Potential of using plant extracts as green corrosion inhibitors in the petroleum industry

In this paper, preliminary studies of ten different plant extracts as potential corrosion inhibitors carbon steel were examined. For each extract, the concentration range in which it shows anti-corrosion action was first determined, and then most effective determined for extract. The tests performed a brine solution saturated with CO2 at room temperature. aim study to isolate high effectiveness subsequent electrochemical surface methods determine mechanism inhibitory action. purpose, potentiodynamic polarization Tafel extrapolation. Among all tested extracts, lady’s mantle (92.17%) dandelion root (95.07%) stood out their effectiveness. Both showed behaviour mixed inhibitor dominant influence on anode process.
