Abstract:
ASTM D5623 measures sulfur compounds in light petroleum liquids by a gas chromatography and sulfur selective detector up to 230°C. However, many sulfur species in these boiling ranges are not identified and classified as “unknowns.” Furthermore, sulfur species beyond 230°C are sometimes needed for sour crudes, catalyst performance and tracking environmental compliance. To expand ASTM D5623, overcoming the chromatographic challenges of separating these heavier sulfur compounds is a challenge.
In an attempt to expand ASTM D5623, many exotic sulfur species are identified along with analyzing various “out of scope” heavier boiling range hydrocarbons. This abstract will discuss what is Sulfur Chemiluminescence and the findings from this study.
