Özet

In this research, wax appearance temperatures (WAT) of eight different crude oils from south-eastern region of Turkey were determined by differential scanning calorimetry. The experiments were performed at a heating/ cooling-rate of 2 degrees C/min from 60 to -20 degrees C It was observed that the wax appearance temperature of different origin crude oils was varied between 14.2 and 37.8 degrees C depending on the API gravity and wax content. It was also observed that the crude oils have enthalpy of precipitation ranging from -3.42 to + 6.39 mW and melting enthalpy from - 2.5 to + 7.46 mW, respectively.
