Methods for determining asphaltene stability in crude oils

Crude oil is extracted from the bedrock before being processed in several stages, removing natural contaminants and undesirable hydrocarbons. This separation process produces mineral oil, which can in turn be denoted as paraffinic, naphthenic or aromatic. The differences between these different types of oils are not clear-cut, but mainly depend on the predominant hydrocarbon types in the oil. Paraffinic oil, for example, contains primarily higher alkanes, whereas naphtheni… WitrynaThe presence of naphthenic base oil and/or vegetable oil in paraffin-based lubricant oils such as automotive engine lubricant oils can severely compromise the lubricant … Witryna1 wrz 2024 · The acidic ingredients in crude oil are usually in the form of complex naphthenic acids.
