STABILIZATION OF ASPHALTENE DEPOSITION USING NEW DEEP EUTECTIC SOLVENTS

Abstract

Introduction. Currently, one of the most common problems in the field of oil production, processing, and transportation is the aggregation and precipitation of asphaltenes. Asphaltene deposits clog pipelines, pumps, separators, and other technological equipment, significantly reducing the efficiency of oil extraction. This situation leads to technical disruptions, decreased product quality, additional financial costs, and increased environmental risks. The purpose of the work: is to apply deep eutectic solvents as inhibitors of asphaltene precipitation in oil for stabilization purposes. Results and discussions: A deep eutectic solvent was synthesized, asphaltenes were extracted from oil from the Karazhanbas oil field, and a model oil was prepared. The effectiveness of using new green inhibitors for asphaltene precipitation in model oil was studied using UV spectroscopy. Conclusion: The research results showed that the synthesized deep eutectic solvent based on betaine performed well as an inhibitor and can be applied in the oil industry for enhancing oil recovery stabilization.
