Blending
of different crude oils is currently carried out in the
petroleum industry. However, under certain process conditions, i.e.,
pressure, temperature, flow regime, composition, etc., asphaltene
precipitation and plugging of pipelines and process equipment commonly
occur, which cause production shutdowns; therefore, special cleaning
programs need to be developed. To avoid these problems, it is first
necessary to evaluate the compatibility of crude oil blends through
a study of asphaltene stability. Most of the available tests are focused
on analyzing crude oils under standard conditions, i.e., temperature,
pressure, solvent/oil ratio, or static testing; however, studies at
dynamic conditions are scarce. Dynamic testing is a more representative
approach to correlate experimental information with data of transportation
of crude oils, where pressure, temperature, and flow regimes influence
crude oil stability and compatibility. In this work, the literature
reports of dynamic experimental setups are summarized and analyzed,
whereby asphaltene deposition and precipitation are typically studied.
