Resumo: | |||||||||||||
Wax deposition is defined as one of the major problems in oil production and
transportation pipelines projects. The prediction of the deposition can lead include
thermal insulation along the line, installation of launchers and receivers of pigs for
cleaning the pipes, addition of deposition inhibitors, etc. Due to these major
technical and financial impacts, the ability to generate accurate predictions of the
deposition process is crucial in the oil industry. However, there is great divergence
in the scientific community regarding the dominant mechanisms for predicting the
deposition phenomenon.
In the present study, the deposition phenomenon was analyzed from
numerical simulations based on the heat transfer mechanism. The fluid
composition properties were adopted as pre-processing step based on the
composition and pressure and temperature working ranges; and inserted in the
simulation through thermodynamic tables.
Different configurations available in the literature were selected to evaluate
the modeling. The predictions obtained with models available in the literature were
analyzed, aiming to evaluate the model developed in the present study in relation
to other models (purely thermodynamic, being the deposit determined considering
solid saturation of 2 percent, or considering mass diffusion).
The results obtained with the different models were qualitatively similar and
the selection of the best model is still open, as better experimental data and better
characterized fluids still need to be available.
