Overview
The GN Z-ASFA Asphaltene Inhibitor Series is specifically designed for crude oil systems with high asphaltene and resin content. It is used to control precipitation, aggregation, and deposition of asphaltenes during production, transportation, and processing operations.
Through molecular adsorption, steric stabilization, and colloidal system regulation, the products effectively prevent asphaltene destabilization and precipitation from crude oil systems while dispersing and re-stabilizing already-formed aggregates.
The series is widely applied in high-asphaltene, high-aromatic, and complex crude oil systems and represents a critical chemical solution in oilfield flow assurance programs.
