This paper presents an experimental investigation on the application of silica nanoparticles as corrosion inhibitor in saline solutions that are relevant to oil and gas production systems. The gravimetric (weight loss) method was used to analyse the corrosion loss in mild steel exposed to different salinity brines in the absence and presence of nanoparticles for a period of 360 h. The results of the study showed that the solution salinity, concentration of nanoparticles and the duration of exposure influenced the corrosion process of mild steel. The use of low concentration (1 g/L) of nanoparticles in non-saline solution was found to be more efficient in corrosion inhibition than in saline solutions of different salt concentrations. The use of high concentration (5 g/L) of nanoparticles was however more efficient in saline solutions up to 3.2 g/L but at very high salinity level (32 g/L), slight reduction in its efficiency was observed. Lower efficiency of high concentration nanoparticles was also observed in non-saline solution. The novel potential of using silica nanoparticles as corrosion inhibitor in saline environments investigated in this study has unveiled the possibility of using nanoparticles as corrosion inhibitor in hydrocarbon production system.
