Computer Aided Process Engineering I (Introduction)

Course content

Students can select physical property and phase equilibrium information, which are needed for modelling and simulation of fluid separation processes, especially vapor-liquid based separations. They are able to distinguish and weigh between parameters in addition to create a physical property data file. For a given process flow sheet or separation problem they are able to develop an appropriate reflection in a flow sheet simulation based on the equilibrium stage model. For selected equipment types, such as heat exchangers and distillation columns, they are able to perform a cost-optimum selection and sizing. Overall, they know the typical workflow for fluid process design in the framework of Computer Aided Process Engineering.

Based on the theory for thermal separation processes as presented in “Grundoperationen der Fluidverfahrenstechnik” the typical workflow for process design and optimization is demonstrated. Commercial software products are employed for modelling and simulation of the following tasks:

• Physical properties and phase equilibria: Data retrieval, regression of experimental data, parameter estimation
• Two phase flash: Single stage separations, integral vs. differential operation mode
• Rigorous modelling of a rectification column: Binary mixture, multicomponent mixture, design specifications
• Flow sheet simulation for multistage separation: Feed forward, recycles
• Equipment design: Selection and sizing for distillation columns, heat exchangers, reboilers, condensers
• Costing, process optimization

The lecture is presented in English language at the Institutes Electronic Classroom.
