Final Thesis

Regeneration of process streams: Potassium sulfate splitting using an electrochemical membrane reactor

Key Info

Basic Information

Chemical Process Engineering
Focus/Key Topic:


Sulphuric acid and potassium hydroxide solution are important basic chemicals in the chemical industry. Potassium sulphate produced in the process is to be regenerated to sulphuric acid and potash lye in order to be able to recycle them into the process.

In this master thesis, potassium sulfate is to be split electrolytically in a two-chamber cell. The process will be investigated for feasibility and evaluated with regard to existing technologies. An existing set up is to be expanded with a larger cell and the set up is to be adapted accordingly. The process will be tested for current density, yields, membrane and electrode stability.

You will be offered:

  • Gaining knowledge in electrochemistry and reactor design
  • Insight into a very innovative field of research
  • Structured approach to complex scientific questions

What we expect from you:

  • Interested in gaining new knowledge (electrochemistry)
  • Enjoy lab-work
  • Structured and independent way of working
