  • Micro-hydrocarbon analysis
    Publication number: 20070114377
    Abstract: The present invention is a method to determine the composition of a hydrocarbon feedstream from a small sample of hydrocarbons including the steps analyzing the sample with a combination of chromatograph and mass spectrometer, and reconciling output from step a) with other analytical measurements to determine to determine the composition of the hydrocarbon feedstream.
    Type: Application

  • Measurement of distributed total acid numbers by electrospray mass spectrometry
    Publication number: 20070037288
    Abstract: The present invention is a method to determine the TAN and TAN as a function of boiling point for a hydrocarbon feedstream using an electrospray ionization mass spectrometer (ESI-MS). The steps of the method include determining the signal as a function of mass from the ESI-MS while minimizing the formation of oligomers and fragmentation of the molecular species in the feedstream and then determining the TAN from the signals. The TAN is also determined as a function of boiling point.

  • Method for determining the source of fouling in thermal conversion process units
    Publication number: 20050040076
    Abstract: The present invention relates to a method for determining the source of fouling in petroleum thermal conversion process units. More particularly, the invention distinguishes whether fouling occurs due to feed entrainment of small feed droplets or vapor phase condensation.
