Predicting the Physical Property of Asphaltene Molecule using Fuzzy System
Abstract: Asphaltenes — the heaviest and most aromatic compounds of crude oil— have a strong tendency to aggregate in solution to form complex colloidal structures. They generally impede producing, transporting and refining of crude oil resources. An indepth knowledge of the physical behavior of asphaltenes is needed to mitigate these effects. Predicting the physical behavior of asphaltene such as density is complex and nonlinear as it is a complex molecular mixture …
