required.
Classification improvement
A reformulation and improvement of the final report is required with the agreement of the whole team, plus an oral exam
