  • Patent number: 7437247
    Abstract: The invention relates to a method of estimating the flow restart conditions of a paraffinic hydrocarbon in a pipe, wherein the following stages are carried out: selecting a theological model, determining the temperature and shear stress fields in the steady hydrocarbon flow, evaluating the conductive thermal exchanges during circulation standstill phases, from the steady flow temperatures and the standstill time taken into account, selecting various sections of the pipe and recording the thermomechanical scenarios undergone by the hydrocarbon in these sections, experimentally measuring the rheological parameters of the model on a sample of the hydrocarbon, according to each one of said scenarios, and taking into account these experimental measurements to evaluate the value of the pressure that restarts circulation of the paraffinic hydrocarbon in the pipe.
