13. NUMERICAL SIMULATION OF WAX DEPOSITION IN PETROLEUM LINES: ASSESSEMENT OF MOLECULAR DIFFUSION AND BROWNIAN DIFFUSION MECHANISMS / SIMULAÇÃO NUMÉRICA DA DEPOSIÇÃO DE PARAFINA EM DUTOS DE PETRÓLEO: AVALIAÇÃO DOS MECANISMOS DE DIFUSÃO MOLECULAR E DIFUSÃO BROWNIANA
Wax deposition is one of the major critical operational problems in crude oil pipelines operating in cold environments. Therefore, accurate prediction of the wax deposition is crucial for the efficient design of subsea lines. Unfortunately, wax deposition is a complex process for which the mechanisms are still not fully understood. Aiming at the identificati
