The study of group hydrocarbon content of oil from Garbi Absheron field

With the increase of production and processing of the heavy oils, an issue of the complex research of their group hydrocarbon content and properties occurs. An adsorption method of separation of native oil from Garbi Absheron field with KSM brand silicagel was applied to study the group hydrocarbon content. Methane-naphthene and separate groups of aromatic hydrocarbons, asphaltene-resin compounds have been obtained. It was established that this oil consists of 42.40 % saturated (methane-naphtene), 44.46 % aromatic hydrocarbons and 13.14 % asphaltene-resin compounds. The structural group content of the fractions obtained has been studied via the spectral (IR and UV) methods. Due to the fact that by its physico-chemical properties, commercial quality and fractional analysis, this oil is close to the other Azerbaijani heavy oils, their combined transportation and refining is recommended.
