MT: Development of a flowsheet model for scaling of process steps in wet-oxidative gas desulphurisation - contact Philipp Wagner

Wet oxidative gas desulphurisation is an efficient process step to remove H2S from industrial (waste) gases. A scrubbing solution with a redox catalyst is used, which oxidises the dissolved H2S to elemental sulphur. This then precipitates as a solid and can be separated and used as a valuable material. This process has already been investigated in a project and initial modelling approaches have been formulated.
In order to enable scaling up to industrial scale, a valid model should be developed, depending on its suitability, the software ChemCAD is used with standard units and "User Added Modules" or the model is developed in Python, taking into account previous results. This results in the following tasks.

BA/RP: Simulation of a integrated sorptive ammonia separation - contact Carl Sengoba

MT: Extension of a Rate-Based Model for a Rotating Packed Bed (RPB) in Mosaic Modeling - contact Joshua Orthey

A promising method for efficient CO2 separation is chemical absorption using aminebased
washing solutions. This method stands out due to its high selectivity, enabling
targeted removal of CO2 from product or exhaust streams. Even under low pressure,
chemical absorption allows for effective CO2 separation.

To implement this method, a novel type of packed column/reactor called RPB
(Rotating Packed Bed) is utilized. In a previous effort, a foundational framework for
a Rate-Based Model was already developed. The main objective of the upcoming
master's thesis is to further optimize the model by integrating additional components.

FP/BA/MA: Adaptive Sampling in Parameter Space for Creation of Data-Driven Surrogate Models - Contact Torben Talis

The DFG project "Safe Reinforcement Learning for Start-up and Operation of Chemical Processes" aims to develop a systematic approach to implement and study reinforcement learning under real conditions in complex chemical processes in order to optimize dynamic operation under process constraints.

The generation of good training data is essential for the creation of surrogate models.

MT: Knowledge Graphs to Model Chemical Engineering Knowledge and Data - contact Erik Esche

As part of the "Semantic Web", "Knowledge Graphs" have become a popular method
to make knowledge available. The topic of this master thesis is the linking of engineering knowledge with other sources via knowledge graphs.

BA & MA: experimental and theoretical determination of the oxygen saturation concentration in a water glycerol solution - contact Johann Weigelt

In industry, the saturation concentration is an important factor for the absorption of gases in areas such as the food and chemical industry. The factors temperature, partial pressure and material properties play a decisive role. A precise understanding of these relationships contributes to the optimization of industrial processes.

MA: Modeling the fluid dynamics of tray columns - contact Patricia Polgár & Hannes Raddant

The experimental investigation of absorption and distillation columns is time consuming and limited in technical realization. A tray model needs to be developed to
describe the fluid dynamics and mass transfer inside these columns at different steady state and dynamic operation conditions. This model will be used for the
validation of experimental data and for the description of unsteady plant operation in the future.

RP, BA or MA: Process automation and AI based image recognition for dynamic phase separation in microemulsion systems - Contact person Karsten Duch

We are investigating homogeneously catalysed processes in liquid multiphase systems. In particular we are looking at the hydroformulation of long chained olefins in microemulsion systems and are implementing the process in a mini-plant. The Idea behind using a microemulsion system is to use the advantages of a very efficient homogeneous catalysis and combining them with a simple phase separation step for a reliable recovery of the catalyst. The advantage of a microemulsion system is that the phase state (2 or 3 phase) is temperature dependant and can be switched by changing the Temperature.
