Molecular Interaction Study on a New Application of Ionic Liquids as Dissolver toward Carbonate Scale

Latest advances of ionic liquids (ILs) have allowed to a new application on the dissolution calcium carbonate (CaCO3) scales where CaCO3 scale deposition seriously severe threat in petroleum field. In this study, molecular interaction between and ILs n-pyridinium chloride [NPy][Cl] was studied experimentally order get better understanding during scale. NMR FTIR spectroscopy used study solution process. To further evaluate result, simulation using Gaussian software utilized predict detail [Npy][Cl] CaCO3. The finding from showed that metal complex formed via ligand after Based findings, it can be clinched has potential as dissolver oilfield, especially dissolving scales.
