Gasification kinetics of Thrace region coal by thermogravimetry analysis
Kök, Mustafa Verşan; Yildirim, Betul (Elsevier BV, 2020-05-01)
This study aimed at understanding the gasification kinetics of Thrace region coal samples performing isothermal carbon dioxide gasification experiments at five different temperatures (750, 825, 850, 900, 950 degrees C). Th...
The effect of water on combustion behavior of crude oils
Kök, Mustafa Verşan; Varfolomeev, Mikhail A.; Nurgaliev, Danis K. (Elsevier BV, 2020-03-01)
The ramped temperature oxidation experiments were performed on heavy and light crude oil samples using the TGA and DSC instruments. The crude oils were mixed with different weight percentages (10%, 20%, and 30%) of water, ...
Numerical reservoir simulation of Alaşehir geothermal field
Aydın, Hakkı; Akın, Serhat (null; 2020-02-10)
Use of a comprehensive reservoir simulation is essential for an effective geothermal reservoir management. TOUGH2 has become a widely used simulator for this purpose. In this study, one of the most exploited geothermal fie...
Characterizing the declining CO2 emissions from Turkish geothermal power plants
Akın, Serhat; Örücü, Yasemin; Frıdrıksson, Thrainn (null; 2020-02-10)
Turkish geothermal fluids have substantially higher carbon dioxide content due to the unusual geologic setting of the geothermal fields in the country. Typical emission factors at power plant commissioning range from 1,000...
