Asphaltene Removal – The Effect of Ionic Liquid to Asphaltene Characteristics

Crude oil composes of asphaltene, along with saturates, aromatics and resins (SARA) compound. Changes of temperature and pressure during oil production lead to the precipitation, flocculation and aggregation of asphaltene. This condition has caused many problems faced by the oil and gas industry,...
