Flowing fluid loop cell (FFLC) system design and FFLC-based corrosion testing under acid conditions Conference Paper uri icon


  • 2016 by NACE International. The corrosion testing system is scientifically and practically critical for corrosion testing and simulations. The main content of this work include the construction of the flowing fluid cell loop (FFL) system, as well as FFCL-based corrosion/anticorrosion tests under simulated acid conditions. Two parts will be reported: in the first part, the flow loop design was introduced in detail. The finished flow loop met the requirements of producing turbulent fluid flow and working at acid conditions. In the second part, the corrosion process of carbon steel specimens at different flowing conditions were studied. The corrosion inhibition efficiency (Eff) of selected chemical formulations were studied. Electrochemical Impedance Spectroscopy (EIS) and Linear Polarization Resistance (LPR) were used as prime techniques to quantify and characterize the corrosion behaviors of carbon steel specimen. Charge transfer resistance and polarization resistance were obtained from the fitting of EIS and LPR results. The Eff vs. Reynolds number (Re) plots for the specimen located in the chamber and in loop branch were provided.
