Quartz crystal characterization of fractions derived from pre-refined crude and/or cracked streams |
abstract |
Methods are provided for characterizing the stability of a distillate fraction using a quartz crystal microbalance apparatus, such as a distillate fraction derived at least in part from a pre-refined crude oil. A sample can be aged for an aging period in a quartz crystal microbalance apparatus, and a frequency value for the sample in the quartz crystal microbalance apparatus can be determined before and after the aging period to determine a frequency difference. This frequency difference can be correlated directly with the ability of a jet fuel fraction to satisfy a stability test standard, such as a jet fuel breakpoint stability. The methods can also include using a temperature profile during characterization that can reduce or minimize operator error during the characterization. |
