The objective of this process design course is to transfer a systematic method for process design. The method taught for the analysis and the design of chemical processes uses methods for “conceptual” design and “process systems design” which have been developed in the last decades. The lectures use fundamentals of this approach and translate them into applications.
The basic disciplines taught in the undergraduate curriculum will be recapped, integrated and expanded. Many aspects of doing an industrial project design will be practiced.|
- Systematic process design starting from "process overall" to conceptual design, Index Flowsheet and Process Flow Diagram (PFD) level;
- Phasing and project organization, how to handle alternatives selection and evaluation of processes and technologies;
- Systematic literature search;
- Functional analysis of existing processes and how to create concepts for improved designs;
- Introduction in process simulation tools, for instance software like Aspen Plus;
- Simulation of the investigated process in a flowsheeter (for instance Aspen Plus);
- Basics of heat exchanger selection and heat integration (Pinch technology);
- Equipment selection and design (down to basic dimensions needed for costing);
- Detailed design of one of the reactor (as application of ACRE);
- Basics and application of process control;
- Basics and application of P&ID's;
- Fundamentals and application of process safety;
- Basics of process economics for economic evaluation;
- Generation and evaluation of process alternatives on technical and economic feasibility;
- evaluating the process design on sustainability criteria (for instance C-efficiency, energy-efficiency)
- Perspectives for future developments will be discussed;
- If possible, the ACHEMA fair will be visited (2018).
About 10 of the 15 EC is spent on the process design assignment, which is carried out in teams of four to five students in parallel to lectures and workshops. Each team will design a different process starting with a limited amount of information and submit their results in a final report,and a presentation (at the owner!). In case of a very good design also an abstract for a conference (general NPS or CHISA) will be submitted. The subjects are for each team and also each year different. Subjects are from industry and different research groups within the department. In general they are related to recent developments.
The final mark is based on the quality of the tests, the progress meetings, final report, presentations and finally the participation in the lectures and workshops. Also an individual self-evaluation of the group and the group members is requested. The outcome of this evaluation can be used to adjust the individual mark.
Only Master students are allowed to participate.
They should have finished ACRE and Advanced Molecular Separation (or being in the process of finalizing these courses). It is also strongly advised to do the master course PED in parallel.
