Inhibition effect of thiobacillus denitrificans on the corrosion of X70 pipeline steel caused by sulfate-reducing bacteria in crude petroleum

Abstract: Although there are many reports demonstrating that thiobacillus denitrificans (TDN) may inhibit corrosion caused by sulfate-reducing bacteria (SRB), very little is known for the inhibition effect in crude petroleum. In this work, the inhibition effect of TDN on the corrosion of X70 pipeline steel caused by SRB in crude petroleum was studied. The optimum incubation condition of TDN was obtained by orthogonal experimentation. The growth characteristics of TDN and SRB in crude petroleum were reflected via analyzi… Show more

“…However, the residual chemical biocides will bring environmental pollution and induce the generation of strains with biocide resistance. Microbiologically influenced corrosion inhibition, by contrast, is friendly to environment and sufficiently efficient in preventing MIC (Qiu et al, 2015). Researchers have studied many bacterial species, such as iron-oxidizing bacteria, manganese-oxide bacteria, sulfur oxidizing bacteria, archaea and Thiobacillus denitrificans (TDN) (Liu et al, 2020).…”

“…Microbiologically influenced corrosion (MIC) is one of the main causes of metal corrosion [8,9]. Twenty percent of corrosion costs is attributed to MIC, leading to a great economic loss every year based on reports [10].…”

“…Therefore, metabolic activity of SRB is high in exponential phase and stationary phase, and low in death phase during SRB growth cycle. In the most of SRB induced corrosion cases, heterogeneous corrosion is the typical corrosion form, and it is influenced by absorption of biofilm, corrosive metabolic products, and SRB cells . However, little is known about the relationship between metabolic activity of SRB and heterogeneous corrosion of metal during SRB growing process.…”

“…The relationship between electrochemical reactions and surface micromorphology and composition in local areas is essential for intensive study of mechanism of heterogeneous corrosion, especially for initiation of localized corrosion. Conventional electrochemical methods, such as open circuit potential (OCP), electrochemical impedance spectroscopy (EIS), and polarization curve, have been widely used to investigate the corrosion involved in SRB . However, there is a limitation for these methods, that is, they cannot provide spatial information on the location and geometry of localized corrosion .…”
