A STUDY ON THE SUITABLE TECHNIQUES FOR IMPROVING THE FLOW PROPERTIES OF THE EGYPTIAN WAXY CRUDE OILS

In the present paper, three different techniques were used for improving the flow properties of three Egyptian waxy crude oils (M-96, GPY-3 and Khalda). These techniques are: dilution, heating and chemical treatment. The improvement efficiency for each technique was investigated by measuring the rheological properties and the pour point as well. Also, the eff ect of each improvement technique on the power requirement was studied through calculation of the reduction in the pipeline pressure loss. The studied techniques have shown promising results in improving the flow properties of the tested crudes. However, the most suitable technique for a specific crude should be decided in the light of the technical features studied in the present paper in addition to an economical study which should be performed on each case individually.
