Development of a green corrosion inhibitor for use in acid cleaning of MSF desalination plant

摘要: Abstract A green and cost-effective inhibitor based on Date palm leaves extract was formulated for use during acid cleaning of thermal desalination plants. The formulation designated as F1 tested against the corrosion ferrous-based alloys namely: carbon steel, Ni-resist, 316L stainless steel in 2% HCl solution at 40 °C under static hydrodynamic conditions. Weight loss electrochemical methods complemented with scanning electron microscopy were used study. Experiments performed 6, 24, 72 h performance compared that a commercial inhibitor. exhibited excellent inhibition performance. Under dynamic conditions, 0.4% provided up to comparable inhibitors (F1 one) behavior typical mixed type studied environment according potentiodynamic polarization. Results from cyclic polarization experiments excluded pitting risk medium. all applied techniques are good agreement.
