These high-molecular-weight, polar compounds tend to aggregate, leading to increased viscosity, equipment fouling, catalyst deactivation, and flow assurance challenges. Their chemical complexity and strong intermolecular interactions make them particularly resistant to conventional separation techniques. The article reviews state-of-the-art neutralization strategies, including chemical dispersants, surface-active agents, and nanomaterial-based solutions. Experimental insights into additive performance, interaction kinetics, and process optimization are presented to evaluate their practical applicability. Keywords: Asphaltenes, resins, crude oil refining, flow assurance, catalyst deactivation, chemical dispersants, process optimization.
