Field of research: Flexibility of chemical and biochemical production plants, module-based plant design, capacity expansion strategies, energy- and resource efficiency of chemical production plants
Increasing economic challenges as shorter product lifecycles and volatile market demands lead to the need for flexible production plants. A promising approach to face these challenges is a modularized production plant. In a modularized production plant, predefined apparatuses with fixed size and design, called equipment modules, are used. Up to now, apparatuses are designed towards minimum costs and highest efficiency for a specific design capacity. When using equipment modules, the focus is moving from the design to the selection of the most suitable equipment module. This leads to reduced time and costs for engineering efforts due to the reuse of engineering work.
Economic considerations proved the advantages of modular plant design. However, an overall approach for modular plant design of chemical and biochemical production plants does not exist yet.
Thus, the aim of my PhD work is the development of an overall approach for modular plant design – “From process simulation to a modular production plant”.
Consequently, my research covers the following topics:
• Decision criteria for/against modularization of plants/apparatuses
• Design of equipment regarding flexibility
• Energy efficiency of equipment modules
• Selection of equipment modules for modular plant setups
• Comparison of plant expansion strategies
By covering all these parts, an overall approach for modular plant design – from process simulation to a modular production plant – will be developed and demonstrated on chemical and biochemical example processes.
Additionally, I am working in the TOP-REF project “Innovative tools, methods and indicators for optimizing the resource efficiency in process industry”. The work covers process modeling of a steam cracker and crude distillation plant, metamodeling approaches and sensitivity analysis for parameter identification.
