Heavy crude oil viscosity reducer

摘要

A viscosity reducer based on vegetable extracts of natural origin is disclosed. The vegetable extracts include a mixture of phosphoglycerides and vegetable oils. A method of reducing the viscosity in heavy and extra heavy crude oil using the viscosity reducer is also disclosed. No aromatic base solvents are needed. A reduction in diluent usage is achieved using the viscosity reducer based on vegetable extracts. The viscosity reducer composition includes a mixture of phosphoglycerides, vegetable oil, non-aromatic solvent, polycyclic aromatic hydrocarbon and stabilizer.

1. A method of reducing the viscosity of hydrocarbon fluid comprising treating the hydrocarbon fluid with a viscosity reducer composition by injecting the viscosity reducer composition into a pipeline for transport, the viscosity reducer composition consisting essentially of phosphoglyceride, vegetable oil, non-aromatic solvent, polycyclic aromatic hydrocarbon and stabilizer, wherein the hydrocarbon fluid is heavy and/or extra heavy crude oil having an API in the range of from about 7 to about 22, and further wherein the viscosity of the hydrocarbon fluid is reduced by an amount in the range of from about 10% to about 60%.
