Transcripción del resumen del autor. Batch corrosion inhibitors are used widely for the corrosion control of production wells and pipelines in the oil and gas industry. Rules of thumb that incorporate film thickness, contact time, and surface area are still commonly used to calculate the volume of batch inhibitor required for pipeline applications. Measuring the actual thickness of the inhibitor film on the metal and the impact of different variables on the film (e.g., inhibitor type, contact time, diluent type, dilution ratio, shear stress) offer the potential to provide a better understanding for optimizing the application procedure and required batch frequency. Optical profiling (or white-light interferometry) has long been a standard technique for noncontact, three-dimensional (3-D) measurement of surface topography. This method now has been extended to thickness measurements of semitransparent batch inhibitor films. In this paper, the impact of several variables (i.e., inhibitor type, contact time, diluent ratio, shear stress) on batch inhibitor films was studied using an optical profiler. This knowledge can be used to advance batch inhibitor application techniques and to optimize batch treatment programs for improved cost effectiveness and safety.
