Course summary

Process development lecture

Welcome to the process development lecture. The process development lecture is a project-based course where you will learn the principles of process development.

The course introduction and information material, including the course outline and the gates and missions of the course, are available here.
You have the possibility of applying to the Student Contest Problem, a challenge for CAPE-students who have to suggest solutions to a broad chemical engineering problem by the European Symposium on the use of computers in Chemical Engineering from the European Federation of Chemical Engineering :

SCP2025 – Manufacturing Chemical Products from CO2 using Renewable Energy Resources (NEW LINK!)


Gate 1: Main Process Options (February 17 - March 10)

Gate 1 missions are available here


To reach Gate 1, you must define the main process options that you have identified for the desired product. To reach the gate you have to:
  1. Chemically and thermodynamically characterize your product
  2. Economically characterize your product
  3. Make a literature search to identify the major production routes
  4. Decide the process options by comparing the main process routes

Gate 2: Process Flowsheet Simulation (March 17 - April 28)

Gate 2 missions are available here


To reach gate 2, you will have to develop a process flowsheet model for the production routes that you have identified and complete the following missions:
  1. Define the appropriate thermodynamic properties model for your system
  2. Define the process unit operation models
  3. Draw a flowsheet by interconnecting process unit operations
  4. Make a summary of the assumptions and the decision variables related to the process model
  5. Converge the process model for a given set of decision variable values
  6. Calculate the size of the main process equipment
  7. Determine and calculate the process performance indicators
  8. Extract and report the key flowsheet performance descriptors
  9. Do a sensitivity analysis of assumptions, data uncertainty or decision variables

To have an overview of Gate 2, go to the MIRO board

Gate 3: Process Integration (May 05 - May 26)

Gate 3 missions are available here

Gate 3 aims to identify the way to close the energy balance of the system by defining:
  1. The heat recovery in the system
  2. The energy resources to be used
  3. The integration of energy conversion units

To have an overview of Gate 3, go to the MIRO board


Gate 4: Proposed Process Design and Conclusion (May 05 - May 26)

Gate 4 missions are available here


To reach gate 4, you will have to propose the best final design for your process. You will be asked to:
  1. Calculate the best operating conditions and equipment sizing of your process design
  2. Report the process designs that you are proposing for the final decision
  3. Compare the performances of the process with multiple criteria like economical, environmental, hazards and operability criteria
  4. Recommend a process design for the final decision
