Niedertemperaturwärme im Bereich von 100 °C - 200 °C kann mittels Organic Rankine Cycles (ORC) zur Stromproduktion genutzt werden. Zur Untersuchung von Optimierungsmöglichkeiten bei ORC-Prozessen wird am KIT die Testanlage MoNiKa (Modularer Niedertemperaturkreis Karlsruhe) aufgebaut. Diese Arbeit beinhaltet eine thermodynamische Auslegung des Prozesses und darauf aufbauend die Implementierung eines dynamischen Simulationsmodells, das eine detaillierte Analyse des Teillastverhaltens ermöglicht. Low temperature heat between 100 °C - 200 °C can be used for power production via Organic Rankine Cycles (ORC). In order to study the optimization possibilities of ORC processes, the test facility MoNiKa (Modular low-temperature cycle Karlsruhe) is being built at the KIT. This work contains a thermodynamic design of the process and the implementation of a dynamic simulation model which allows for a detailed analysis of the part-load performance.

Fiber-reinforced materials offer a huge potential for lightweight design of load-bearing structures. However, high-volume production of such parts is still a challenge in terms of cost efficiency and competitiveness. Numerical process simulation can be used to analyze underlying mechanisms and to find a suitable process design. In this study, the curing process of the resin is investigated with regard to its influence on RTM mold filling and process-induced distortion.

This master’s thesis focuses on the development and optimisation of a post-combustion CO2
capture plant utilising membrane separation. The primary goal is to design a configuration
that meets operational requirements while minimising power consumption and equipment
costs. Ensuring system durability by minimising condensation within critical components,
including an atom-thick membrane, is also a key objective. This involves the conception
of a cooling and drying unit to remove humidity from the flue gases. Additionally, the
thesis addresses the preliminary design of the compressor-turbine unit (CTU), incorporating
small-scale turbomachinery and gas-lubricated bearings.
The initial design phase consists in simulating multiple configurations using Aspen Plus,
which enables quick evaluations and the elimination of non-feasible options. However, Aspen
has some limitations in optimizing complex systems, which are overcome by using a custom-
coded Matlab model, offering greater flexibility and control over key parameters. The thesis
ultimately compares different feasible configurations and determines the Pareto front of one
process layout depending on several design parameters.
The conclusion emphasises the need for further refinement of the models and accurate equip-
ment sizing. A detailed analysis of capital and operational expenses associated with addi-
tional plant equipment is also recommended to identify the most cost-effective solution.
