Abstract
Petroleum is a naturally occurring complex mixture containing predominantly hydrocarbons and a significant quantity of nitrogen and sulfur. Currently, no methods are available for the simultaneous determination of these components along with their boiling point distributions. Hence, a new analytical technique was developed for the quantification of petroleum components using “high temperature CNS-simulated distillation” (HT-CNS SimDis) equipped with flame ionization and chemiluminescence detectors. The method has the advantages of reporting percentage yield, percentage recovery, and total component determinations along with their boiling point distributions. Total sulfur and total nitrogen contents obtained by this technique are compared with that of the ASTM method. Presently this method is being applied for heavy petroleum fractions such as VGO samples. A new reference standard, “VGO NS reference”, was developed as a secondary standard for the quantification of sulfur and nitrogen. Requirement for less ...
