Experimental Investigations of Rheological Properties of Nile Blend Waxy Crude

Abstract

In this paper, laboratory work has been carried out using samples of Sudanese crude (Nile blend) in order to describe its rheological behavior at different flow and thermal conditions, and hence, identifying the temperature dependency of these properties. The rheological properties of Nile blend have been measured using a reliable viscometer connected to a water bath to allow simulating of the pipeline flow temperature. The rheological properties of Nile blend have been correlated with temperatures at different heating treatment conditions. The developed correlations can be utilized in prediction of pressure profiles along Higlig-PortSudan pipeline during its operation condition. The outcome of this paper is useful in performing hydraulic calculations of Higlieg-PortSudan pipeline under non-isothermal operation.
