Arterial blockage in the petroleum industry is mostly due to the deposition of heavy organics like wax from petroleum fluids. Wax is an undesirable constituent in crude oil due to high pour points and high viscosity index. De-waxing operation is broadly classified into two types namely: one with the use of solvents and other without solvents. In this work, xylene, n-hexane, kerosene and triethanolamine (TEA) were used for de-waxing operation. Different percentages of these solvents were added to the crude oil sample and their effect on the crude oil flow properties was evaluated. All these solvents evaluated improved the flow property of crude oil. Kerosene and triethanolamine (TEA) blends was more effective than the other solvents.
