Research on the Pre-film Progress of Inhibitor in Nature Gas Pipeline

Natural gas contains a complex mixture of H2S, CO2, water, etc. which seriously affects the normal production of natural gas pipeline. Inhibitor can significantly inhibit the corrosion rate. Base on the atomized flow of the liquid theory, this paper studied the atomization process, atomization concentration and mechanism of protection of the inhibitor in pipelines, then calculated the time for pre-film, the amount of inhibitor and the protection distance of inhibitor. Finally, a pipeline of a numerical example had been shown, which had practical significance for industrial production.
