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.

Wax deposition in horizontal wells Ozbayoglu, M.E.; Demiral, B.; Kök, Mustafa Verşan (2000-01-01) In this research, wax deposition in horizontal well bores was studied. In a horizontal well, the main mechanism for wax appearance is the pressure change rather than the temperature change. Six different thermodynamic models were improved for horizontal wells by adding a pressure function, and a computer program was developed to simulate the precipitation phenomena in horizontal wells. Solid-liquid equilibrium constants for each pseudo-component were calculated. Critical pressures and overall solid mole fac...
Combustion characteristics and kinetic analysis of Turkish crude oils and their SARA fractions by DSC Kök, Mustafa Verşan (Springer Science and Business Media LLC, 2013-10-01) In this study, two Turkish crude oils from southeastern part of Turkey and their saturate, aromatic, resin fractions were analyzed by differential scanning calorimetry (DSC). The experiments were performed at three different heating rates (5, 10, 15 A degrees C min(-1)) under air atmosphere. Two different reaction regions were observed from DSC curves due to the oxidative degradation of crude oil components. In the first reaction region, it was deduced that the free moisture, volatile hydrocarbons were evap...
Comparative methods in the determination of wax content and pour points of crude oils Kök, Mustafa Verşan; Claudy, P. (2007-12-01) In this research, differential scanning calorimetry (DSC) and gas chromatography is used to determine the wax content of fourteen crude oils of different sources. Different empirical equations were applied to compare the wax content of crude oils. For the fourteen crude oil samples with the wax content ranging from 7.5 to 43.8 mass%, it was observed that the results of empirical equations were in good agreement with those determined by DSC and GC. Accordingly, a correlation between ASTM pour point and the t...
Comparison of Wax Appearance Temperatures of Crude Oils by Differential Scanning Calorimetry, Thermomicroscopy and Viscometry Kök, Mustafa Verşan (1996-07-01) This paper presents the results of an experimental study of the determination of wax appearance temperatures (WAT) of 15 crude oils by differential scanning calorimetry (d.s.c.), thermomicroscopy and viscometry. Good agreement is obtained among the three techniques for crude oils having a significant precipitation rate. Considering the great diversity of crude oils, it is concluded that d.s.c. and thermomicroscopy should be used together for a better understanding of the determination of WAT of crude oils.
Pyrolysis and Combustion Studies of Fossil Fuels by Thermal Analysis Methods Review Kök, Mustafa Verşan (1995-02-01) Instances where differential scanning calorimetry, thermogravimetry and differential thermal analysis have been applied to study the pyrolysis and combustion behaviour of fossil fuels (peat, lignite, bituminous coals, anthracite, oil shales, crude oils, lignite-oil mixtures, etc.) are reviewed. The literature survey showed that thermal methods were important not only theoretically but also from a practical point of view.
