Kilpatrick Affiliation: North Carolina State University This grant is awarded through the Separations and Purification Program sub-element of the Interfacial, Transport and Separations Program of the Chemical and Transport Systems Division. The principal investigator is Dr. Peter Kilpatrick at North Carolina State University. The research involves fundamental studies on the emulsion and foam formation characteristics of asphaltenes commonly found in the petroleum industry. Such asphaltene based emulsions are made up of viscoelastic films formed by crosslinking of primary aggregates. These crosslinked flocculates are environmentally deleterious as they may pose health hazards as endocrine disruptors. Additionally, they form waxy dispersions that tend to plug exploration and transmission pipelines. The objective of the work is to elucidate the mechanisms of formation, the stability aspects and rheological properties of these emulsions. Such fundamental studies will open the way to mitigate the formation of these emulsions.
