Asphaltene Inhibitor Dispersant
Asphaltene inhibitor is an aromatic resin-based dispersant that prevents asphaltene aggregation, flocculation, and deposition in production tubing, surface facilities, and crude oil pipelines. It stabilizes asphaltene particles in the crude oil matrix by steric and electrostatic mechanisms, significantly reducing plugging incidents. Effective at dosages of 50–500 ppm and compatible with oil-based and mixed injection systems.
