Precipitation of colloidal asphaltenes, the most polar and heaviest component of crude oil, manifests itself in almost all facets of production, transportation and processing of crude oil. Root causes are generally pressure drops, pH changes and crude mixing.
Asphaltene precipitation deep inside the reservoir, in pipelines or onto safety equipment can cause blockages and severe emulsion formation resulting in reservoir damage, loss of crude oil recovery and escalating costs.
To combat this problem, Croda has developed an innovative range of oil soluble asphaltene dispersants under the Hypermer™ brand name. Advantages of this pioneering technology include:
- Inhibition of asphaltene agglomeration and precipitation
- Solubilisation of asphaltene colloids into the oil phase
- Significant reduction in fouling
- Improved dehydration
- Reduction in severe emulsion formation
- Increased flow assurance
The superior performance of these products is due to targeted molecular design looking at the interaction between solid and surfactant molecules.
