The research is conducted in collaboration with another three University Departments (IFK of Stuttgart University, University of Appllied Sciences Zittau / Görlitz FH and VWS of the TU-Dresden). The two sub-projects of the IET comprise studies at first of the retention of SO_x und NO_x during cooling and compression of the exhaust gas. Furthermore, a systematic overall process analysis for the Oxyfuel power plant will be performed, while considering various configuration schemes for the flue gas cleaning plant.

In the first sub-project, experimental measurements will be performed in the CO₂ separation rig of the IET. Oxyfuel exhaust gases, both synthetically mixed or generated as real flue gases with the Drop Tube Furnace of the Institute, will be ocmpressed, so that the CO₂ can be liquefied. The water condensate will then be analysed chemically to determine its composition and mass balance (SO_x, NO_x). This information will then help analyse the wear and corrosion potential on the CO₂ condenser. In the second sub-project the behaviour of selected equipment components of the Oxyfuel power plant (Flue Gas Desulphurisation, Electrostatic Precipitator, Denox Catalytic Converter, Pulverised Fuel Dryer) will be studied in detail. Aided by results from the first IET sub-project, the overall plant configuration will be simulated, to identify improved integration approaches and evaluate their overall economics.

Through this study important aspects, which after the completion of the project ADECOS still remain open, can be addressed. Especially the retention of CO₂ impurities in the waste condensates and the optimisation potential from different technical approaches can now be investigated in detail.
