Geothermal technology has gained wide attention as a new source of renewable energy but its optimum utilization is limited by accelerated corrosion. Solutions for this problem are often reactive such as regular preventive maintenance and replacement for corrosion affected components. A proactive way to solve this problem is by utilizing anti-corrosion polymers designed for geothermal brine chemistry. In this study, two different types of polymer application, an inhibitor and a coating, were evaluated for the corrosion protection of carbon steel in acidic geothermal brine. Polyvinylpyrrolidone(PVP) was used as a corrosion inhibitor while a nanocomposite composed of Polybenzoxazine, rubber and montmorillonite (PBZ-R-MMT) was synthesized for coating application. Various characterization techniques such as Scanning Electron Microscopy (SEM), X-ray Photoelectron Spectroscopy(XPS),Fourier Transform-Infrared ( FT-IR), X-ray Diffraction(XRD), Thermal Gravimetric Anaysis(TGA), and Differential Scanning Calorimetry(DSC) were done to determine the applicability and effect of these polymers to carbon steel immersed in simulated acidic geothermal brine. The anti-corrosion properties of both the inhibitor and the coating were tested further using electrochemical techniques.
