Methyl Mannose Polysaccharides as Naphthenic Acid Extraction Agents

With this project, we propose a new approach for removing Naphthenic Acids (NAs) from aqueous solutions (tailing ponds) using naturally occurring carbohydrates termed methyl mannose polysaccharides (MMPs), or their fragments. Since MMPs have a very high affinity for lipids, we hypothesize that these carbohydrates could be used to remediate water contaminated with hydrophobic NAs.
