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 temperature at which 2 mass% of wax has precipitated out from crude oil is developed.

DSC and rheometry investigations of crude oils Kök, Mustafa Verşan; Claudy, Pierre (1999-01-01) Thermal characteristics and rheological behaviour of eight crude oils covered a wide range of fluid composition and properties were studied by differential scanning calorimeter (DSC) and viscometry. Wax appearance temperatures (WAT) of crude oils were determined by DSC and viscometry. Good agreement is obtained between the results. The dynamic viscosity in the Newtonian temperature range of the crude oils (above 30 degrees C) generally obeyed a simple first-order Arrhenius type of temperature dependence. Ac...
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.
Thermal characteristics of crude oils treated with rheology modifiers Kök, Mustafa Verşan; Cloudy, P.; Martin, D.; Garcin, M.; Volle, J.L. (1997-12-01) Thermal characteristics of eight crude oils and their treatment with additives were studied by differential scanning calorimetry (DSC), thermomicroscopy, viscometer and pour point tester. Different additives were found as more effective for different type of crude oils depending on the wax content. Crude oils showed a reduced pour point after treatment with additives. Effects of different additives were also discussed by analysing the DSC curves and thermomicroscopy result.
Thermal behavior and kinetics of crude oils at low heating rates by differential scanning calorimeter Kök, Mustafa Verşan (2012-04-01) The objective of this research was to investigate thermal behavior and kinetics of different origin crude oils in limestone matrix by differential scanning calorimeter (DSC) at low heating rates. In DSC experiments, three distinct reaction regions were identified in all of the crude oil + limestone mixtures known as low temperature oxidation (LTO), fuel deposition (FD) and high temperature oxidation (HTO) respectively. Kinetic analysis of the crude oil samples was determined by different models known as AST...
Evaluation of adsorbents with passive sampling and their analytical methods to determine volatile organic compounds emitted from vehicular exhaust CİVAN, MİHRİBAN; Tuncel, Süleyman Gürdal (2012-04-01) In order to accurate and precise determination of Volatile Organic Compounds (VOCs) from vehicular emissions were developed method including a) adsorption of VOCs on different adsorbents followed by thermal desorption and gas chromatography (GC) with flame ionization detector (FID) quantification, b) validation of the sampling and analytical method. The adsorption efficiency of Tenax and Chromosorb 106 adsorbents were eveluated for 104 VOCs to select of adequate sorbent for passive sampling. Since most of t...
