    Experimental Modeling of Silicate-Based Geothermal Deposits
    (Elsevier Ltd., 2017) Çelik, Aslı; Topçu, Gökhan; Baba, Alper; Akdoğan, Yaşar; Şentürk, Ufuk; Demir, Mustafa Muammer
    Scaling by metal silicates represents a major obstacle for geothermal systems. A composition that enables the fabrication of artificial deposits is necessary for the rapid testing of potential inhibitors. In this work, artificial deposits were synthesized by employing experimental conditions similar to those in the Tuzla Geothermal Field in Turkey. Although refluxing enabled the formation of a precipitate that was similar to naturally formed deposits in color and texture, their elemental composition and morphology showed a mismatch. An autoclave enabled the production of a precipitate that more closely resembled naturally formed deposits in color, texture, elemental composition, and structure.

    Hydrogeological Properties of Hyper-Saline Geothermal Brine and Application of Inhibiting Siliceous Scale Via Ph Modification
    (Elsevier Ltd., 2015) Baba, Alper; Demir, Mustafa Muammer; Koç, Gonca A.; Tuğcu, Celal
    Scaling is a major obstacle in harnessing of geothermal energy from the geothermal resources. This paper presents a case study for inhibition of metal silicate scaling using formic acid, harvesting more energy in particular case of Tuzla Geothermal Field (TGF), located on Biga Peninsula, in the northwestern of Turkey. TGF is 5. km far from Aegean Sea and 80. km south of Çanakkale. Geothermal fluid of TGF has high salinity (EC. > 91. mS/cm) and medium temperature (reservoir temperature is 173. °C). The acidification of high-salinity brine to mitigate silicate scaling is examined. Results of the study showed that a compromise between scaling and corrosion is achieved by reducing pH of brine to <6 using 55. ppm formic acid.
