Abstract

In this work, a series of hydroxylmethyl triamide (HMTA) was synthesized from vegetable oil, diethylenetriamine were and hexamethylenetetramine, which was evaluated as a crude oil flow improver. The results showed that HMTA has a good viscosity reduction effect on the crude oil from Yanchang Oilfield, with the highest viscosity reduction rate of 89%. The highest pour point reduction depression was achieved as 7.4°C. Differential scanning calorimetry and paraffin crystal morphology characterization were conducted on the crude oil to elucidate the mechanism of viscosity reduction and pour point depression.

Keywords:

vegetable oil hydroxylmethyl triamide crude oil flow improver paraffin
