Abstract
The physiochemical characteristics of the crude and deposited wax are two main issues associated to the flow assurance. They can provide useful estimates of the parameters and behavior required for operational engineering process developments and/or physical modifications to the processing of crude oils where the main objectives are to reduce costs of production and transportation. This study will attempt to determine and explain the new and effective way of eliminating paraffin depositions by utilizing a novel polymer which is called Ethylene–TetraFluoroEthylene (ETFE) with IUPAC name poly(ethylene-co-tetrafluoroethylene). Furthermore, this paper compares the known characteristics of three types of pipes—ETFE internal plastic pipe coating and rigid PVC plastic pipe coating and steel pipe. The paraffin deposition decreases as the effect of temperature increases from 5 to 25 °C and the flow rate increases from laminar to turbulent. The deposition reaches its peak at a fluid velocity value around 2.4 ft/s. The surface roughness of the three pipes steel, rigid PVC, and ETFE plastic pipe coated on paraffin deposition was evaluated. The ETFE plastic pipe with the least roughness recorded an appreciably good deposition (15 g/4 h) than the other two pipes. This study results show that ETFE internal plastic pipe coating is the most appropriate solution for paraffin deposition in the pipelines.
