Asphaltene Behaviors and Models

One of the challenges for a feasible NAE process is that the final extracted bitumen product is free of water and mineral/clay solids so that it can be used as refinery feed.


This project is a systematic investigation of various asphaltene behaviors and models by combining quantitative intermolecular and surface force measurements and molecular dynamics simulations in NAE processes (e.g., nonaqueous extraction, solvent recovery and product cleaning) and in partially upgraded bitumen.
