One of the main problems encountered in oil production in deepwaters is the wax deposition in production and transportation lines. As the oil flows in the pipelines, it loses heat to the colder outside environment, reducing its solubility to heavy hydrocarbons, and potentially leading to deposition at the pipe walls. Wax deposition may cause loss of production and even the complete blockage of the line. The ability to predict the spatial and temporal variation of the deposits is relevant to the design and operation of subsea lines. An updated literature review revealed that the mechanisms responsible for wax deposition are still not fully understood. The present work is part of an ongoing research project aimed at studying the mechanisms responsible for wax deposition in pipelines. Laboratory experiments were conducted for turbulent flow of wax and querosene solutions through a specially designed test section that allowed for optical acces. An optical microscope was employed for measuring the wax deposit thicknesses which were shown to decrease with increasing Reynolds number. The deposits measured in the turbulent regime were smaller than those for the laminar regime. The good quality of the visualizations obtained allowed the observation of wax deposit removal by shear effects. The experimental results obtained are available for comparison with numerical solutions, what can contribute to the study of the basic mechanisms responsible for wax deposition.
