About the Project

Currently we are developing two different types of membranes targeting different separation tasks as outlined below:

Ultrafiltration membranes for water treatment

The phase-out of coal as the fuel in power generation will cause an increase in the use of biomass in co-generation power plants. The flue gas from the combustion will contain some heavy metals. The EU industrial emissions directive requires power plants to invest in technologies that increase the efficiency of the plants with particular emphasis on flue gas condensation, as it enhances efficiency and reduces the emission of pollutants such as soot and heavy metals. The associated environmental issues with these pollutants demand the purification of the condensate before their release/reuse. To reach the required purity one needs to use the reverse osmosis (RO) process. For an efficient and economic RO purification process, a prior ultrafiltration (UF) step is required for safe re-use of the water. Thus, the development of ultrafiltration solutions play a key role in the purification of condensate.

Together with an industry, we have recently won support, from the Danish Environment Protection Agency, for development of such Ultra Filtration membranes for wastewater treatment. The project addresses manufacture of UF membranes using optimized ceramic processing methods like extrusion and dip coating. The optimization involves slurry/paste formulation enabling co-sintering. Pastes will be characterised with respect to rheological behaviour and the finished membranes with respect to structural and chemical stability.

Electrochemical gas separation membranes

For the synthesis of ammonia, which is an important chemical for fertilizers and a potential green fuel for maritime transport, one needs a pure reactant stream of Nitrogen. This can be realised by electrochemically pumping out the oxygen from air – resulting in a stream of pure Nitrogen and a stream of pure Oxygen. The oxygen may advantageously be used for gasification of biomass or in oxy-combustion schemes where carbon capture is desired. Hence, such separation devices may have several uses.

Within the framework of a Horizon2020 EU project, we are trying to develop such separation devices. They are based on ionic conductors like Cerium oxide and are manufactured by tape casting. Suitable electrodes must be applied e.g. by screen-printing on both surfaces to provide electrical contact and to catalyse the process.  The project targets to prove the concept by manufacturing and successfully testing such a device


About Solid State Chemistry

The research in the Section of Solid State Chemistry (SSC) comprises many aspects including:

  • Advanced instrumentation, including electrochemical impedance spectroscopy on cells and in stacks
  • Operating conditions ranging from lab (clean gasses) towards real life (including impurities in different fuels, dynamic profiles, higher pressure)
  • Safe operation regarding work environment and for cells/stacks combined with high degree of automatisation, including remote control and data logging
  • Combination of tests with modelling on different levels

Other Benefits

DTU is a leading technical university globally recognized for the excellence of its research, education, innovation and scientific advice. We offer a rewarding and challenging job in an international environment. We strive for academic excellence in an environment characterized by collegial respect and academic freedom tempered by responsibility.

Notes

  • The appointment will be based on the collective agreement with the Danish Confederation of Professional Associations. The allowance will be agreed upon with the relevant union.
  • If you are applying from abroad, you may find useful information on working in Denmark and at DTU at DTU – Moving to Denmark.
