Effect Of Organic Solvent On Corrosion Inhibition of Mild Steel in CO2 environment

Effect Of Organic Solvent On Corrosion Inhibition of Mild Steel in CO2 environment
Available for download

Corrosion inhibitors is commonly used to combat internal corrosion of mild steel pipelines in oil and gas production and transmission systems. Since the corrosive environment and flow conditions could vary in different fields, small scale laboratory testing is essential to determine the effectiveness of inhibitors in specific corrosive environments. To ensure the accuracy of inhibitor dosage in a small-scale lab setup, the inhibitor often needs to be pre-diluted before addition to the test electrolyte. This pre-dilution has the potential to lead to experimental errors. However, little information can be found about pre-dilution steps, and their influence on inhibition phenomena, in the open literature.

Injection of inhibitors is an economic and efficient way to combat corrosion of tubular steels utilized in the production and transmission of oil and gas. Given variability in the physicochemical environments encountered in the field, small scale laboratory testing is necessary to determine the effectiveness of inhibitors in specific corrosive environments. To achieve ppm concentrations of an inhibitor in a smallscale lab setup, the inhibitor often needs to be pre-diluted before addition to the test electrolyte, which has the potential to introduce experimental errors. One factor that affects the repeatability of corrosion inhibition testing is the volume of solvent used to dilute or dissolve the small amount of inhibitor prior to addition to the test environment. In this study electrochemical measurements, including linear polarization and potentiodynamic polarization, were utilized to evaluate the effect of different volumes (0.1 mL to 3 mL) of isopropanol used as a solvent for imidazolinium, pyrimidinium, and phosphate ester inhibitor model compounds in 2 L of a brine; a commercial corrosion inhibitor was also studied for comparison purposes.

Pyrolysis processes of post-consumer plastics are a promising chemical recycling route and a good alternative to disposal. Nevertheless, these processes are challenging for metallic materials since chlorine containing materials or biological components inside the feedstock can yield HCl and H2S, respectively, during cracking. In combination with high temperatures of the reactor zone metallic construction materials can be attacked by high-temperature corrosion.

The spread of disbondment or corrosion from a scribe or holiday in a coating film, for which the terms rust creepage or undercutting are used in this paper is an important mechanism of coating degradation. The mechanism of rust creepage has been well studied by several authors who concur that the mechanism is driven by electrochemical reactions15. The reactions occurring at the discontinuity in the coating (scribe or holiday) involve an anodic reaction in which iron is dissolved. Adjacent to the anodic region, under the coating, a cathodic reaction occurs in which oxygen is reduced to hydroxyl ions.

With the rapid development of China's economy, energy and transportation industries have developed rapidly, and more and more oil and gas pipelines and urban rail transit have been built and put into use. Urban rail transportation systems, such as subways or light rail, generally use direct current traction and backflow through the rail. Because the track is not completely insulated from the earth, it is inevitable that some electric current will be discharged from the track to the earth to form stray electric current, which will cause interference to the surrounding metal components such as buried oil and gas pipelines.
