Results of inhibitor performance at slug flow in a 101.6 mm inner diameter horizontal pipeline. Electrochemical Impedance Spectroscopy (EIS) and scanning electrom microscope (SEM) techniques are used to reveal that the strong bubble impact, high shear stress and turbulent intensity are the reasons for a poor performance of inhibitor.
This presentation summarizes the development and expansion of a comprehensive information system for corrosion of metals and alloys in high temperature gases. New insights in analysis of thermochemical data for the Fe-Ni-Cr-Co-C-O-S-N system are being compiled. Corrosion mechanisms emphasized are oxidation, sulfidation, sulfidation/oxidation, and carburization.
