Asphaltenes are a components of crude oil defined as a solubility class, i.e. , as a component of crude oil insoluble in n-pentane (C5 asphaltenes) or n-heptane (C7 asphaltenes) but soluble in aromatic solvents such as toluene, and are complex, polyaromatic, macrocyclic structures with an overall varied composition Asphaltene deposition, remediation, and inhibition are important considerations for flow assurance in upstream processes, but methodologies to assess performance for cleaning purposes can provide variable results. We report on the development of a dispersant additive for aromatic solvent systems using a QCMB technique for evaluating the cleaning of a deposit. Further, we report the performance of the additive in a case study and, hence, the utility of the technique to provide an assessment for potential field use.
