Studies on the effect of sulfonate based ionic liquids on asphaltenes
Deposition of asphaltenes precipitates potentially clog the oil well, block the production pipelines and causes catalyst deactivation during refining of the crude. Hence, remediation of the asphaltenes deposition is warranted. Different types of chemicals have been investigated and applied to act as...
