Comparison of the Acids determined in Biodegraded and Non-degraded Oils

Abstract

In this project the main emphasis has been placed on comparing the acids contained in the non-degraded Tyrihans oil with that of a biodegraded Heidrun oil. These two oils are believed to be sourced from the same Spekk source rock. Before one can start comparing oils from different areas and with widely differing source rocks, it seemed necessary to look for evidence as to whether the source rock does affect the suite of acids occurring in oils. The acids determined in the Heidrun and Tyrihans oils are compared with the acids reported to be in naphthenic acid fractions obtained from refineries which had processed a different set of oils.
