The Improvement of Low Temperature Flow Characteristics of Waxy Crude Oil Using Multifunctional Polymeric Additives

摘要

In the present work, the influence of four polymeric flow improvers with different ranges of molecular weight on the viscosity and pour point of Indian waxy crude oil was evaluated. The additives were purified and characterized by FT-IR, ~1H-NMR, and ~(13)C-NMR spectroscopy. Determination of molecular weight was done by using gel permeation chromatography. Pour point depressant treatment was made on selected waxy oil, and the results indicate that the performance of flow improvers was dependent on the molecular weight, pendent alkyl chain of additive, and the type of crude oil.
