This master thesis has the goal of optimizing the operation of a chloralkali electrolytic cell. The process under consideration is a chlorine production plant that is operated as an electrolytic cell with a bifunctional gas diffusion electrode. This electrode enables the operation of the cell in two different modes: a mode of oxygen depletion and a mode of hydrogen production. These modes differ by smaller energy consumption of the first mode and additional hydrogen production of the second mode. Now, the operation and switching between both modes is to be optimized depending on the electricity price. Here, also a necessary cleaning step has to be considered when switching between the modes.

For this thesis, an existing model is to be adopted to both modes. Then different scenarios need to be selected for which an optimal operation is to be determined subsequently.

In this thesis, you will work in GAMS and in gPROMS. (Knowledge of both programs is not required and can be acquired as part of this master thesis).
