Preparation of Crude Oil Flow Improver from Vegetable Oil and the Performance Evaluation

Article Preview

Abstract:

In this work, a series of hydroxylmethyl pentamine (HMPA) was synthesized from vegetable oil, tetraethylene pentamine and hexamethylenetetramine, which was evaluated as a crude oil flow improver. The results showed that HMPAs have good viscosity reduction effect on the crude oil from Yanchang Oilfield, with the highest viscosity reduction rate of 93%. The highest pour point reduction depression was achieved as 5.4°C. Paraffin crystal morphology characterization was conducted on the crude oil to elucidate the mechanism of viscosity reduction and pour point depression.
