← ScienceWhich outcome results when cooling high-viscosity crude oil?
A)Increased turbulence within transport pipelines
B)Formation of paraffin wax crystals✓
C)Reduced adhesion to pipeline surfaces
D)Decreased pump energy requirements
💡 Explanation
Wax crystallization increases as temperature decreases because solubility decreases and therefore the waxy components solidify. Since this occurs because viscosity decreases at warmer temperature that keeps it in suspension rather than other effects.
