Asphaltene precipitation is a challenging problem for the petroleum industry. Changes in pressure, temperature, and composition are key factors that influence asphaltene stability in crude oils. We have previously shown that the time required to precipitate asphaltenes can actually vary from a few minutes to several months, depending on the precipitant concentration used and that no single concentration can be identified as the critical precipitant concentration for asphaltene precipitation. Both upstream and downstream processes involve temperature variations, which can cause the precipitation of asphaltenes and can lead to deposition and fouling problems during the production, transportation, and processing of crude oils. In the present work, we extend the findings of the previous research to incorporate the effect of temperature on the precipitation kinetics of asphaltenes. The effect of temperature on asphaltene stability can be complex and various competing effects can be identified. We demonstrate that at higher temperatures the precipitation onset time for asphaltenes is shorter and their solubility is higher. We also present a hypothesis to explain these results and demonstrate that the viscosity difference resulting from a change in temperature is the key parameter in the aggregation of asphaltenes and controls the onset time for precipitation. We also consider the effect of expansion of hydrocarbons, oxidation of crude oil, and the loss of light hydrocarbons due to evaporation, all of which are possible when temperature is increased. This research provides a unified approach to understand the variety of factors that change as a result of temperature variation and evaluates their individual contributions to changes in asphaltene precipitation kinetics and their solubility.
