Waxy crude oils represent a significant amount of the petroleum reserves and productions worldwide, and the pipeline transportation of waxy crude oils is an 

In order to optimize profitability in the handling of waxy crude oil pipelines, an literatures discuss methods of handling the transportation of waxy crude oils in. 1 Feb 1995 In evaluations of the wax potential of a crude, the climate of the area Petroleum -- Drilling & Production; 022000 -- Petroleum-- Transport,  7 May 2018 crude oil and to evaluate the suitable inhibitor for the waxy crude oil that provides the transportation in the hydrocarbon pipeline systems. vessel surfaces. COPI™ provides important benefits in: • Crude oil production. • Crude oil transportation. • Storage. Wax crystallites can start forming in crude oil. 24 Jan 2019 transportation of these waxy crude oils in the pipelines contribute to several issues, such as the flowability reduction, excessive pumping cost, 

As with transportation length enlargement and shut-down time prolongation, the transfer stations that have to be used before PPD is adopted also can be eliminated and the transfer system becomes simpler and safer for buried flow-line to transport waxy crude oil.

In the working range used, the flow of waxy crude oil proved to be dependent on the flow rate, temperature and interaction between combinations of the flow rate and water cut. The variable that was the most significant for the waxy crude oil was the temperature, which was inversely proportional to the pressure gain.

Transportation of waxy crude oil has received significant attentions as its pour point temperature is well above the seabed temperature at production fields. There have been different techniques used to alleviate flow problems prior to pumping . Wax inhibitor, use of chemicals, pour point depressant, catalytic treatment, thermal treatment and wax control polymers were among few mechanisms used earlier. TRANSPORTATION OF WAXY CRUDE OILS 1. Select pumps to allow a parallel/series arrangement, which could transport at slower. 2. Use of separate low flow, high head pumps for restarting. 3. Side traps at frequent intervals to allow short sections to be started separately. 4. Reverse pumping to Crude Oil Transportation: Nigerian Niger Delta Waxy Crude Elijah Taiwo 1, John Otolorin 1 and Tinuade Afolabi 2 1Obafemi Awolowo University, Ile-Ife, De partment of Chemical Engineering, 2Ladoke Akintola University of Technology, Ogbomoso, Department of Chemical Engineering, Nigeria 1. Introduction DEFINITION OF A WAXY CRUDE A waxy crude is defined as a crude oil having a high pour point and low API gravity, and often containing paraffin wax (alkanes). A waxy crude is distinguished by the fact that it exhibits non-Newtonian viscosity behaviour at temperatures below about 20F above the pour point.
