Download or read book Anaerobic Pitting Corrosion of Carbon Steel in Marine Sulfidogenic Environments written by Bret Harrison Davis and published by . This book was released on 2013 with total page 298 pages. Available in PDF, EPUB and Kindle. Book excerpt: Microorganisms find their way into fuel tanks by multiple means. For example, some fuel tanks in U.S. Navy vessels utilize seawater to replace ballast lost to burned fuel. This introduces a consortium of aerobic and anaerobic fuel-degrading organisms that form biofilms on the tank's inner walls. These biofilms create oxic gradients; allowing aerobic and anaerobic organisms to live in synergistic alliance. The presence and activity of these organisms influence degradation of fuels and corrosion of tank materials. This thesis focuses on corrosion of iron under strict anaerobic (anoxic) sulfidogenic marine environments. Manganese sulfide (MnS) inclusions are known sites of pitting corrosion in carbon steel in aqueous environments. This work investigates pitting corrosion of carbon steel under exposure to sulfate-reducing organisms in anaerobic marine environments. It was found that pitting was initiated in the boundary regions of MnS inclusions at normal pH. Corrosion in general was more pronounced in the presence of a biofilm of sulfatereducing bacteria than in abiotic sulfide medium. It is proposed that the initiation of an anodic reaction leading to the dissolution of the Fe matrix and subsequent pitting of steel in the boundary regions of MnS inclusions is due to strain exerted on the Fe matrix by MnS minerals mixed within the Fe matrix at the interface due to metallurgical processes. We discovered that on the average only 1 out of ~2200 inclusions (or ~2 pits per mm 2 area) are activated to initiate pitting corrosion at normal pH. This increases very rapidly and reaches to pitting densities of ~4200 pits/mm 2 at acidic conditions (pH 4). The main reason for this is because MnS inclusions start dissolving at low pH conditions via MnS+ 2H -- H 2S + Mn 2. This mechanism produces H 2S abiotically, which auto catalyzes the pits to grow along the long (hundreds of microns) micro-wires of MnS inclusions. At certain locations these micro-pits join together to give rise to macroscopic pitting in metals.

This book was released on 2021 with total page 157 pages. Available in PDF, EPUB and Kindle. Book excerpt: Microbiologically influenced corrosion (MIC) is one of the operational threats that could lead to catastrophes such as liquid/gas leaks and even explosions, especially in the oil and gas system. MIC is caused by microbial biofilms. Sulfate reducing bacteria (SRB) is one of the corroive microorganisms commonly present in an anaerobic environment, e.g., in pipelines and reservoirs. Since sulfate is ubiquitous in these environments, SRB are almost unavoidable during operations. They are blamed for the majority of MIC cases. Other environmental microbes such as acid producing bacteria (APB) can also cause MIC. Biocides and physical scrubbing such as pipeline pigging operations are needed to mitigate biofilms and MIC. In the field environment, microorganisms typically live in synergistic microbial biofilm communities. In enhanced oil recovery (EOR) operations, the hydrolyzed polyacrylamide (HPAM), one of the popular polymers in EOR polymer flooding, is added to increase the injected fluid's viscosity prior to pumping to the downhole oil reservoir. HPAM degrades as a result of multiple microbial species in the consortium. Bacillus cereus can utilize the amide group of HPAM as their nitrogen source, while SRB can hydrolyze the amide group to carboxyl for acquiring a carbon source.

Download or read book Microbiologically Influenced Corrosion of Buried Mild Steel Pipes written by Arjumand Shah Bano and published by LAP Lambert Academic Publishing. This book was released on 2012-04 with total page 184 pages. Available in PDF, EPUB and Kindle. Book excerpt: Within the biosphere every object is influenced by microbial activities. A very unfamiliar case is represented by the microorganisms involved in the process of corrosion of different metals and their alloys. Many workers have reported bacteria responsible for initiating, accelariting and promoting the process of corrosion. While several recent authors have also documented corrosion inhibiting/controlling roles of microorganisms. It appears that like a healthier balance between the normal microbiota and pathogens, required for maintaining health of a host; a comparable balance among the members of microbial community of soil is required for protecting the buried mild steel pipes from corrosion based losses. This work reports isolation of both corrosion enhancing as well as corrosion controlling bacteria from an identified location. The bacterial isolates were then studied under laboratory but field simulated conditions to explore the roles of the monocultures of both catogaries of the bacteria. While effects of their co-cultures have also been delineated in comparable experimental set up. The findings are helpful in controlling corrosion of soil buried mild steel pipes.

Available in PDF, EPUB and Kindle. Book excerpt: Microbially induced corrosion (MIC) of steel due to the presence of sulfide is a leading cause of pit formation of carbon steel in fuel-seawater environments. While extensively studied, the exact causes of pitting corrosion in naval fuel tanks when exposed to MIC in the presence of fuel and seawater are not completely understood. This thesis focuses on the role that cold-rolling of carbon steel plays on corrosion while subjected to sulfidogenic, suboxic corrosive environments. Particularly, the effects of microscopic residual strain found within 1018 steel on the anodic dissolution of the metal is studied in different MIC sulfide environments using EBSD, AFM, FE-SEM, EDX, and electrochemistry. It is found that regions of increased plastic deformation of the crystalline lattice as a result of cold rolling correlate to an increase in anodic dissolution rates of 1018 steel coupons cut parallel to rolling direction. Image overlay provides a verification of the location of corrosion of samples to the same locations found in EBSD mapping taken prior to corrosion, ensuring the predictive value of EBSD analysis in establishing locations of accelerated corrosion. The effect of different corrosion environments on the corrosion rate of steel is measured through electrochemistry. Values obtained through these measurements are applied using mechanochemical theories to predict the localized dissolution rate of the steel due to strain using computational methods. Mechanochemical analysis of the strained areas results in predicted corrosion rates within an order of magnitude of the corrosion rates measured using AFM for the exposed time period at the same locations. Areas exhibiting increased corrosion rates occur in areas exhibiting increased strain as measured by EBSD analysis. Further electrochemical results show an increase in corrosion rates for suboxic sulfide rich systems containing low levels of oxygen, when compared to anaerobic sulfide environments. Variations in corrosion current density as a function of oxygen presence, as measured by electrochemistry, accurately predict variations in mechanochemical corrosion rates of strained areas well within an order of magnitude. Results from this study support the use of EBSD as a means to further the understanding of pitting corrosion as a function of material properties.

This book was released on 2017-03-03 with total page 532 pages. Available in PDF, EPUB and Kindle. Book excerpt: Microorganisms are ubiquitously present in petroleum reservoirs and the facilities that produce them. Pipelines, vessels, and other equipment used in upstream oil and gas operations provide a vast and predominantly anoxic environment for microorganisms to thrive. The biggest technical challenge resulting from microbial activity in these engineered environments is the impact on materials integrity. Oilfield microorganisms can affect materials integrity profoundly through a multitude of elusive (bio)chemical mechanisms, collectively referred to as microbiologically influenced corrosion (MIC). MIC is estimated to account for 20 to 30% of all corrosion-related costs in the oil and gas industry. This book is intended as a comprehensive reference for integrity engineers, production chemists, oilfield microbiologists, and scientists working in the field of petroleum microbiology or corrosion. Exhaustively researched by leaders from both industry and academia, this book discusses the latest technological and scientific advances as well as relevant case studies to convey to readers an understanding of MIC and its effective management.
