Characterization of compositions in crude oil and the effect of inhibitor on the crystallization of paraffin

Flowability is one of the important characters of a crude oil in pipelines. The viscosity of one crude oil is affected by many factors (e.g., temperature, water cut, composition distribution, paraffin deposition, etc.). In this study, IR, thermogravimetry analysis (TGA) and UV measurement are employed to characterize the composition of the crude oil (HN-1) provided by Henan Oilfield. The paraffin morphology analysis is employed to rate the property of a mixture of paraffin inhibitors and analysis the mechanism of the paraffin inhibition. (paper)
