US Patent No: 9784414

Drag reduction of asphaltenic crude oils

---

Abstract

---

A process for preparing a drag reducing polymer which is to be added to a liquid hydrocarbon. The liquid hydrocarbon has an asphaltene content of at least about 3 weight percent and an API gravity of less than about 26°. The drag reducing polymer can comprise the residues of a monomer having at least one heteroatom. Treatment of the liquid hydrocarbon with the drag reducing polymer allows a reduction in pressure drop associated with turbulent flow of the liquid hydrocarbon through a conduit.
