Abstract:During the production of crude oil, asphaltenes are prone
to precipitate
due to the changes of external conditions (temperature, pressure,
etc.). Therefore, a series of research studies were designed to investigate
the effect of temperature on asphaltene precipitation for two Xinjiang
crude oils (S1, S2) so as to reveal the mechanism of asphaltene dissolution.
First, the changes of asphaltene precipitation were intuitively observed
by using a microscope. The results demonstrated that the asphaltene
solubility … Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
