Abstract:
The purpose is to study the internal corrosion rate through the analysis and Simulation of pipeline routing factors in multiphase pipelines. Methods theoretical analysis and numerical simulation are adopted respectively. Multiphase flow simulation software OLGA is used to collect and analyze pipeline related operational parameters, routing parameters and transport medium components. A corrosion prediction model for oil-gas mixing pipelines in OLGA is selected. Results the influence of pipeline pressure, temperature, fluid velocity, liquid holdup and flow pattern distribution on internal corrosion rate was analyzed. After setting up the model and setting up the model parameters, the simulation results are analyzed and the results of the corrosion rate in the pipeline are predicted. For the study of single factors on mixed transportation pipeline corrosion rate, simplify the pipeline model, retaining only the pipeline uphill and downhill two pipe sections, by modifying the parameters of pipeline parameters and medium, effect of single factor on mixed transportation pipeline internal corrosion. Conclusion pipeline routing has a great influence on the internal corrosion rate of mixed pipeline, but even in the uphill and downhill stage of the mixed pipeline, the same factor also has a different impact on the internal corrosion rate.
