An Investigation of the Effect of Asphaltene Polydispersity on Asphaltene Precipitation and Deposition Tendencies [PDF]
, 2022 It is well-known that asphaltenes are a polydisperse fraction present in crude oil with a broad distribution of sizes and molecular characteristics. However, in practice, asphaltenes are often treated both in the laboratory and in modeling work as a ...
