abstract: This is the final report on the problem of wax deposition in oil pipelines, brought to ESGI56 by Norsk Hydro.


problem_statement: In oil extraction from the North Sea, one problem is the build up of wax in undersea pipelines. When the oil temperature is 60–70°C, all the wax is dissolved, but as the temperature drops below 35–40°C, wax solidifies onto the walls of the pipe, restricting the flow. Norsk Hydro wish to understand the physical processes involved, and to understand some experimental results on wax deposition. The Study Group showed that modelling the problem using kinetic undercooling and shear-induced diffusion gave results in broad agreement with the experiments.
