RESUMO
This work studies the flow of an oil-paraffin mixture through a tube, simulating the conditions of petroleum extraction in deep waters.An apparatus was built allowing for pressure and temperature control at the inlet of the test section. Experiments have been performed keeping constant either the pressure or the flow rate, aiming at understanding the phenomenon of tube obstruction. The analysis of results for both pressure drop measurements and rheological measurements of the deposited material showed that, under certain conditions, it is possible the formation of a soft and easy-to-remove structured deposit, which is washed away by the flow itself, inhibiting in this manner deposition by molecular diffusion.
