The second edition of the European Green Deal – International Project Competition has been organised by the University of Naples Federico II within the Mediterranean PhD School in October 2021.
REFLECT PhD student Serhat Tonkul, from the İzmir Institute of Technology, has received one of the eight awards for his research ‘3D Modeling and Characterization of Stibnite Scaling in High Saline Geothermal Power Plant, Western Turkey‘.
The scaling problem observed in geothermal power plants is one of the most important parameters affecting efficiency. Therefore, it is important to determine the most appropriate reinjection temperature to increase the efficiency of power plants. Within the scope of the study, the stibnite scaling observed in the preheater system of the Germencik geothermal power plant has been examined in full detail. In the geochemical models made for the heat exchanger system, it has been determined that different stibnite species may occur and the appropriate reinjection temperature has been suggested.
