Hydrogen Sulfide Corrosion

Abstract A new method is proposed as a standard screening test for possible hydrogen sulfide corrosion inhibitors. This is a dynamic, weight-loss method which attempts to control conditions sufficiently well that substances which offer promise of being effective inhibitors under field conditions can be selected for further study. The test is cheap and simple, so that it can be run economically by a relatively untrained technician on large numbers of materials. The method is described and the reasons for choosing the particular conditions are explained. Then illustrations of the application of the procedure to a number of types of inhibiting substances are presented. 2.3.4

Abstract In chemical manufactures, the corrosion inhibitors were added in order to reduce the corrosion of mild steel. Chemical molecules are often used on mild steel surfaces as portion of the latest finishing steps before painting and/or storage. Here, this work elucidated the utilization of an isatin derivative, namely, 3-((3-acetylphenyl)imino)indolin-2-one synergistic with zinc oxide nanoparticles for improving the impedance of mild steel (MS) against corrosion in 1.0 M hydrochloric acid using the weight loss method and scanning electron microscopy (SEM). Weight loss measurements demonstrated that the best 3-((3-acetylphenyl)imino)indolin-2-one concentration was 0.5 mM and the inhibition efficiency was 83% whereas the inhibition efficiency was 92% with addition of ZnO NPs. 3-((3-Acetylphenyl)imino)indolin-2-one retards the corrosion process at 300 K and demonstrates low inhibition efficiencies at 310, 320 and 330 K.

In this paper, the anticorrosive effects of two types of corrosion inhibitors (anodic inhibitors and cathodic inhibitors) on rebars immersed in the simulated concrete pore solution with 3.5%( wt) NaCl were studied by the static weight loss method . The results are as following: firstly, all of the inhibitors had an anticorrosive effect on the rebars and sodium nitrite performed best. Besides, the higher the concentration, the more obvious effect .Secondly, diethanolamine had the best performance in the cathodic inhibitors. Thirdly, sodium nitrite had a good coordination effect with diethanolamine instead of being used alone. In this way, it can exist synergy and reduce the activity of cathode and anode by the formation of consecutively protective film on the surface of the rebars.

Inhibition Performance

The corrosion inhibition performance of molybdate and molybdate compound corrosion inhibitor of carbon steel in seawater were tested using weight loss method, electrochemical polarization curve, and the quaternary compound molybdate corrosion inhibitor were made sure through the experiments. The experiment results show that the compound corrosion inhibitors have obvious synergistic corrosion inhibition effects in the proportion of 40 mg/L molybdate, 10mg/L HEDP, 4mg/L Zn2+ and 50 mg/L glucose acid salts.

The inhibition efficiency of products have been measured by weight loss method with the concentration range from 10 mg/L to 1,000 mg/L in 1wt% HCl at different temperture. The inhibition efficiency of the modification product shows good inhibition efficiency after modified by formaldehyde and diethylamine, which is up to 89.31% at 60°C. The inhibitory effect of modification products is in accord with Langmuir adsorption equation.

Abstract Tread wear rates during first wear measured by groove depth and weight changes do not always agree. Sometimes, the groove depth method shows a high rate and the weight loss method a low rate. Reported here are experiments designed to determine if grooves show depth changes without wear. Four tires were measured before mounting on a wheel, after mounting and inflation, and after inflation and storage. The mounted and inflated tires showed shallower shoulder grooves and deeper center grooves than the unmounted tires. In a second experiment, tires were measured immediately after a tread wear test and then stored mounted for two weeks before remeasuring. Each groove became deeper, and there was no change in the crown radius of any tire.

The inhibition efficiency (IE) of sodium molybdate (SM) in controlling corrosion of carbon steel in an aqueous solution containing 120 ppm of Cl-, in the absence and presence of Zn2+has been evaluated by weight-loss method. A synergistic effect exists between SM and Zn2+when the concentration of Zn2+is 25 ppm and above. Inhibition efficiencies obtained are greater than 85%. Antagonistic effect exists between SM and Zn2+when the concentration of Zn2+is 10 ppm and below. The SM-Zn2+system shows excellent IE up to third day. Above third day IE decreases. Acceleration of corrosion takes place. Excellent IE is shown at pH 5,7 and 12. At pH 9, IE decreases since Zn2+is precipitated as Zn(OH)2in the bulk of the solution. Polarization study reveals that SM-Zn2+system functions as a mixed inhibitor. FTIR spectra reveal that the protective film consists of Fe2+-SM complex and Zn(OH)2.
