One inhibitor was studied in detail to determine the effect of solvent, temperature, concentration and contact time on inhibitor application. The laboratory corrosion tests used the rotating cylinder electrode and linear polarization to measure the corrosion rate. The corrosion rate was also verified by iron loss measurements. Inhibitor was extracted from the electrode surface and the quantity determined by gas liquid chromatography. The inhibitor was also detected on the surface of the electrode by Fourier Transform Infrared spectroscopy. Corrosion rate data monitored in the field and inhibitor residue on field coupons confirm the laboratory test data.
