2. An Experimental Study on Evaluation of Factors Influencing the Viscosity and Viscoelastic Properties of Waxy Crude Oil

Yavar Karimi; Ali Reza Solaimany Nazar

Volume 9, Issue 1 , Winter 2020, , Pages 1-15

  The influences of several operating factors on the viscosity of the Isfahan refinery waxy crude oil sample are studied through conducting some rheological shear rotational tests. The Taguchi design method is adopted to determine the impact of factors such as shear rate, temperature, cooling rate, wax ...  Read More
