Hydraulic behaviour of Higleig-Portsudan pipeline at operation and shutdown conditions

Experimental measurements were carried out to correlate rheological properties of nile blend with temperature within temperature ranges at which nile blend exhibits newtonian,non-newtonian,and solidification behaviours. the developed correlations were used to describe the hydraulic conditions within each kilometre length of the pipeline during operation and the pressure difference required for restarting and flushing every kilometre length of the pipeline after specified shutdown time. pressure losses within every kilometre length of the pipeline at different flow behaviours during the pipeline operation have been studied and analysed. the required restarting pressure of every kilometre length has also been studied taking into consideration the possibility of crude solidification. the pressure head transverse between every two pump stations and the effect of flow rate on the pipeline overall pressure losses during operating conditions were studied. these results have been obtained using numerical software developed by the author. © school of engineering,taylor's university.
